Answer:

Number of Protons

• 14

• 6

• 26

• 17

• 82

Number of Neutrons

• 14

• 6

• 30
• 18

• 125

Number of Electrons

• 14

• 6

• 26

• 17

• 82

Explanation:

The nuclide of an isotope of an element is

where:

• A = mass number = number of protons + number of neutrons

• Z = atomic number = number of protons = number of electrons (if neutral)

• X = element symbol

• N = number of neutrons = A - Z

The nuclide of an isotope of an element is

{{A}\atop{Z}}X

Z

A

X

where:

A = mass number = number of protons + number of neutrons

Z = atomic number = number of protons = number of electrons (if neutral)

X = element symbol

N = number of neutrons = A - Z
