EleoNora [17]

Answer:

a) 50 protons, 50 electrons, 75 neutrons

Explanation:

How many protons, electrons, and neutrons does an atom with atomic number 50 and a mass number of 125 contain?

a) 50 protons, 50 electrons, 75 trons

b) 75 electrons, 50 protons, 50 neutrons

c) 120 neutrons, 50 protons, 75 electrons

atomic number IS the number of protons

atomic mass IS the total of protons + neutrons

so 50 protons

125-50 = 75 neutrons

in a neutral atom,

number of negative electrons = number of positive protons

a) 50 protons, 50 electrons, 75 neutrons
