How does a molecule differ from an atom?

Answer 1

A molecule is 2 or more atoms bonded together. It could be the same element, such as H2 (hydrogen molecule) & O2 (oxygen molecule), or different elements, such as NaCl (sodium chloride - salt) or H2O (water)

Answer 2

A molecule is a bunch of atoms combined.

An atom is the smallest part of an element, that you can get without splitting the nucleus of the atom.

Molecules are made of more two or more atoms joined together. The atoms can be same or different elements. A single molecule is the smallest piece of matter you can have without changing its properties.

Example: O2(oxygen we breathe)and O3(Ozone) are different molecules with different properties but are all made of oxygen atoms.

Each atom is a pure form of an element. Molecules are combinations of atoms and as so can be a mixture of distinct elements.

AnswerWell, an atom is part of a molecule. Like the molecule H2O contains two hydrogen atoms and one oxygen atom.

Correct, in addition atoms have their own individual characteristics. Molecules have their characteristics from their atoms making up the molecule. eg. Chemical and Physical properties.

Molecules are formed from atoms. Atoms are the basic building blocks of matter. Matter comprised of only one atom type is an element. Some atoms will form bonds with other atoms and form compounds. These compounds are made up of molecules. Molecules are composed of two or more different types of atoms held together.

Answer 3

An atom is the smallest unit of matter that retains the properties of an element, composed of protons, neutrons, and electrons. A molecule is a group of two or more atoms held together by chemical bonds. In essence, molecules are made up of atoms.
