Ionization energy of ca 2+
WebFor A r, K X + and C a X 2 +, C a has the highest atomic number so of these three, it would be most difficult to ionize C a X 2 +. Now it is just necessary to compare the ionization of M g X 2 + to C a X 2 +. Since the 2 p orbitals are closer to the nucleus than the 3 p orbitals, it will be harder to ionize M g X 2 + than C a X 2 +. Share Web(i) K+, Ar, Cl-:The correct order is Cl- < Ar < K+.All the three species are isoelectronic, each containing 18 electrons. The nuclear charge increases in the order Cl- (+17) < Ar (+18) < K+ (+19). As the nuclear charge increases, the attractive force between the nucleus and the same number of electrons also increases. This results in the decrease of size and hence …

Web(d) Successive ionization energies are higher for every element. 2 n d ionization of K happens from 3 s 2 3 p 6 configuration which is an inert gas configuration and for C a it happens from 4 s 1. So, K has higher second ionisation energy than Ca. WebIonization energy, also called ionization potential, is the energy necessary to remove an electron from the neutral atom. X + energy → X+ + e− where X is any atom or molecule capable of being ionized, X + is that atom or molecule with an electron removed (positive ion), and e − is the removed electron.
