carbon (c) is one of the most abundant elements on earth and is a critical element in the molecules that make up living things. carbons atomic number is 6 and its atomic mass is 12. this means that carbon has protons, electrons, and neutrons.
6 12

Explanation:

Step1: Recall atomic number property

The atomic number is equal to the number of protons. Since carbon's atomic number is 6, the number of protons is 6.

Step2: Recall electron - proton relationship

In a neutral atom, the number of electrons is equal to the number of protons. So carbon has 6 electrons.

Step3: Calculate number of neutrons

The atomic mass is the sum of protons and neutrons. Given atomic mass = 12 and number of protons = 6. Let the number of neutrons be $n$. Then $12=6 + n$, so $n=12 - 6=6$.

Answer:

6 protons, 6 electrons, 6 neutrons
