What is Atomic Radius?
The size on the atom, meaning the distance from the nucleus to the valence electrons
The amount on energy required to remove an electron from an atom in the gaseous state
Is a measure of the tendency of an atom to attract a bonding pair of electrons or its ability to gain electrons in a bond
The number of protons and neutrons found in the nucleus of an atom.
