terms

a. Atomic Radii

b. Electronegativity

c. Electron gain enthalpy

d. Oxidizing agent

e. Reducing agent​

Answer 1

Atomic radii-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.

Electronegativity-Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.

Electron gain Enthalpy- Electron gain enthalpy of an element is the energy released when a neutral isolated gaseous atom accepts an extra electron to form the gaseous negative Ion i.e. anion. ... The electron gain enthalpy of an element is a measure of the firmness or strength with which an extra electron is bound to it.

Oxidizing Agent-0An oxidizing agent is a compound or element that is present in a redox (oxidation-reduction) reaction which receives electrons originating from a different species. The oxidant is a chemical compound which easily transfers atoms of oxygen or another substance in order to gain an electron.

Reducing agent- A reducing agent (also called a reductant, reducer, or electron donor) is an element or compound that loses or "donates" an electron to an electron recipient (called the oxidizing agent, oxidant, or oxidizer) in a redox chemical reaction. ... The glucose (C6H12O6) is being oxidized, so it is the reducing agent.
