What are the differences and similarities between molecule and element?

Answer 1

An atom refers to one specific atom usually, unlike an element which is a grouping of atoms who all share the same number of protons. Elements are the quasi-classifications for atoms to make referring to them and dealing with them easier. However, atoms of one element, meaning they have the same number of protons, do not always have equal amounts of neutrons. They can form isotopes, which have more or less depending on the isotope, but if you were to distinguish a single atom, you would find that its number of neutrons does not necessarily correspond to the rest of those of that element. In other words, atoms are the particles, elements are the type of particle.

Answer 2

A molecule contain :

# 2-3 atoms of an element; ex.: the molecule of ozone,O3, with 3 oxygen atoms.

# many atoms from different elements; ex.: the molecule of ethanol, C2H5OH, with 2 carbon atoms, 6 hydrogen atoms and 1 oxygen atom.

An atom is formed from protons, neutrons and electrons; and a molecule is formed from atoms.

Answer 3

A molecule is formed when two or more atoms chemically bond together, while an element is a pure substance consisting of one type of atom. Both molecules and elements are fundamental building blocks of matter. A key difference is that elements cannot be broken down further by chemical means, while molecules can be.
