What does the atomic number tell us about an atom?
The atomic number tells us how many protons and neutrons are in aa 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
The atomic number tells us how many protons are in the nucleus of an atom or element. It also determines the identity of the element since each element has a unique atomic number. Additionally, the atomic number indirectly provides information about the number of electrons in a neutral atom, as the number of protons and electrons in an atom are equal in order to maintain overall neutrality.
The correct statement is: The atomic number tells us how many protons and electrons are in a neutral atom or element.
