Boron typically forms three bonds and has no lone pairs due to its electron configuration.
Germanium typically forms four covalent bonds and has no lone pairs in its ground state.
In the case of carbon (C), it typically forms 4 bonds and has 0 lone pairs.
None.
There are three lone pairs present in chlorine atom
In SiCl4, silicon has no lone pairs because it forms four bonds with chlorine atoms, satisfying its octet rule.
There are no lone pairs in the nitrate ion (NO3-). The nitrogen atom forms three sigma bonds with oxygen atoms, leaving no non-bonding pairs of electrons.
There are two lone pairs on the sulfur atom in SO2Cl2. The sulfur atom has a total of 6 valence electrons, with two bonds to oxygen atoms and two bonds to chlorine atoms. This leaves two lone pairs of electrons on the sulfur atom.

H2SO4 does not have any lone pairs. It has 2 bonding pairs shared between sulfur and oxygen in each of the O=S=O bonds. Each oxygen also has 2 unshared pairs of electrons.
There are no lone pairs on the central atom in BCl3 because boron (B) is in group 13 (or 3A) and can have only 3 bonds around it.
