Ionization energy of ca 2+
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 … Web2) Be > Mg > Ca . 3) B > C > N. 4) Ge > Si > C . Answer: Logic & solution: 1) K > Na > Li : Incorrect, since ionization energy decreases down the group with increase in size. These elements belong to same group (1st). The correct order of first ionization energy should be: K …

WebCesium – as the largest atom, the lowest ionization energy and the most reactivity with nonmetals. This can be determined by its position lowest in the alkali metal group. 2. Write the charge that each of the following atoms will have when it has a complete set of valence electrons forming an ion. O – 2- Na 1+ F 1- N 3- Ca 2+ Ar - none 3. 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.
