Question:medium

Atomic numbers of three elements \(E_1, E_2\) and \(E_3\) of periodic table are \(Z_1, 50\) and \(Z_2\) respectively. From the position of the elements shown in figure, the value of \((Z_2 - Z_1)\) is

Show Hint

Use magic numbers to find atomic numbers in groups. Group 13: B(5) \(\xrightarrow{+8}\) Al(13) \(\xrightarrow{+18}\) Ga(31) \(\xrightarrow{+18}\) In(49) \(\xrightarrow{+32}\) Tl(81). Group 14: C(6) \(\xrightarrow{+8}\) Si(14) \(\xrightarrow{+18}\) Ge(32) \(\xrightarrow{+18}\) Sn(50). Group 15: N(7) ... Sb(51) \(\xrightarrow{+32}\) Bi(83).
