The formula for potassium sulfide.
Answer to Problem 14PP
The formula for potassium sulfur is
Explanation of Solution
Given:
The compound ispotassium sulfide.
Calculation:
Potassium sulfide consists of two elements that means potassium and sulfur. Potassium belongs to group 1 and it has 1 electron in the outermost shell. Sulfur belongs to the group of 16 and it has 6 electrons in the outermost shell.
Potassium loses its outermost electron to attain noble gas configuration and oxygen needs 2 electrons to attain noble gas configuration. The electronic configuration of potassium is 2.8.8.1 and sulfur is 2.8.6. The charge of potassium is +1 and sulfur is -2.
Cross multiply the charges and the formula for potassium sulfur is obtained as
Conclusion:
Thus, the formula for potassium sulfur is
