Given information
Here, K (potassium) is a nonmetal with a valence electron 1
S (Sulfur) is a metal with a valence electron 6
when nonmetal (Sulfur) reacts with metal (potassium) there forms an ionic bond hence (potassium sulfide) is an ionic compound.
is having a total 8 valence electron
Sulfur gets electrons from Potassium to complete the octet. hence K develops + charge on it and S have 2- negative charge.
Step-by-step explanation
Step 1.
when nonmetal (Sulfur) reacts with metal (potassium) there forms an ionic bond hence (potassium sulfide) is an ionic compound.
