If you have an isotope of Uranium, Uranium-237, how many protons neutrons and electrons does it have.?
969429
92 protons and 92 electrons\nIsotopes have a different number of electrons

Lithium has four neutrons and three protons. The number of protons is determined by the Atomic Number, which is the number at the upper left of the periodic table. Using the nearest whole number of the atomic weight, which is the numerical average of the relative proportions of the isotopes, and subtracting the atomic number, the number of neutrons is determined. For lithium with an atomic weight of 6.941, or about 7, the number of neutrons is 7 - 3 = 4. P. S. I referred to my Periodic Table of the Elements, not the web for my answer. I do not normally search the web for my answers.

In a stable atom, not an ion, the # of electrons equals the # of protons, so potassium would have 19 protons, and 19 electrons.  Protons and Neutrons make up the atomic weight of the atom, so you take the atomic weight and subtract the atomic # and you are left with # of neutrons.  39.0938-19=20 because you round, you can't have a fraction of a neutron.  Therefore, there are 20 neutrons, 19 electrons, and 19 protons.

You can figure it out.\n\nIf a neutral atom of zinc has an atomic number of 30, and a mass number of 65, then it has 30 protons, 35 neutrons, and 30 electrons.\n\nProtons and neutrons are found in the nucleus.\nSo, draw a circle. Write "30p+" and "35 n" inside it.\nThis represents the nucleus.\n\nIn Bohr's model, electrons orbit the nucleus at specific energy levels. The first level holds up to 2 electrons.\nThe second holds up to 8.\nThe third holds up to 8.\nThe fourth holds up to 18.\nWe use dots to represent electrons.\n\nDraw a ring around the nucleus.\nAdd two dots to the ring, usually at noon and 6:00.\n\nDraw another ring around the first one.  Draw eight dots: two at noon, two at 3:00, two at 6:00, and two at 9:00.\n\nContinue adding rings and electrons.\nYou should end up with twelve dots in the outermost ring.\n\n(Which doesn't correspond with the  Lewis diagram for zinc, but that's  another story....)

Protons is the atom's atomic number.  It gives the atom its certain "chemical properties".  The proton has a weight of 1.  The neutron is a combination of a proton and electron roughly as evidenced by storing a neutron for more then 15 min and it will turn into a hydrogen atom.  For all intensive purposes the electron has no weight.  The neutron weighs 1 as well. When you combine the numbers of protons and neutrons in an atom you get the weight.  The neutrons act as glue for the atom and help keep it together.  Thus Uranium 235 is more unstable then Uranium 238. (235 is what they use in reactors).  The electron is attracted to the proton. Electron(-) proton (+).  But as you get towards the left section of the table you have atoms that want to lose their electrons since the want full orbitals.  As you get toward the right side of the table you get atoms that want to gain electrons to fill their shells.  These atoms that have a positive charge are known as cations longer word = positive. Shorter word or Ion = negative.

The atomic number of gallium is 31. Therefore, there is 31 protons and 31 electrons. However, The mass number of gallium can be varied because gallium contains isotpes. Each isotope has the same atomic number but different mass number. The most abundance isotope of gallium has a mass number of 70. So there is (70 - 31) = 39 neutrons.

neutron\n\nhowever, it is already an isotope, changing the neutrons would make it a different isotope\n\nchanging the protons would change the element\nchanging the electrons would change the charge

the atomic number is 5 b/c atomic number equals the number of elctrons and protons. You have 5 electrons so it should be 5.

If there are no neutrons in the nucleus, there can be only one proton. If there were two or more protons, they would not stay together to form a nucleus without any neutrons.\n\nAnd of course an atom with only one proton in its nucleus is hydrogen.

Well if it's stable, there will be the same amount of protons as electrons. If it has a charge add or subtract. \n(If you have a plus charge, that means there's 1 more proton than electron... if you have a -2 there are two more electrons than protons etc.)

I believe the answer is Osmium. He is asking for number of neutrons, not number of protons. Take the atomic mass, (Os = 190.23) And subtract the number of protons it has (Os = 76), giving you an answer of 114.

The number of protons in the fission product must be 92-55 = 37.  The number of neutrons must be 1+235-143-3 = 90.  Look up in the periodic table to see what element 37 is. It is virtually certain that 90 neutrons are too many for stability, and the product will be a beta emitter.
