How many protons neutrons and electrons does si-28 have?

Answer 1

Silicon 28 (28Si) has 14 protons, neutrons and electrons.

Answer 2

A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the Atomic Mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.

Answer 3

Atomic mass: 28

Protons:14

Neutrons:14

Electrons:10

To find the neutrons, do the mass number of the element minus the atomic number of the element

Answer 4

14 protons, 14 neutrons and 14 electrons
