1st ionization energy of magnesium is………..
a) + 496kj/mol
b) - 496kj/mol
c) + 738kj/mol
d) - 738kj/mol
The energy required to remove 2nd electron after removal of 1st electron is called.………..
a) 2nd electron affinity
b) 2nd ionization potential
c) 3rd ionization potential
d) none of these
Ionization energy depends upon…….……….
a) nuclear charge
b) atomic radius
c) electronic configuration
d) all of these
The ionization potential ………. in groups from top to bottom.
a) decreases
b) increases
c) remains same
d) none of these
Explanation:In case of groups ionization potential decreases as the size increases in groups and attraction of nucleus decrease on the outermost electrons and electrons can be easily removed with few amount of energy so least energy is required to ionize.
The ionization potential ………. in periods from left to right.
a) decreases
b) increases
c) remains same
d) none of these
Explanation:In periods ionization potential increases as the size decreases and attraction of nucleus on valence electrons increases so higher energy is required to remove the electron .
The elements at the top have…..…ionization energy than the elements at the bottom.
a) greater
b) lower
c) same
d) none of these
