Mass no-the no of proton=no of neutron
Carbon-7 is a theoretical isotope that does not actually exist. But if it DID exist, it would have one neutron, because the mass number of any isotope = protons + neutrons, and all carbon atoms have 6 protons. Therefore C-7 would have 6 protons and one neutron.
Carbon-14 has 6 protons and 8 neutrons. The mass of one neutron is approximately 1.0086649 atomic mass units (u). Therefore, the total mass of neutrons in 7 mg of Carbon-14 can be calculated by multiplying the number of neutrons (8) by the mass of one neutron to get approximately 8.0693192 mg.
mass number= no. of protons + no. of neutron
One neutron is approximately equal in mass to one proton. Since an electron is much smaller in mass compared to a neutron or a proton, it would take a large number of electrons to equal the mass of one neutron.
You calculate the number of neutron in the nucleus of an atom by : atomic mass - atomic number = neutron number. :) hope this helps
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 104
It is not possible.
there is amount of proton = amount of electron and the mass = amount of proton + amount of neutron so we take the mass - amount of pronton we will get the amount of neutron =20.8
Mass number is simple the #(number) of protons plus # of neutrons. Looking at the periodic table we can see that carbon contains 6 protons. Therefor we simple subtract 6 from 14, that is, 14 - 6 = 8 There are 8 neutrons in this isotope.
6. Carbon's atomic number is 6, meaning it has 6 protons and 6 neutrons. Carbon-14 has a mass number of 14, meaning it has extra neutrons, but no extra protons. So Carbon 14 still has 6 protons, and it has 8 (14-6) neutrons.
Atomic mass is the number of protons and neutrons that make up an atom. The neutron number is only the number of neutrons present in the atom. This can be found by subtracting the number of protons from the atomic mass.
