When two or more atoms join together, we call it a molecule. When two or more atoms of different elements join together, we call it a
compound
. All compounds are molecules, but not all molecules are compounds.
Is two atom an element?
No.
Two atoms of the same chemical element are typically not identical
. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.
Can a compound have 2 atoms?
Heteronuclear molecules
All other
diatomic molecules
are chemical compounds of two different elements. Many elements can combine to form heteronuclear diatomic molecules, depending on temperature and pressure. Examples are gases carbon monoxide (CO), nitric oxide (NO), and hydrogen chloride (HCl).
Is element a molecule?
Elements can be made of one atom
, like He, or be elemental molecules, such as hydrogen (H
2
), oxygen (O
2
), chlorine (Cl
2
), ozone (O
3
), and sulfur (S
8
). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.
Is an atom an element or compound?
Atom is a particle of matter that characterizes a
chemical element
.
What is difference between an element and a compound?
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. … Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be
separated by a chemical reaction
.
Is water an atom or molecule?
A water molecule has
three atoms
: two hydrogen (H) atoms and one oxygen (O) atom. That’s why water is sometimes referred to as H
2
O. A single drop of water contains billions of water molecules.
How many atoms are in an element?
An atom is an element. The two words are synonymous, so if you’re looking for the number of atoms in an element, the answer is always
one
, and only one.
Which is bigger element or molecule?
If it’s in the table, it’s an element! Atoms can join together – they form bonds together – to make
MOLECULES
. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H
2
for short. … Molecules can be much bigger.
Can a compound be made of the same element?
The
molecule can consist of atoms of the same element
, or atoms of different elements. Compounds are (in the chemical sense of the term) made of two or more elements. This means a lot of molecules (like H2O) are considered compounds (though H2 is not).
What is the structure of an atom?
An atom is
a complex arrangement of negatively charged electrons arranged in defined shells about a positively charged nucleus
. This nucleus contains most of the atom’s mass and is composed of protons and neutrons (except for common hydrogen which has only one proton).
Is gold a compound?
Gold is a
chemical element
with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. … Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).
What is the similarities between elements and compounds?
On first glance, elements and compounds might appear different, yet they share many similarities, like
being made up of atoms and having bonds linking their atoms together
. Elements and compounds also share the qualities of being both pure and homogeneous substances.
