Isotopes of the same element have different numbers of what. a. Protons b. Neutrons. c. Neutrons and electrons d. Protons and electrons

b. Neutrons

Explanation:

Isotopes of the same element have different number of neutrons. The number of neutrons is the determinant of an isotope.

Isotopes of an element have the same electronic configuration hence they have the same chemical properties.

Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of neutrons in their various nuclei.

The number of neutrons makes the difference in isotopes.

it means there are 3 atoms of oxygen

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
