17. Which statement best describes the substance that results when electrons are transferred from a metal to a
nonmetal?
a. It contains ionic bonds and has a low melting point.
b. It contains ionic bonds and has a high melting point.
c. It contains covalent bonds and has a low melting point.
d. It contains covalent bonds and has a high melting point.

The chemical bond which involves the complete transfer of valence electrons between atoms is known as Ionic bond and the compound formed is known as Ionic compound.

In this type of bond metal completely loses its outermost shell and makes a positive charged ion called cation and nonmetal accepts those electrons to become a negatively charged ion called anion. This bond is very strong and having high melting and boiling point.

For example NaCl is an ionic compound

Na(Sodium) has 1 electron in its outermost shell.It loses its ! electron to become stable whereas Cl(Chlorine) has & electrons in its outermost shell. it gains the losed electron to complete its octave and become stable.

And it forms NaCl .

Answer:

It contains ionic bonds and has a high melting point. B-option

Explanation:

This is a question which needs to be solved by knowing the definitions of ionic and covalent bonds.

Ionic bonds are formed due to the donation of electrons from one atom to another.

Covalent bonds are formed due to the sharing of electrons from one atom to another.

In the given case it is said that donation of electrons is taking place between metal and non metal. By donation we understand that it is a ionic bond formation. The atoms being a metal and non metal the bond would be pretty strong and hence the melting point would be very high.

Hence we conclude that the bond is ionic and has high melting point.
