Which of the following best describes the definition of an ion? A. An atom with a neutral charge
B. An element that has an unequal number of protons and neutrons
C. An element that has unequal number of protons and electrons
D. An element that has unequal number of electrons and neutrons

A

Explanation:

An ion is a particle, atom or molecule with a net electrical charge.

C. An element that has an unequal number of protons and electrons

Explanation:

An element has an equal number of protons and electrons, because the positive and negative energy has to cancel out so the atom is neutral. Ions are versions of atoms that lose electrons so they have a different energy than the initial atom, but they're still that atom because the number of protons determines the identity of the atom, and that number doesn't change.

asking the goog might u get an answer

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
