What substance is made up of atom?


Elements

A pure substance that is made entirely from one atom Eg:
Compounds Are pure substances made up entirely from two or more elements that are chemically combined Law of Conservation of Energy Mass cannot be created nor destroyed in ordinary chemical of physical changes

Are substance that are made up of more than one type of atom?

If a substance contains more than one type of atom, it is a

compound or a mixture

. The smallest particle of a compound is a molecule.

Is water composed of only one type of atom?

Water has a chemical formula of H2O , so

it cannot be composed of only one type of atom

, as it contains both hydrogen and oxygen atoms.

What type of substance is always made up of a single type of atom mixture element molecule compound?

All matter is composed of atoms. If a substance is made of only a single type of atom, then the substance is

an element

. Conveniently, all of the known elements are listed on the periodic table of elements. Substances like gold, silver, oxygen, carbon, hydrogen, and helium are all elements.

What contains only one type of particle?

Explanation: A substance containing only one type of atom is called

a chemical element

.

Is gold composed of only one type of atom?

Pure (24K) gold is composed of only one type of atom,

gold atoms

. Atoms are the smallest particle into which an element can be divided.

Is sugar composed of only one type of atom?

Sugar is made up of

carbon, hydrogen and oxygen atoms

. It’s the way these atoms are connected that makes each type of carbohydrate different. In each molecule of table sugar there are: 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. The black stuff is called burnt sugar!

Can a molecule have one atom?

2.8.

Elements can be made of one atom

, like He, or be elemental molecules, such as hydrogen (H

).

Is water wet?


Water isn’t wet because

it is a liquid that wets things. Once you come into contact with water you become wet. Until then water is liquid and you are dry.

What are two substances?

The two main types of pure substances are

compounds and elements

.

Which is an example of homogeneous substance?

A homogeneous mixture appears uniform, regardless of where you sample it. … Examples of homogeneous mixtures include

. Examples of heterogeneous mixtures include sand, oil and water, and chicken noodle soup.

Which pure substance is made up of more than one element?


Compound

. A pure substance, basically composed of two or more elements and chemically combined in a fixed proportion is called a compound. Therefore, water is a compound. It has two elements, hydrogen and oxygen, combined in a fixed ratio.

Are compounds made up of only one kind of particle?

All compounds are

molecules

, but not all molecules are compounds. That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms.

Which type of substance is made of only one kind of matter and has definite properties?

A B
pure substance

substance made of one kind of material having definite properties
element simplest type of pure substance; made up of atoms atom the basic building block of matter; the smallest particle of an element chemical symbol shorthand way of representing an element

Is baking soda a mixture or substance?

The sample will dissolve in water. When heated to 270°C the sample will decompose, giving off carbon dioxide and water vapor and leaving a residue of sodium carbonate. Thus, by definition, baking soda is

a pure substance

because it has a constant composition and a unique set of properties, some of which we have listed.

What are the 3 types of atom?

  • Description. Atoms are made of tiny particles called protons, neutrons and electrons. …
  • Stable. Most atoms are stable. …
  • Isotopes. Every atom is a chemical element, like hydrogen, iron or chlorine. …
  • Radioactive. Some atoms have too many neutrons in the nucleus, which makes them unstable. …
  • Ions. …
  • Antimatter.

Can hydrogen exist as a single atom?

Under the exceedingly low pressure conditions found in space,

hydrogen tends to exist as individual atoms

, simply because there is no way for them to combine; clouds of H2 form and are associated with star formation. The hydrogen atom A hydrogen atom is an atom of the element hydrogen.

Is Diamond an element?

Diamond is

composed of the single element carbon

, and it is the arrangement of the C atoms in the lattice that give diamond its amazing properties. Compare the structure of diamond and graphite, both composed of just carbon.

What is carbon hydrogen and oxygen make?


Carbohydrates

.

Carbohydrates

are organic compounds that contain only carbon, hydrogen, and oxygen. They are the most common of the four major types of organic compounds. There are thousands of different carbohydrates, but they all consist of one or more smaller units called monosaccharides.

How many atoms are in 2 waters?

Two water molecules contain

4 hydrogen atoms and 2 oxygen atoms

.

How many atoms are in a mole?

The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms =

6.022 × 1023 atoms

• The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).

Is Lava wet?

If we’re using it as an adjective (definition: covered or saturated with water or another liquid), then

lava is a liquid state so it therefore it’s wet

. … Lava does contain a lot of water, especially prior to eruption (when it’s called magma), but also as it flows across the ground,’ he explained.

Can ice be wet?

In 1842, the British physicist Michael Faraday observed that

ice is always wet

and forms a thin layer of liquid water. … In a cooled sample chamber, they observed the surface of water ice both in water vapor of saturated air, at equilibrium, and in dry air.

Is water really blue?

The water is in fact not colorless; even pure water is not colorless, but

has a slight blue tint to it

, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.

Can pure substance contain more than 1 kind of atom?

compound

consists of atoms, but there are more than one kind.

What is example of substance?

Examples of pure substances include

tin, sulfur, diamond, water

, pure sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate). Crystals, in general, are pure substances. Tin, sulfur, and diamond are examples of pure substances that are chemical elements. All elements are pure substances.

2

O, is a pure substance, a compound made of hydrogen and oxygen.

Is Salt a substance?

Ordinary table salt is called sodium chloride. It is

considered a substance

because it has a uniform and definite composition.

Can a pure substance have more than one element?

When we speak of a pure substance, we are speaking of something that contains only one kind of matter. This can either be

one single element

or one single compound, but every sample of this substance that you examine must contain exactly the same thing with a fixed, definite set of properties.

Can pure substances have more than one atom?

A pure substance is any sample of matter that contains only one type of material, either compound or atom. A couple of examples would be pure water (contains only one type of molecule), pure sodium chloride (one type of ionic compound), or pure gold (one type of atom).

What is homogenous and heterogenous?

In most technical applications homogeneous means that

the properties of a system are the uniform throughout the entire system

; heterogeneous (also inhomogeneous) means that the properties change within the system. … For example, homogeneous systems have the same composition, density and pressure throughout.

Which substance is a heterogeneous mixture?

Heterogeneous Mixtures

A heterogeneous mixture is a

mixture in which the composition is not uniform throughout the mixture

. Vegetable soup is a heterogeneous mixture. Any given spoonful of soup will contain varying amounts of the different vegetables and other components of the soup.

What is example of homogeneous and heterogeneous?

Heterogeneous mixtures are made up of a non-uniform composition, while homogeneous mixtures are made up of a uniform composition. For example,

water and sand

is a heterogeneous mixture — you can easily separate the sand from the water.

Is a compound made up of sodium and chlorine?

Chemically,

table salt

consists of two elements, sodium (Na) and chloride (Cl). Neither element occurs separately and free in nature, but are found bound together as the compound sodium chloride.

What is a compound but not a molecule?

Compound Basics

A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds.

Hydrogen gas (H

2

)

is a molecule, but not a compound because it is made of only one element. … Table salt (NaCl) is a common example of a compound with an ionic bond.

How are chemical compounds made?

A compound is a unique substance that forms

when two or more elements combine chemically

. Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons.
