21 times 3 equals 63
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.
Three isotopes. All have one proton and one electron. Protium has 0 neutron, Deuterium has 1 neutron, Tritium has 2 neutrons.
They are many but the most famous three are: uranium-233, Uranium-235, and Plutonium-239.Another answerUranium-235, uranium-238, and plutonium-239 are all capable of undergoing neutron induced fission. Actually there are other isotopes that also do this, but they are not commonly used as fuel.
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).
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 %
There are many isotopes, especially of the trans-Uranium elements which can undergo nuclear fission. The isotopes which are used in nuclear reactors are Uranium-233, Uranium-235 and Plutonium-239, because these isotopes are more readily available than other fissionable isotopes. Uranium-235 occurs naturally, Uranium-233 can be made by neutron irradiation of Thorium-232 and Plutonium-239 can be made by neutron irradiation of Uranium-238.
There are three known naturally occurring isotopes of hydrogen; hydrogen-1 with one proton and no neutrons, hydrogen-2 with one proton and one neutron, and hydrogen-3 with one proton and two neutrons.
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')
By definition Hydrogen has only one proton.
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.

There are three natural isotopes.
No the atomic number is same for the three isotopes of hydrogen (it is 1). The three isotopes of hydrogen differ by the number of neutrons.
