...of an element is the energy required to remove one electron from each atom in one mole of gaseous atoms to form unipositive gaseous ions.
First Ionisation Energy
4 of 18
Atoms of the same element that have different masses. Isotopes of an element have the same number of protons but different numbers of neutrons.
Isotopes
5 of 18
It is the weighted mean mass of an atom of an element compared with 1/12 the mass of an atom of carbon-12 which is taken as 12 exactly.
Relative Atomic Mass
6 of 18
This is the result of sharing a pair of electrons.
Covalent Bonding
7 of 18
It is the mass of an atom of an isotope of the element compared with 1/12 the mass of an atom of carbon-12 which is taken as 12 exactly.
Relative Isotopic Mass
