Question

Why does Sulfide have a 2 Charge?

Answer 1

• Sulfur belongs to Group-16 of the p-block. Its atomic number is 16.
• Its electronic configuration is$1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^4$.
• If it attains a $-2$ charge or gains two electrons. Its electronic configuration will be as follows$1{\mathrm{s}}^{2}2{\mathrm{s}}^{2}2{\mathrm{p}}^{6}3{\mathrm{s}}^{2}3{\mathrm{p}}^6$.
• This electronic configuration is that of Argon which is a noble gas.
• The noble gas configuration is the most stable due to completely filled orbitals.
• Hence, Sulfide has a 2 Charge.
