They lose energy,which is then used by the cell to make ATP
Excited electrons are transferred to an electron transport chain.
most become reactants in the electron transport chain
Electron chain transport is a series of redox reactions involving proteins embedded in the inner mitochondrial membrane. During this process, electrons are passed along a chain of protein complexes (such as complexes I, II, III, and IV) to generate a proton gradient used to synthesize ATP through oxidative phosphorylation. This is a crucial step in cellular respiration for producing energy in the form of ATP.
the number of valence electrons increases on moving from left to right in periodic table.Group 1 has 1 valence electron and group-18 has 8 valence electrons.
Transport Tycoon happened in 1994.

It loses a negative charge and then becomes a positive ion
A calcium atom must lose 2 electrons to achieve a noble gas structure, as it will then have the same electron configuration as argon, a noble gas. This loss of electrons allows the calcium atom to have a full outermost electron shell, giving it greater stability.
When an atom gains one or more electrons to form a negative ion, its size generally increases. This is because the additional electrons cause greater repulsion between the electrons, resulting in an increase in the overall size of the atom.
Not entirely sure what the point of the question is, but here are two of the relations between the charge of the electron and electron flow in a circuit; I hope this helps.1. The electron has a negative charge. This is an accident of history; there's really nothing fundamentally "negative" about the electron charge, it's just that some some particles have one kind of charge and others have an opposite one, and the the sign of the charge was assigned before electrons had really been discovered. The choice was arbitrary and could have gone either way, but electrons just happened to end up negative. You can blame Ben Franklin for it. But I digress.Electric current is defined as flowing from positive to negative. If the mobile charge carriers are positively charged, then they are flowing in the same direction as the current. But if the mobile charge carriers are negative - like electrons, which are the carriers in metals - then the carriers are flowing in the opposite direction from the current. In other words, the electrons flow "backwards" because they are negative, because Ben Franklin just happened to write '+' and '-' in the "wrong" places (though he couldn't possibly have known.)2. The electron charge is -1.6×10-19 Coulombs. To put that another way, one Coulomb is about 6.24×1018 electrons worth of charge. Since one Ampere is the flow of one Coulomb of charge per second, it is also a flow rate of 6.24×1018 electrons per second. That's more than six billion billion electrons each second for each Ampere!
It becomes a positive ion.
