This is Carbon-12 (12C) it has a mass of exactly 12 universal Atomic Mass units. It serves as the standard for the universal atomic mass scale.
If you look up carbon on the Periodic Table, you will find that it says 12.011. This difference is because a small amount of carbon has a seventh neutron, which is averaged into the atomic weight given on a periodic table.

Why do most atoms have the same number of protons and electrons?
So the atom is neutral, if an atom had more protons than electrons, then the atom would have a positive charge, and if it had more electrons, then it would have a negative charge,if atoms had a charge, we would get shocked every time we touch something
What has to be true about the protons and the electrons on an atom that is neutrral?
In any atom,there are protons, neutrons and electrons. As the name would suggest, neutrons carry no charge. Protons carry a positive charge and electrons carry a negative charge. So in an atom that has no charge there has to be an equal number of protons and electrons.
How would you describe an atom in which the number of protons is equal to the number of electrons?
An atom in which the number of protons is equal to the number of electrons is considered to be electrically neutral. This balance between positive protons and negative electrons results in no overall charge on the atom.
What would the charge of an atom be if it has six protons and six electrons-?
Zero, the atom would be electrostatically neutral.. the 6 positive charges of the protons are cancelled out by the 6 negatives of the electrons
What is the atom with the most electrons than protons is called?
An atom with more electrons than protons is called an anion. This creates a negative charge in the atom due to the excess electrons.
