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 »

Carbon atoms are the building blocks for carbon, which is the sixth most abundant element found in the universe. A carbon atom has six electrons, four of which are in the outer shell of the atom, its valence shell. 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 »

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 »

Elements are made of atoms, which are particles that represent the most basic form of an element. An atom is the smallest particle of an element and cannot be further divided without becoming a less complex particle; in ... More »
