A student makes the following statement about neutral atoms while gathering information for a presentation:

"Atoms a neutral at ground state since they have equal numbers of protons and neutrons."
Help this classmate clarify the statement by selecting a better response.
A. Atoms are neutral at ground state since they have equal numbers of protons (+) and electrons (-) for each element type
B. Atoms are not neutral at ground state at all.
C. Atoms are neutral at ground state since they have equal numbers of electrons (-) and neutrons (0).

1 answer

The best response to help clarify the statement is:

A. Atoms are neutral at ground state since they have equal numbers of protons (+) and electrons (-) for each element type.

This response correctly explains that atoms are neutral because the positive charge of protons is balanced by the negative charge of electrons. Neutrons do not affect the charge of the atom.
