92 protons and 92 electrons
Isotopes have a different number of electrons

An isotope contains the same number of protons just more or less neutrons.
The atomic number is the number of protons you have and the top number in this case (237) is the number of protons and neutrons added together
So to find out how many protons you have you use the atomic number hence its 92 protons.
And we know that there are the same number of protons as their are of electrons so you have 92 electrons.
Now to find the number of neutrons you just simpliy subtract 237 by 92 to get 145 neutrons
Protons = 92
Electrons = 92
Neutrons = 145

Uranium is atomic number 92 - this means it has 92 protons - which in a neutral atom means it also has 92 electrons. 235 and 238 are the mass numbers (or nucleon number) of two of its isotopes. The neutron number = the mass number - the atomic(proton) number. So just subtract 92 from both 235 and 238 to get your answer.

First, the number of electrons would be 92, this is gotten from the atomic number of uranium which is 92 (the number of electrons of an element equals it's atomic number), then the number of protons would be 92 (the number of protons equals the number of electrons) and finally the number of neutrons is gotten by subtracting the mass number which is 237 here from the number of protons which is 92 to have 145 has your number of neutrons.
protons=92
electrons=92
neutrons=237-92=145
