Acarbon-12 atom has 6 protons, 6 neutrons, and 6 electrons. how many protons does a carbon-14 atom have?
a. 6
b. 8
c. 12
d. 14

Option (a) is the correct answer.

Explanation:

As the given atom is so, it means that it contains 6 protons. Also, when an atom is neutral then its number of protons equal to the number of electrons.

Atomic mass means the sum of total number of protons and neutrons present in an atom. As is an isotope of . And, all the isotopes of carbon or any other element contains the same number of protons but different number of neutrons.

Therefore, there will be 6 protons present in .

Thus, we can conclude that carbon-14 atom have 6 protons.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
