Calcium becomes a +2 ion and each chlorine becomes a -1 ion. The +2 calcium ion and the two -1 chloride ions attract each other and form an ionic bond and the compound calcium chloride. One calcium ...

The higher an element's electronegativity ... We were amazed to discover that his scale did not match either theoretical or experimental bond energies for significantly ionic molecules.” He continues: ...

The properties of elements and compounds can be explained by considering the different types of bonding present inside the molecules. All ionic compounds have a high melting point and boiling point.

The formula of an ionic compound can be deduced from the formulae of its ions. Remember that for the metal elements in groups 1, 2, and 3 the charge on the ion can be deduced by how many outer ...

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...
