Question

A) Define a chemical bond b) an electrovalent Bond c) a covalent bond

Answer 1

Explanation:

Chemical bond:

Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species that make up the familiar substances of the everyday world. When atoms approach one another, their nuclei and electrons interact and tend to distribute themselves in space in such a way that the total energy is lower than it would be in any alternative arrangement. If the total energy of a group of atoms is lower than the sum of the energies of the component atoms, they then bond together and the energy lowering is the bonding energy.

Electronic bond:

In the United States, a formerly-issued savings bond, exempt from state and local taxes, with a fixed interest rate. ... They began to be issued to help finance American involvement in World War II; they were known colloquially as war bonds.

Covalent bond:

A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

Answer 2

Answer:

a) chemical bond- Attractive force that hold atoms or ions together to form molecules or compounds are called chemical bond. .

b) electrovalent bond- The attractive force between oppositely charged ions that holds the ions together is called electrovalent bond. ..

c) covalent bond- when two atoms share electrons, they form a bond called covalent bond..
