well you see, 1s2 2s2 2p6 3s2 3p6 3d5 4s2 is manganese if it becomes 2+ then it loses 4s2 first so it would now look like 1s2 2s2 2p6 3s2 3p6 3d5 which is manganese 2+ but has the spdf of vanadium
hope im helpful

metals lose electrons to form ions so as to obtain noble gas configuration. for e.g. sodium(Na) has 11 electrons i.e. 1 electron in its valent (last) shell, to attain noble gas configuration sodium loses 1 electron which may be gained by a non-metal to stabilize itself.
No; not if it is an ion. A chlorine atom, for example, has 17 protons and 17 electrons, but a chlorine ion (like when it is in sodium chloride, which is table salt) has 17 protons and 18 electrons. So, if you see an element with 18 electrons, it could be a chlorine ion, an argon atom, or a potassium ion.
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
These particles are the electrons with negative electrical charge.
surely i don't know sodium atom which can be gained 2 electrons but anyway i thought the answer is Na+2
some are made losing lots of yams did you know that
It depends how many electrons are on the outer shell :) eg. one electron on the outer shell = loss one seven electorns on outer shell = gain one
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
We know what we know because we have gained knowledge. Knowledge is gained from going to school and through reading books.

An electron is the subatomic particle that has a negative charge.A proton has a positive charge and neutron has a neutral charge.These three together form all known particles (except hydrogen, that doesn't normally have a neutron). The protons and neutrons form the nuclie. The electrons form shells around it, they are held in place by there attration to the protons. Ions are atoms that have lost or gained electrons. e.g.[Zn]+1is a zinc alom that has gaind an electron.
Light is a wave, like sound waves, electromagnetic waves, x-rays, gamma-rays... It does not contain enery; although (electron configuration and chemstry) when an electron or electrons move from their excited state to their ground state they release energy as photons of light (light). sorry idk how to measure the energy released by the electrons when they move back into their ground state, i suspect you would need to know what it (the element) gained the energy from, how much energy was gained, which element it was, which shell and how many electrons moved to an excited stated or into different subshells. (i don't think scientists have found an accurate way of measuring it)
for oxidation or reduction to occur, electrons have to be involved. Either they are lost or gained, and as you probably know, loosing electrons is defined as oxidation and gaining electrons as reduction. In the two examples you give, the substances have already lost or gained electrons and exist as charged particles in solution; they just switch partners. For example, in the classic definition of neutralization, a base contains ( OH- ) ions and an acid contains ( H+ ) ions. If they combine there are no electrons transferred so no oxidation or reduction takes place, and the remaining ions also combine with no electron shifts. Precipitation reactions are exactly the same except that when certain ions in solution combine,( with no electrons exchanged), the substance formed is insoluble and precipitates.
