Calculate the number of protons, neutrons and electrons in ( ₁₆³² ~S ²⁻ ).

Options

  1. A(14,18,16 )
  2. B(16,16,14 )
  3. C(18,16,14 )
  4. D(16,16,18 )

Correct answer

D. (16,16,18 )

Step-by-step solution

An element can be represented as ( _Z^A X ). where, (X= ) symbol of element (Z= ) atomic number or number of protons (A= ) mass number (= ) sum of number of protons and neutrons Therefore, for ( ₁₆³² ~S ⁻² ), number of protons (=16 ), number of neturons (=32-16=16 ) and electrons (=18 ) Hence, the correct option is (d).
