A) covalent
B) ionic
C) coordinate
D) metallic
E) None of these
Correct Answer: B
Solution :
\[37=1{{s}^{2}},2{{s}^{2}},2{{s}^{6}},3{{s}^{2}}3{{p}^{6}},4{{s}^{2}},3{{d}^{10}},4{{p}^{6}},5{{s}^{1}}\] Thus, the element belongs to IA group and has valency +1. \[53=1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},4{{s}^{2}},3{{d}^{10}},4{{p}^{6}},5{{s}^{2}},4{{d}^{10}},5{{p}^{5}}\] Since, there are 7 electrons in the valence shell thus this element requires one electron to complete its octet, ie, has valency -1 Hence, element with atomic number 37 transfers its electron to the element having atomic number 53 and results in the formation of an ionic bond.You need to login to perform this action.
