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

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
