Question

11. In which of the ionic compounds given below there is no octet in the outer shell of either the cation or the anion 2 a) NaCl b) NaH c) LiH d) LicI​

Answer 1

==========================

A

==========================

Explanation:

Compounds that consist of ions are known as ionic atoms. Atoms that gain or lose electrons are called ions, ions may have a negative charge or positive charge. Nonmetals lose electrons to gain negative charge and form anions, whereas metals lose electrons to gain positive charge and form cations. Anions are ions that have negative charge and cations are ions that tend to have a positive charge. Ionic bonds are generally between metals and non-metals.

Answer 2

The correct option is d and c.

. In LiCl and LiH there is not octet in the outer shell of the cation.

• In NaCl and NaH both the cation and annion has octet in its valance shell.
• But in case of LiH and LiCl the annions chloride ion and hydride ion has filled valance shell but the lithium cation has 0 electrons in its valance shell. So, it has no octet.
