What does the atomic number tell us about an atom? * 1 point

Question

The atomic number tells us how many protons and neutrons are in a neutral atom or element

The atomic number tells us how many protons and electrons are in a neutral atom or element

The atomic number tells us the mass of the atom or element

Answer 1

The correct answer is:

The atomic number tells us how many protons and electrons are in a neutral atom or element.

In a neutral atom, the number of protons is equal to the number of electrons, which is also the atomic number. The atomic number does not directly indicate the number of neutrons, as that varies among isotopes of an element.
