Fill in the blank the charge of nonmetal ions formed from groups is equal to the group number minus 8.

The charge of nonmetal ions formed from groups 5, 6 and 7 will be equal to the group number minus 8.

Explanation: The charge on an element is defined as the number of electrons gained or lost by that particular element.

Groups of non-metals are Group 5, Group 6 and Group 7.

Charge on Group 5 = (5 - 8) = -3

Charge on Group 6 = (6 - 8) = -2

Charge on Group 7 = (7 - 8) = -1

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
