No, not all atoms of the same element are identical. Contrary to Dalton’s theory — that atoms of the same element are identical — scientists discovered that atoms comprise smaller sub-atomic particles. Further experiment... More »

All atoms of the same element have the same number of protons in the nucleus and consequently have the same atomic number. All atoms of the same neutral element have the same number of electrons as well. More »

All isotopes of the same element share a common number of protons and electrons, though they vary in their relative numbers of neutrons. All isotopes of a given element are chemically identical, and they form bonds with ... More »

An atom represents the smallest part of an element that still retains the characteristics of that element, and the bonding between two or more atoms forms a molecule. Molecules are often defined as the smallest part of a... More »

An element is defined as a substance made up of atoms with a specific number of protons. That means that every atom with 1 proton is always a hydrogen atom. Elements cannot be broken down further by chemical means and al... More »
