Atoms like to be have FULL OUTER SHELLS - To be STABLE!

Ionic Bonding:
One atom LOSES an electron from its outer shell, and GIVES it to another atom.

The atom that LOST the electron becomes POSITIVE.
Because, there are now LESS electrons to protons.
And the atom that GAINED an electron is now NEGATIVE.
Because it now has MORE electrons than protons.

Covalent Bonding:
When atoms SHARE electrons in their outer shells.

Water has 6 electrons in its outer shell.
Hydrogen has 1 electron in its outer shell.
So, it shares electrons with 2 Hydrogen atoms, to make H20!

Hope this helped:)

Ionic bond is when it ditches the electron ( we use to call it dich the *****) and covalent is when the electrons are shared (married couples)

Ionic is between a metal and a non metal, covalent is between two non-metals and metallic is between two metals. and then all that electron stuff further up ^^

Ionic bonding is the force of electtrostatic forces of attraction between oppisitly charged ions wheras covalent bonding is the sharingof outer electrons between two atoms

Atoms need to have a full outer shell

 Ionic bonding - Inonic bonding happens between metals and nonmetals. Metal loses an electron and becomes positive ion whereas nonmetals gans and electron and gorm negative ion to gain complete outer shell. Since they have opposite charges there is a strong electrostatic forces of attraction between them which is called ionic bond

Covalent bonding - Covalent bonds form when two nonmetal atom share a pair of electron.
