An ion has a charge of +7. how far is it from being neutral? a. -0.07 b. -7 c. 7 d. 70 e. 0.7

We are given that

An ion has a charge of +7

and a neutral has charge always 0

so, change is charge = ion charge - neutral change

so, we can plug values

change is charge = +7 -0

change is charge = 7

so, option-CAnswer

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
