Q60.Given below are the atomic numbers of some group 14 elements. The atomic number of the element with lowest melting point is : (1) 6 (2) 82 (3) 14 (4) 50
What This Question Tests
This question assesses the knowledge of periodic trends, specifically the melting point trend within Group 14 elements. It requires knowing that carbon (diamond) has the highest melting point and the trend generally decreases down the group from C to Sn, with Pb having a slightly lower melting point than Sn due to inert pair effect.
