How many neutrons does carbon-17 have?

Answer 1

11

Carbon has atomic(proton) number 6. i.e it has 6 protons.

There are three naturally occurring isotopes for carbon.

They are C12 c13 and c14. among them c14 is radioactive.

c12 has 6 protons and 6 neutrons.

c13 has 6 protons and 7 neutrons.

c14 has 6 protons and 8 neutrons.

Similarly, c17 has 6 protons and 11 neutrons.

Answer 2

The atomic number of carbon is 6. So it will always have 6 protons, irrespective of the isotope under consideration.

Answer 3

Well, since carbon always has 6 protons (otherwise, it isn't carbon), Carbon-16 will have 10 neutrons to total the isotope's Atomic Mass of 16.
