Each proton and neutron is made up of three quarks.
The mathematical answer to the question what number divided be four equals three is 12.
It equals 3.
From looking at the chart of the nuclides, you can determine that Fluorine has a total of 13 isotopes (F-15 through F-27). Only one of Fluorine's isotopes is stable (F-19) and makes up 100% of the naturally occurring fluorine. The other 12 Fluorine isotopes are all radioactive and have half lives ranging from 5 x 10E-22 seconds (F-15) to 1.83 hours (F-18).
Three isotopes. All have one proton and one electron. Protium has 0 neutron, Deuterium has 1 neutron, Tritium has 2 neutrons.
The three isotopes that commonly undergo neutron-induced fission are uranium-235, plutonium-239, and uranium-233. When bombarded with neutrons, these isotopes can undergo a nuclear reaction in which the nucleus splits into two or more smaller nuclei, releasing a large amount of energy.
The three isotopes of hydrogen are called: hydrogen (1H or H, no neutrons), deuterium (2H or D, one neutron), and tritium (3H or T, two neutrons).They each have their own special name to make it easier to refer to them. They are fairly commonly used in chemistry and physics (especially deuterium).
Three isotopes that can undergo nuclear fission are uranium-235, plutonium-239, and uranium-233. When these isotopes absorb a neutron, they become unstable and split into smaller fragments, releasing energy in the process.
There are many isotopes for uranium, the most abundant of them in nature are:Uranium- 234, having 142 neutron and 92 protonUranium- 235, having 143 neutron and 92 protonUranium- 238, having 146 neutron and 92 protonThe abundance of these three isotopes in natural uranium is:Uranium-234: 0.006 %Uranium-235: 0.720 %Uranium-238: 99.274 %
Si (atom number 14) has three naturally occurring isotopes with mass numbers:28 (92%), 29 (5%), and 30 (3%).They have respetively 14, 15 and 16 neutrons.(This is because 'mass number' minus 'atom number' equals 'neutron number')
Each isotope of hydrogen has 1 proton in the nucleus. The difference between the isotopes lies in the number of neutrons: hydrogen-1 has 0 neutrons, hydrogen-2 (deuterium) has 1 neutron, and hydrogen-3 (tritium) has 2 neutrons.
Isotopes of oxygen differ in the number of neutrons they contain in their nuclei. Oxygen has three naturally occurring isotopes: oxygen-16 (8 neutrons), oxygen-17 (9 neutrons), and oxygen-18 (10 neutrons). The differences in neutron count affect the atomic weight and stability of each isotope.
isotopes are atoms of an element with different #'s of neutrons (these are electrically neutral particles which change the weight of the atom); hydrogen has three isotopes; all three atoms have 1 proton and 1 electron but vary from no neutrons(the most common type of atom or isotope) to atoms with 1 neutron and 2 neutrons.

Fluorine has nine protons in its nucleus, which means it has nine electrons surrounding it to maintain a neutral charge. Each proton and neutron is made up of three quarks, so fluorine would have a total of 27 quarks in its nucleus (3 quarks per proton/neutron x 9 protons = 27 quarks).
