Q1:

The atomic number of silicon is 14. It can be therefore concluded that

A a silicon atom contains 14 protons

B a silicon atom contains 14 neutrons

C a silicon atom contains 14 electrons

D all of the above

ANS:D - all of the above

Answer is D.

Because,
Number of neutron = Atomic Weight-Atomic Number.
= 28-14=14.
and atomic Number= No.of Electron=No.of Proton.
