Anitride ion has 7 protons, 8 neutrons, and 10 electrons. what is the overall charge on this ion?

The overall charge on this ion is -3.

Solution:

Protons : These are the subatomic species which carries positive charge.

Electrons: These are the subatomic species which carries negative charge.

Neutrons: These are the subatomic species which doesn't carry any charge.

The net charge on the ion will be = (number protons)(charge carried by the protons.) + (total number of electrons)(charge carried by the electrons)

Numbers of proton = 7

Numbers of electrons = 10

So, net charge on the nitride ion =

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
