Question

If only an element's atomic number and weight are provided, what other atomic information can be determined for a neutral atom?(1 point) Responses the number of protons, electrons, and neutrons the number of protons, electrons, and neutrons only the number of protons and neutrons only the number of protons and neutrons only the valence electrons only the valence electrons only the number of protons and electrons

Answer 1

Given an element's atomic number and atomic weight, for a neutral atom, you can determine the number of protons, electrons, and neutrons.

• The atomic number indicates the number of protons and, since the atom is neutral, also the number of electrons.
• To find the number of neutrons, you can use the formula:

\[ \text{Number of Neutrons} = \text{Atomic Weight} - \text{Atomic Number} \]

Therefore, the correct response is "the number of protons, electrons, and neutrons."
