Hi, I am Dr. Science. I am here to teach you about Chemical Bonds! Lets start with ionic bonds.
Valance electrons relate to ionic bonding in a way. Ionic bonding is about getting a full valant shell.
Ionic bonding is a type of chemical bonding. Ionic bonding is the trasfer of electrons from metals to non metals in order to get a full valance shell.
By sharing the valance electrons , the outer shell can fill up with electrons.
Next, lets learn about colavalent bonding. A colavalent bond is a type of chemical bond. Colavalent bonding involves the sharing of electron pairs between atoms.
Periodic trends can mess with chemical bonding. One way this happens is because of how the elements are arranged on the periodic table. Sometimes periodic tables will order things diferently. They could order them by there atomic number, charge, etc.
