Question
Statement 1 : Electronegativity of group 14 elements decreases from Si to Pb.
Statement 2 : Group 14 has metals, metalloids and non-metals.
Options :
Both Statements 1 and 2 are correct
Both Statements 1 and 2 are incorrect
Statement 1 is correct and Statement 2 is incorrect
Statement 1 is incorrect and Statement 2 is correct
Answer :
Statement 1 is incorrect and Statement 2 is correct
Solution :
Electronegativity generally decreases as we move down the group but Pb has higher electronegativity than Sn.
• C ⇒ non-metal
Si and Ge ⇒ metalloids
Sn and Pb ⇒ metals
E.N. of Sn = 1.8, Pb = 1.9
