Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of lonizations by increasing amount of energy
required.
In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require
the next least energy, and so on.

Expert Solution

Step 1

The minimum amount of energy required to remove outermost shell electron form an isolated Gaseous atom to change it into cation is known as ionization energy.

For first electron removal the energy is known as first ionization energy.

It increases from left to right in period while decreases from upto down in a group.

The first ionization energies of the different elements given below -

Silicon - 786 kJ/mol

Radium - 509 kJ/mol

Helium - 2372 kJ/mol

Strontium - 550 kJ/mol

Arsenic - 947 kJ/mol

Therefore, correct sequence is as -
