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?
You could describe it as neutral as the charge of the protons cancels out the charge of the electrons, essentially though it is just a normal atom as if the number of protons was different to the number of electrons, it would be classed as an ion.
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?
If you mean an atom with more electrons than protons it is called an ion. More specifically an anion (negatively charged)
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 many electrons would a neutral atom of cadmium have?
The neutral atom of cadmium has 48 electrons.
How many electrons will a neutral atom have when it has 12 protons?
A neutral atom with 12 protons will have 12 electrons in order to balance the positive charge from the protons.
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
An element has an atomic number of 30 how many protons and electrons are in a neutral atom of the element?
It will have 30 protons and 30 electrons if the atom is neutral.
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 would you expect to find in a neutral atom containing three protons and four neutrons?
In a neutral atom, the number of electrons is equal to the number of protons. So, in an atom with three protons, it would contain three electrons. The number of neutrons does not affect the charge or number of electrons in the atom.
How many electrons are in an atom with 33 protons and 42 neutrons?
That atom is Arsenic. It would have 33 electrons.
If an atom has 19 protons and 20 neutrons how many electrons would it have?
Electrons carry a negative charge and protons carry a positive charge. Therefore, if an atom is to be neutral it must have equal numbers of protons and neutrons. Consequently, if an atom has 19 protons and is neutral it must have 19 electrons.
What atom particles would be found in a nucleus of an atom?
Electrons, Protons, and Neutrons.
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 if their are 8 protons in an atom how many electrons are their?
If it is neutral, there would be equal protons and electrons. However, if it is a charged ion, then there could be more or less electrons than protons. For example, 8 protons and 7 electrons would give +1 charge. 8 protons and 10 electrons would give -2 charge. Each proton has a +1 charge. Each electron has -1 charge.
