three types
of molecules which are the element molecule, the compound molecule & the mixture.

What are two molecules together called?
Every combination of atoms is a molecule. 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.
What are the 2 molecules?
Diatomic molecules
are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning “two”. If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H
2
) or oxygen (O
2
), then it is said to be homonuclear.
How do you identify a molecule?
- Draw the Lewis Structure.
- Count the number of electron groups and identify them as bond pairs of electron groups or lone pairs of electrons. …
- Name the electron-group geometry. …
- Looking at the positions of other atomic nuclei around the central determine the molecular geometry.
What is molecule called?
molecule,
a group of two or more atoms
that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
What is the largest molecule?
MEET
PG5
, the largest stable synthetic molecule ever made. With a diameter of 10 nanometres and a mass equal to 200 million hydrogen atoms, this tree-like “macromolecule” paves the way for sophisticated structures capable of storing drugs within their folds, or bonding to a wide variety of different substances.
What is the smallest molecule?
The smallest molecule is
diatomic hydrogen (H
2
)
, with a bond length of 0.74 angstroms. Macromolecules are large molecules composed of smaller subunits; this term from biochemistry refers to nucleic acids, proteins, carbohydrates, and lipids.
Can we see a molecule?
This, believe it or not, is a
microscope
. It can help us see very small particles like molecules by feeling the particle with the tip of its needle. These very powerful microscopes are called atomic force microscopes, because they can see things by feeling the forces between atoms. …
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.
What is a molecule class 9?
A group of two or more than two atoms of the same or different elements that are chemically bonded together
is called a molecule. For example: Two atoms of hydrogen (H
2 )
and one atom of oxygen (O
2
) react with each other and form one molecule of water.
What is a molecule for kids?
definition: the smallest unit of a substance that has all the properties of that substance. A molecule is
made up of a single atom or group of atoms
. Each molecule of water has one hydrogen and two oxygen atoms. Word History.
What is difference between compound and molecule?
Important Difference between Molecules And Compounds
Molecules are
two or more atoms chemically joined together
. Compounds are two or more different elements joined together chemically.
Why does oxygen form a molecule?
The O
double bond O bond is strong
and this means that, in the absence of something else to react with, eg a metal or hydrogen, two oxygen atoms will readily react with one another to form an oxygen molecule.
What happens when two molecules combine?
When atoms combine through chemical bonding, they form
compounds
—unique structures composed of two or more atoms. The basic composition of a compound can be indicated using a chemical formula.
