Question

Define ionization energy? And Electronegativity?give their trends in groups and periods

Answer 1

Answer:

Development is always deliberated with economic connotations and it is referred to as an increase in the gross national product or in per capita income. In this understanding,development is equated with growth and it is envisioned that a quantum increase in the production of goods and services would bringdevelopment.

śElectronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegativeelement) is assigned a value of 4.0, and values range down to cesium and francium which are the leastelectronegative at 0.7.

Answer 2

Answer:

In physics and chemistry, ionization energy or ionisation energy, denoted Eᵢ, is the minimum amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated neutral gaseous atom or molecule.

Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards 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.
