What is a ionic covalent?

Answer 1

In an ionic covalent, the atoms "share" the electron. In this case, the two chlorine atoms share an electron, enabling them to both achieve a stable valence shell. Sometimes, there is an unequal sharing of the electrons. This is known as Polar Covalent bonds. One note about covalent bonds - they can only occur when two electrons are shared by non-metallic atoms.
