Give explanations for the large drops in melting point from C to Si and from Ge to Sn.
____ [38]

As we move down the group, the metallic bond becomes more stable and the formation of forming covalent bond decreases down the group due to the large size of elements.

Covalent and metallic bonding leads to higher melting points. Due to a decrease in attractive forces from carbon to lead there is a drop in melting point.

Carbon forms large covalent molecules than silicon and hence has a higher melting point than silicon.

Similarly, Ge also forms a large number of covalent bonds and has a smaller size as compared to that of Sn. Hence melting point decreases from Ge to Sn.

The order will be C>Si>Ge>Pb>Sn.

Every element have different atoms.

  • Over a hundred elements have been identified by scientists.
  • Atoms are the smallest particles that takes part in chemical reactions.
  • Elements are distinct substances that cannot be split.
  • Atoms of all elements do not have the same mass and volume. Isotopes are examples.
  • It is true that atoms of all elements have different masses and also different volumes.
  • The volume of an atom is function of the number of electrons it contains.
