Question

how many protons, electrons, and neutrons are in the following isotopes.
uranium-235
hydrogen-3
silicon-29

Answer 1

The number of protons is the atomic number.
The mass number is the number of protons + the number of neutrons.
The number of electrons is the same as the number of protons(in a neutral element).

Answer 2

so for uranium would it be
protons 92
electrons 145
neutrons 145

Answer 3

Did you read what I wrote?
The number of protons is the atomic number. 92 is correct.
The number of electrons <b>is the same as the number of protons</b> which must be 92.
The number of neutrons is mass number-atomic number = 235-92=143.
