Elements in a group are chemically similar to each other.

The periodic table is an arrangement of elements in groups and periods. The elements in the same group share a lot of chemical similarity with each other. The elements that are in the same period only have the same number of valence shells.

The elements described by each statement is;

(a) Smallest atomic radius in Group 6A(16) - oxygen

(b) Largest atomic radius in Period 6 - cesium

(c) Smallest metal in Period 3 - Aluminium

(d) Highest IE₁ in Group 4A(14) - carbon

(e) Lowest IE₁ in Period 5 -  Bismuth

(g) Group 3A(13) element that forms the most basic oxide -  Thallium

(h) Period 4 element with filled outer level - krypton

(i) Condensed ground-state electron configuration of [Ne] 3s²3p² - silicon

(j) Condensed ground-state electron configuration of [Kr] 5s²4d⁶- xenon

(k) Forms 2+ ion with electron configuration [Ar] 3d³ - vanadium

(l) Period 5 element that forms 3+ ion with pseudo–noble gas configuration - Indium

(m) Period 4 transition element that forms 3+ diamagnetic ion - Scandium

(n) Period 4 transition element that forms 2+ ion with a halffilled d sublevel - Manganese

(o) Heaviest lanthanide - Lutetium

(p) Period 3 element whose 2- ion is isoelectronic with Ar - sulfur

(q) Alkaline earth metal whose cation is isoelectronic with Kr - Strontium

(r) Group 5A(15) metalloid with the most acidic oxide - nitrogen
