The ionization energy is energy required to remove an electron from element in it's gaseous state.
Ionization energy is defined as the minimum energy required to remove an electron from its valence shell of an isolated gaseous atom,positive ion or molecule.Ionization energy is positive for neutral atoms from which it can be concluded that ionization is an endothermic process.
Closer are the valence electrons to nucleus ,higher is the ionization energy.It is usually expressed in electron volts or joules.Ionization energy increases from left to right in a period as more energy is required to remove electrons with small atomic size.
Ionization energy decreases down the group as atomic size increases due to which electrons are easily lost from the valence shell.

b. The temperature increases.
c. The temperature remains the same.
The correct answer is A. In the combined gas law, if the volume is decreased and the pressure is constant, then the temperature decreases.
P1V1/ T1 = P2V2 / T2
Assume the volume decrease by half; V2 = V1/2
P1V1/ T1 = P2V1 /2 T2
Cancelling terms,
1/T1 = 1/2 T2
T2 = T1/2
Thus, the temperature decreased.
The elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.
Metals and nonmetals are the elements in the periodic table that gains and lose electrons to form chemical bonds.
The metals are a compound that loses electrons and nonmetals gains electrons to form a chemical bond.
Lithium has been a group 1 element with 1 valence electron. It has been bonding with the nonmetals that accept the electrons and form the bond. The elements complete their octet and become stable.
The nonmetals that require an electron to complete their octet are halogens. Thus, the elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.
