Find ionic compounds

1:1

Explanation:

The ratio of metal cationic atom to non-metal anionic atom in the compound is 1:1.

This is an ionic compound.

This is because metal cationic atom has two valence electrons. Non-metal anionic oxygen has six valence electrons Calcium loses two of its valence electrons to be isoelectronic with Ar and this confers a stable configuration to it. Non-metal oxygen atom accepts the electrons and adds 2 to its 6 electrons to become isoelectronic with neon. So, 1 metal cationic atom combines with 1 non-metal anionic atom to form the compound.
