Group 14 elements are also known as the carbon family, and they have similar physical and chemical properties. In terms of physical properties, the melting point of these elements increases down the group. This is due to the increase in atomic size and the number of electrons involved in metallic bonding as we move down the group.

 

Among the options provided, tin (Sn) is the element with the highest melting point. This is because it has the largest atomic size and the highest number of electrons involved in metallic bonding, making it more difficult to break these bonds and melt the solid.

 

Carbon (C) has a relatively low melting point because it forms covalent bonds, and the intermolecular forces between its molecules are relatively weak.

 

Silicon (Si) and germanium (Ge) have higher melting points than carbon, but lower than tin. This is because they have larger atomic sizes and more electrons involved in metallic bonding than carbon, but not as much as tin.
