The uranium atom is electric neutral; uranium cations exist from 2+ to 6+.
(Atomic number) - (Number of electrons present) = (overall electrical charge of atom)
I believe you use a periodic table to find the specific element you're looking for.
92 protons.
Those are electrons, and they have a charge of minus 1.
Electrons are found outside the nucleus of the atom and they have negative charge.
Yes - in any atom, you will find protons (+ charge) and neutrons (neutral or 0 charge) in the atom's nucleus. You will find the electrons (- charge) outside the nucleus in the electron cloud.
Knowing which element it is and its formal charge, subtract the charge from its atomic number.
By definition, every atom of every element must have the same number of protons as every atom of that same element. So, all you have to do is find which element has 35 protons. Look at the periodic table, and find the 35th listed element. That element is Bromine. So Bromine is the correct answer.
It would have 4 protons.
Among the elements that occur in nature, it's Uranium, with 92 protons in the nucleus. Small amounts of atoms with higher atomic numbers are produced in particle accelerators. Their nuclei are unstable, and break down into nuclei with lower atomic numbers.
You can't. To find the mass number, you need to know how many neutrons are in the nucleus (mass number = # of protons + # of neutrons). The atomic number is equal to the number of protons, and the charge tells you the number of electrons indirectly (net charge of atom = # of protons – # of electrons). Neither of these things tells you anything about the number of neutrons, which is what you need.See the Related Questions to the left for more information.
in an atom of neutral charge, the number of electrons will be the same as the number of protons, or the atomic number.
