A nucleus represented by the symbol _ A ^ A X has:

A nucleus represented by the symbol AAX{ }_{\mathrm{A}}^{\mathrm{A}} \mathrm{X} has:

Options

  1. AZ\mathrm{Z} neutrons and A−Z\mathrm{A}-\mathrm{Z} protons
  2. BZ\mathrm{Z} protons and A−Z\mathrm{A}-\mathrm{Z} neutrons
  3. CZ\mathrm{Z} protons and A\mathrm{A} neutrons
  4. DZ\mathrm{Z} protons and Z−A\mathrm{Z}-\mathrm{A} neutrons

Correct answer

B. Z\mathrm{Z} protons and A−Z\mathrm{A}-\mathrm{Z} neutrons

Step-by-step solution

2=2= Number of protons A=A= Total number of protons and number ∴\therefore Number of neutrons A=A−Z\mathrm{A}=\mathrm{A}-\mathrm{Z}
