(a)
Interpretation:
The elements with highest third ionization energy in periodic table hasto beidentified.
Concept introduction:
Ionization energy:
In a gaseous state isolated neutral atom, the amount of energy required to eject an electron from outermost shell is known as ionization energy. Ionization energy increases from left to right across periods due to increase of effective nuclear charge. Ionization energy decreases down the group due to addition of electrons enters into new orbital which is far from nucleus.
(b)
Interpretation:
The elements with highest seventh ionization energy in periodic table has to be identified.

- Predict the larger ion in each of the following pairs. Give reasons for your answers. (a) O,S2 (b) Co2+,Ti2+ (c) Mn2+,Mn4+ (d) Ca2+,Sr2+arrow_forwardTwo elements are in the same group, one following the other. One is a metalloid; the other is a metal. Both form oxides of the formula RO2. The first is acidic; the next is amphoteric. Identify the two elements.arrow_forwardOf the five elements Al, Cl, I, Na, Rb, which has the most exothermic reaction? (E represents an atom.) What name is given to the energy for the reaction? Hint: note the process depicted does not correspond to electron affinity E+(g)+eE(g)arrow_forward
