(a)
Interpretation:
The number of protons and electrons in aS8 molecule needs to be deduced
Concept Introduction:
- Every system found in nature is a composite of atoms, molecules, ions or other particles
- These are composed of fundamental subatomic particles: protons, neutrons and electrons.
- Each atom is characterized by two quantities:
Atomic number (Z) andatomic mass (A)
Z = atomic number = number of protons = number of electrons ------ (1)
A = atomic mass = number of protons + number of neutrons ------ (2)
For an ion: number of electrons = number of protons + charge on the ion ------ (3)
(b)
Interpretation:
The number of protons and electrons in
