The position of Carbon on the Periodic Table tells you how many protons carbon has in its nucleus. The number after it tells you the total number of protons and neutrons. You can take the number after it and subtract its number on the periodic table and get the number of neutrons.
For example: Helium is the second element in the periodic table. Helium 3 has two protons and one neutron. Helium 4 has 2 protons and 2 neutrons. Since it is element number 2 it has two protons.
Now try that with carbon.
mass number - atomic number = number of neutrons
Mass number of carbon-14 is 14. The atomic number of carbon is 6.
Calculation:
14 - 6 = 8 neutrons.
Eight neutrons.
A carbon-14 atom has 8 neutrons.
Carbon 14 has 8 neutrons.
12
8 neutrons
To be a carbon atom or ion, it must contain 6 protons. There may be either 6, 7 or 8 neutrons along with the protons in the nucleus.
The Bromine atom contains: 35 protons, 35 electrons, and 45 neutrons.
Protons: 5 Neutrons: 7 Electrons: 5
The most stable isotope of sulfur (S-32) has 16 electrons, 16 protons and 16 neutrons.
There are 16 protons, 16 neutrons and 16 electrons in a Sulfur atom. *note it's atomic number- this is the number of protons in an atom of an element. There must be the same number of electrons to balance the charge. The atomic weight minus the number of protons gives you the number of neutrons
7 protons, 7 neutrons and 7 electrons
Each atom has a unique combination of protons, neutrons, and electrons.
117 neutrons in Pt-195 isotope.
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
4 A+
a neon atom has 10 electrons , 10 protons , and 10 neutrons. its mass no. is 20 and atomic no. is 10. it is a stable atom.
A typical atom of iodine contains 74 neutrons.
Each element has a different number of protons and neutrons. So it changes for each element.
11 neutrons
45 neutrons
there are 7 neutrons because when you take away the number of protons, which is 7 as well, from the atomic mass, which is 14 when rounded, you get 7 which is the number of neutrons in nitrogen.
