GEOLOGY

Detailed explanation-1: -Which one has a positive charge, a negative charge, and no charge? Proton-positive; electron-negative; neutron-no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.

Detailed explanation-2: -An ion is an atom or group of atoms that has an electric charge. Ions with a positive charge are called cations. Ions with a negative charge are called anions.

Detailed explanation-3: -Positively charged ions are called cations; negatively charged ions, anions.

Detailed explanation-4: -Protons are positively charged and electrons are negatively charged while neutrons have no charge.

Detailed explanation-5: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge.
