Question

give a detail how ionic bond formed?​

Answer 1

$\bigstar\huge\bf\underline{\underline{Answer:-}}$

Ionic bond is formed by transfer of electrons between metals and non-metals

Covalent bond is formed by sharing electrons between non-metals.

$\bigstar\huge\bf\underline{\underline{Explanation:-}}$

• Ions that have opposite charges will form an ionic bond in such a way that total charge on the compound is 0.

• e.g. Na forms Na⁺ ion and Cl forms  Cl⁻ ions to form a stable octet, which is given by the octet rule.

• So the compound formed will be  Nacl as the opposite charges cancel each other to give 0 charge, which is favourable.

• Covalent bond can be formed between non-metals having like charges e.g Sulphur and oxygen both have -2 charge on their ions, but  SO₂

• is formed by sharing 2 electrons in the outermost shell so that both elements gain a stable octet

Answer 2

$\huge\mathtt\red{AnsWeR࿐</p><p>}$

Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. ... The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).
