Question

if an atom has five protons and four electrons, the atom is
neutral.
radioactive.
negatively charged.
positively charged.

Explanation:

Protons have a positive charge (+1) and electrons have a negative charge (-1). An atom is neutral when the number of protons equals the number of electrons. Here, there are 5 protons and 4 electrons. The net charge is \(5\times( + 1)+4\times(-1)=5 - 4=+1\).

Answer:

D. positively charged
