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.

If there are two electrons in an atom how many protons would be in the atom?

The atom in a normal state would have two protons to match the two electrons, making the overall charge zero. If the atom is an ion, it would have an mismatched number of protons and electrons, giving it a positive or negative overall charge.

How would you figure the number of protons or electrons in an atom?

The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.

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 many electrons are in an atom with 33 protons and 42 neutrons?

That atom is Arsenic. It would have 33 electrons.

Is it possible to reverse the amount of protons and electrons in an atom?

The number of protons can not be changed in an atom, while the number of electrons can be.

What atom particles would be found in a nucleus of an atom?

Electrons, Protons, and Neutrons.

How many electrons versus protons in an atom?

The number of electrons should = the number of protons.

Does most atoms have more protons than electrons?

no a neutral atom does not have more protons than it does atoms. if it really were neutral it would have the equal amount of electrons and protons. if an atom had more protons than neutrons, it would be a positive atom and vice versa. so to answer this question. NO A NEUTRAL ATOM DOES NOT HAVE MORE PROTONS THAN NEUTRONS.

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

Where are protons and neutrins located?

Protons and Neutrons compose the nucleus of the atom. They are surrounded by a cloud of electrons. If our universe was an atom, the sun would be the nucleus (with protons and neutrons) and the orbiting planets would be the electrons.

In an atom the number of electrons must be the same as the number of?

protons, because the protons are positive and the electrons are negative so to have a neutral atom the protons and electrons must be balanced
