How many protons electrons and neutrons are in a carbon 12 atom?

Answer 1

Answer Firstly, all carbon atoms have only 6 protons. Most of them have 6 neutrons (giving an atomic weight of 12 a.m.u.). Some have 8 neutrons (giving an atomic weight of 14 a.m.u.). These atoms are called isotopes. They are the same chemical element, and react the same in chemical reactions, but the different numbers of neutrons make them slightly different. When atoms of the same element appear with different numbers of neutrons in the nuclei, we call the variations on the theme isotopes of that element.

Answer 2

The answer is 6 protons and 6 neutrons (and 6 electrons)

• p = proton number (specific for one particular element) = atom number (= also equal to the number of electrons of the neutral element)

• n = neutron number (is different for each particular isotope of an element)

• m = mass number = p + n = total of protons and neutrons = about the actual mass of (one particular isotope) an element

Carbon-12: atom number 6 and isotope mass number 12:

p = 6, m = 12, so n = m-p = 6

==> the answer is 6 protons and 6 neutrons (and 6 electrons)

Answer 3

The atomic number of carbon is 6; this is also the number of protons in carbon-12, and to maintain electrical neutrality, the number of electrons is also 6. The mass number, 12, is defined as the sum of the numbers of protons and neutrons; therefore, the number of neutrons in carbon-12 is (12 - 6) or 6.

Answer 4

Carbon-12 and Carbon-14 are isotopes of carbon. Carbon-14 is radioactive and used in C-14 dating.

Answer 5

Carbon-12 has 6 protons, 6 neutrons, and 6 electrons.

Answer 6

The isotope carbon 12 has 6 protons, neutrons, electrons.

Answer 7

6 protons and 6 neutrons

Answer 8

Every carbon atom has 6 protons.

Answer 9

six
