Answer:
H2S.
Explanation:
Ions may be defined as the element that contains either positive or negative charge over them. Two types of ions are cations and anions. The outermost electrons are involved in the formation of ions.
The atomic number of sulfur is 16. Its outermost electronic configuration is K=2, L= 8, M= 6. The sulfur requres two more electrons to complete its orbit and accquire -2 charge.
H S
+1 -2
Then, the formula will be H2S.
Thus, the correct answer is option (c).
