How many neutrons will an atom have it has an atomic number of 26, an atomic mass of 58 and a charge of +3?

Recall that both 1 proton and 1 neutron each have a mass of 1 amu. (Electrons have a mass on the order of 10⁻⁴ amu so we can effectively ignore it.)

Now,

atomic number = number of protons = 26

hence the protons have a total mass of 26 amu. The atomic mass is the sum of the masses of protons and neutrons, so

atomic mass = mass of protons + mass of neutrons

mass of neutrons = 58 - 26

mass of neutrons = 26

and again, each neutron has a mass of 1 amu. So there are 26 neutrons in the nucleus of this atom.

Don't let the extra positive charge fool you; both the atomic number and mass are fixed, so the discrepancy must be due to the absence of 3 electrons.

scientific laws are the result of testing theories and proving them to be facts.

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
