Acarbon atom contains 6 protons, 6
neutrons, and 6 electrons?

Answers

They are both isotopes of the same element because they have the same number of protons but a different number of neutrons.
The first thing you have to do is find the number of mols. That's done in terms of the masses.
mol = mass of sample / molar mass
mol = 0.900 / 12.0
mol = 0.0750 mol Carbon

Next Each mol of carbon contains 6 mol of electrons. 
mol electrons = 6 * mol of carbon 
mol electrons = 6* 0.0750 = 0.450 mol

Next find out how many electrons are in 0.450 mol
1 mol = 6.02 * 10^23 
0.450 mol  = 6.02 * 10^23 * 0.45 = 2.71 * 10^23 electrons

Finally find the charge in coulombs
1 electron has a charge of 1.60 * 10 ^- 19
2.71 * 10^23 electrons have a charge of 1.6*10^-19 * 2.71*10^23
The answer is 43360 Coulombs = 4.34 * 10^4 coulombs. 

I have deliberately not used textbook formulas because each textbook has its own format.
The Carbon atom contains exactly 6 protons and 6 electrons
It must gain an electron because if the proton number was to change it would no longer be the same element.
An atom that has 6 protons is a carbon atom. The number of electrons that are surrounding the nucleus determines whether it is electrically charged or if it's electrically neutral.

-57792 C

Explanation:

Recall that in one mole of a substance there are an Avogadro number of molecules. That is:

6.02\,\,\,10^{23}  molecules

therefore, in 1.2 g, there would be ten times less molecules than in the 12.0 g mole, that is:  6.02\,\,\,10^{22}  molecules.

Now, each C there are 6 negative charges, then, the number of electrons will be six times the number of C molecules, that is:  

6\,*\,6.02\,\,\,10^{23}=36.12\,\,\,10^{22} =3.612\,\,\,10^{23}  electrons.

Now we multiply this number times the charge of an electron (1.6\,\,\,10^{-19}\,C), and we obtained the total negative charge of the carbon sample:

Total negative charge is: 5.7792\,\,10^{4}\,C=57792\,\,C

therefore the total negative charge is: -57792 C

6 protons would be Carbon, C

yes.

Explanation:

carbon contains 6 protons, 6 electrons as well as 6 neutrons

Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
