helpFour elements have the following radii $($in ppm$)$: $117,122,129$ and $134.$ The elements

in random order, are V$,Cr,Nb$ and $Mo.$ Which element has a radius of $117ppm$ and

which has a radius of $134ppm?$

Four elements have the following first ionization energies $($in $k\frac{J}{m}ol)$: $462,409,479$

and $458.$ The elements, in random order are Ga$,$ Ge$,$ In and Sn$.$ Based on the trend

across the periodic table, which element has an ionization energy of $458k\frac{J}{m}ol$ and

which has an ionization energy of $462k\frac{J}{m}ol?$
