Question

C. Define :

i. Ionization.

ii. Electronegativity.

iii. Atomic size.

iv. Coordinate bond​

Answer 1

Answer:

1. Ionisation : Process in which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules.

2. Electronegativity : Tendency of a atom to attract shared electrons to itself.

3. Atomic size : Distance between the centre of the neculas of an atom and it's outermost shell.

Answer 2

Answer:

Ionization, in chemistry and physics, any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions). ... Ionization is one of the principal ways that radiation, such as charged particles and X rays, transfers its energy to matter.

Electronegativity, symbolized as χ, is the tendency of an atom to attract shared electrons to itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.

The atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.

A coordinate bond (also called a dative covalent bond) is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom. A covalent bond is formed by two atoms sharing a pair of electrons. The atoms are held together because the electron pair is attracted by both of the nuclei.
