Question

Consider the following statements:

Statement-1: Proton is a positively charged subatomic particle. Statement-2: Sodium atom contains one electron in its outermost shell.

Now, choose the correct option.

• A.
  Only statement 1 is correct
• B.
  Only statement 2 is correct
• C.
  Both the statements are correct
• D.
  Both the statements are incorrect

Answer 1

The correct option is C

Both the statements are correct
The proton is a positively charged subatomic particle found in the nucleus of an atom. It carries a charge of $+1.6\times {10}^{–19}C$.

The atomic number of sodium is 11. The electronic configuration of sodium atom is 2, 8, 1. Therefore, the outermost shell of sodium contains only one electron.

Hence, the correct answer is option (c).
