Question

The atomic number of an element X is 30 and the mass number is 65. Find the number of protons, neutrons, and electrons in an atom of element X.

Answer 1

Answer:

protons-30 neutrons-35 electrons-30

Explanation:

the atomic number and number of protons is always the same, the neutrons is the mass-protons, and the electrons are the same number of protons unless there is a charge stated (ex. -2 charge add 2 more electrons to proton number) also I hope you know that you subtract cations and add anions
