Question

Element z reacts with bromine to form an ionic compound zbr2

Answer 1

Explanation:

Physical properties of ZBr₂

The compound is an ionic substance. Therefore it will have properties of ionic compounds. Some of these properties are:

• it is a hard solid usually with high melting points or a liquid with high boiling points.
• Soluble in water and insoluble in non-polar solvents.
• It can conduct electricity in aqueous solutions or in molten form.
• it will undergo a fast reaction.

Z is a metal

To form ionic compound, a metal will combine with a non-metal. Bromine is a non-metal and it is expected that Z will be a metal. This is because ionic bonds involves transfer of electron from one specie to the other. Metals are usually the donor and non-metals are the receptor. This is how ionic bond forms. The electrostatic attraction resulting from the ions produced the ionic bond.

Formula of the oxide

ZO

                 Z                           0

                +2                         -2

It is obvious that Z has 2 valence electrons. It will lose the two valence electrons to attain stability.

Oxygen requires 2 electrons to resemble Neon. This combination will give a compound ZO.
