What does an atom consist of? Hydrogen is reduced in the reaction. Gaining or losing electrons has no impact on the number of protons and neutrons an atom has, which is another way of saying that the mass number is not affected by changes in the net charge. What happens when you lose one electron? Moonlight is reflected light from the earth or sun? If it gains an extra electron, it Describe protons. When electrons are lost by one atom, they must be gained by another element. Similarly, reduction and oxidation can be defined in terms of the gain or loss of hydrogen atoms. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Valence electron If the lone pair of electrons belongs to an oxygen atom of a water molecule, the result is the hydronium ion (H 3 O +). If a neutral atom gains an electron, it becomes negative. Its called nuclear fusion and basically involves mashing protons and neutrons together to form new atoms some hydrogen, some helium, some lithium, etc, all the way up to iron.
