sodium + chlorine → sodium chloride magnesium + oxygen → magnesium oxide calcium + chlorine → calcium chloride lithium + oxygen → lithium oxide In all of these reactions, the metal atoms ...

A small piece of sodium metal is placed in a flask of chlorine gas ... The +2 calcium ion and the two -1 chloride ions attract each other and form an ionic bond and the compound calcium chloride. One ...

The atoms in the reactants are: 1 calcium atom, 2 chlorine atoms, 2 sodium atoms, 2 hydrogen atoms, 2 carbon atoms, and 6 oxygen atoms The atoms in the products are: 1 calcium atom, 2 chlorine atoms, ...

So, for example, oxygen in group 6 gains two electrons ... magnesium ion and the two chloride ions are the ionic bonds. Final example – sodium oxide. TULELA: We’ll go through this one in ...
