The first four ionization energy values of an element are 191,578,872 and 8982 K.cal . The number of chlorine atoms per molecule of the componds formed by it is
(a)
Among the elements A,B,C and D having atomic numbers 9,10,11 and 12 respectively , the correct order of ionization energies is:
B>A>C>D
B>A>D>C
A>B>C>D
D>C>B>A
In groups from top to bottom , IP decreases due to:
Increase in the atomic size
Increase in the screening effect of the inner electrons
Decrease in the screening of the inner electrons
Decrease in the size of the atom

(a)
Ionization energy directly proportional to
stable electronic configuration
nuclear charge
both 1 and 2
none of these
