MATCH the sub-atomic particles with their descriptions. Neutron
Electron
Quark
Proton

A. Smallest theoretical particles of protons and neutrons
B. + charge; located in the nucleus
C. no charge; located in the nucleus
D. - charge; located outside the nucleus

Explanation:

Neutron - no charge, located in the nucleus.

electron - - charge, located outside the nucleus.

Quark- smallest theoretical particles of protons and neutrons.

proton- + charge, located in the nucleus.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
