To isolate a single variable when re-arranging equations, move all other variables to theof the equation by using theon them and remembering to perform that operation. Make sure the rearrangement has the target variable. a. on the left side, not the right side.
b. in the numerator, not the denominator.
c. with a coefficient, not without one.
d. with a negative sign, not a positive sign.

Other side

Opposite function

On both sides of the equation

In the numerator and not the denominator

Explanation:

To isolate a single variable when rearranging equations, move all other variables to the other side of the equation by using the opposite function on them and remembering to perform that operation on both sides of the equation. Make sure the rearrangement has the target variable in the numerator, not the denominator.

explanation:

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
