If a neutral atom has 17 electrons, what type of ion will it tend to form? A. cation with charge 1+
B. anion with charge 2-
C. anion with charge 1-
D. cation with charge 1-

C. anion with charge 1-

Explanation:

Atoms of group 17 gain one electron and form anions with a 1− charge; atoms of group 16electrons and form ions with a 2− charge, and so on.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
