Question

Which of the following properties increase as you move from left to right across a period? Select all that apply.

A)Ionization energy
B)None
C)Electronegativity
D)Atomic radius

Answer 1

electronegativity is the right answer here

Answer 2

Answer:

As we move from left to right across a period.

Ionisation energy : increases

ionisation energy :

the amount of energy to remove the most loosely bound electron from an isolated gaseous atom to form a gaseous ion is called the ionisation energy of an atom.

In general, ionisation energy increases on moving from left to right in a period and decreases on moving down a group

Atomic radius :

Atomic radius is regarded as the distance from the centre of the nucleus to the outermost shell of the electron.

In general, atomic radius decreases on moving from left to right in a period and increases on moving down a group.

Electronegativity  :

the tendency of an atom to attract the bonding or shared pair of electrons towards its own side in a covalent bond is called the lectronegativity of an atom.

In general, electronegativity increases on moving from left to right in a period and decreases on moving down a group.
