Ionic & Covalent Bonds
Ionic Bonding is a chemical bond with a metal and nonmetal ion that happens through electrostatic attraction. So basically its a bond that is formed by the attraction of two opposite charged ions
Covalent Bonds involve the sharing of pairs of electrons. They share electrons so they can have a full shell and gain more stability.
Relation between valence electrons and ionic bonds and covalent bonds
Covalent Bond: Covalent bonds involve the sharing of a pair of valence electrons by two atoms.
How periodic trends affect bonding
Period trends affect bonding because of the way the elements are arranged. They can be arranged by atomic radius, ionization energy, and electronegativity.
