Elements 19 and 22 are in the same period. Which will have the most in common chemically with element 72?
hafnium
potassium
sodium
titanium

The answer is titanium.

Explanation:

Titanium (element 22) shares the same group - or column - as element 72, so they will have more properties in common.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
