Which statement below is not true? A. The nucleus is positively charged because of the protons.

B. The positively and negatively charged subatomic particles determine the atomic mass of an atom.

3.A neutral atom will contain the same number of electrons as protons.

4.Neutrons are not charged particles, are found in the nucleus and have a mass of 1
amu.

yes it is balanced

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.

c
