All atoms are a) positively charged, with the number of protons exceeding the number of electrons.
b) negatively charged, with the number of electrons exceeding the number of protons.
c) neutral, with the number of protons equaling the number of electrons.
d) neutral, with the number of protons equaling the number of electrons, which is
equal to the number of neutrons.

c) neutral, with the number of protons equaling the number of electrons.

Explanation:

Every atom is neutral. This is because they contain equal numbers of positive protons and negative electrons. Atoms, in which the number of electrons is not equal to the number of protons, are called ions. Ions can occur from ionic bonds in which two elements take and give electrons in order to fill their outer shell and become stable. The action of taking and giving electrons between atoms leaves those atoms to be either negatively charge( The atom has more electrons than protons) or positively charged (The atom has more less electrons than protons).

i think   the answer is c hope i'm right
