Handy mnemonic: “LEO goes GER”: Lose Electrons, Oxidized; Gain Electrons, Reduced.Every subshell has a # of orbits s/p/d/f that can each hold 2 electrons each (one has the opposite spin of the other). The first shell (of all atoms) has 1 subshell of s-orbitals containing 1 s orbital. This means that the first shell can hold 2 electrons. The second shell has 2 subshells: 1 s-orbital and 3 p-orbitals.The loss of electrons is also accompanied by the loss of energy. Electrons are gained during the reduction of carbon dioxide to methane. The gain of an electron is accompanied by a gain in potential energy and often by the addition of a proton (H +). Credit: Ryan, K., Rao, A.and Fletcher, S. Department of Biology, Texas A&M University. ...This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius. Atomic radius increases from top to bottom within a group. This is caused by electron shielding.In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet.

COVID hair loss is also a common symptom observed. While hair loss might be a concerning side effect, it can usually be reversed.Atoms are neutral, which means there is an equal number of protons and electrons. Ions are atoms WITH a charge. The charge can be positive or negative. In other words, the atom gains or loses an electron. The proton never changes (if the proton changes, it is a different element)! See here for Sal's explanation: 2:00.The electrons that are lost in the oxidation reaction are the same electrons that are gained in the reduction reaction.
