Question

Difference between element and atom.With examples

Answer 1

Atoms are the smallest bits of ordinary matter and are made from particles called protons, neutrons and electrons. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.

An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

A single "piece" of water, H2O is a molecule.

It contains 2 elements: Hydrogen, and Oxygen.

But it contains 3 atoms, 2 Hydrogen, and 1 Oxygen.
