Question

An electrovalent bond or ionic bond is formed between

Answer 1

Answer:

the two atoms which complete their octet

Answer 2

Answer:

${\huge{\sf{\red{\underline{\underline{ ÅÑSWËR}}}}}}$

Atoms of metallic elements that have 1,2 or 3 valence electrons can lose electron(s) to atom of non-metallic element,which have 7,6 or 5 electrons respectively in their outermost shell and thereby forming an Electrovalent Compound.

• The chemical compounds formed as a result of the transfer of electrons from one atom of an element to one atom of another element are called ionic compounds.

Condition for formation:-

1. Low ionisation potential
2. High electrons affinity
3. Large electronegativity diffrence
