Chapter–1: Filling blanks.

The number of bonds which silicon usually forms to complete its valence shell and obey the octet rule is (a)   .

The element having a high electron affinity favors the formation of a/an (a)   .

(a)   bonding occurs by sharing valence electrons between the atoms involved in the bond.

The strength of sharing or transferring the valence electrons depends on the (a)   of the atoms involved in the chemical bonding.

For an atom, the number of valence electrons is equal to its (a)   number in the Periodic Table.

The attraction between a negatively charged ion and a positively charged ion is a (an) (a)   attraction.

(a)   chloride ions are needed to cancel the 2+ charge of magnesium in magnesium chloride.

A chemical bond formation that involves the complete transfer of electrons between atoms is called a(an) (a)   bond.

The number of lost or gained electrons by an atom during ionic bonding is the same as the (a)   of that element.

Atoms that have a positive or negative charge are called (a)   .
