Yes it does - from the oxygen atom as well as it's own.
It is an oxidation/reduction reaction. The metal loses electrons to become positively charged (it is oxidized) and the oxygen gains those electrons to become negatively charged (it is reduced). You end up with a metal oxide.
Metals are oxidized, ie they lose electrons. An oxidized metal will bond with another element. The roman numerals signify how many electrons the metal lost which is called an oxidation number.
Oxidation involve loss of electrons and reduction involve gain of electrons.
Well it has less electrons than it had before. That is the definition of oxidation. The loss of electrons is oxidation. The gain of electrons is reduction.
Actually, non metals always gain electrons
They need to gain them.
Oxidation is the loss of electrons. Reduction is the gain of electrons. The oxidizing agent is reduced. The reducing agent is oxidized. Cu goes from 0 to +2, it lost electrons S went from +6 to +4, it gained electrons I went from 0 to +5, it lost electrons N went from +5 to +4, it gained electrons.
This is called a redox reaction, where one molecule gains electrons and one molecule loses electrons. Reduction is the gain of electrons and oxidation the gain of electrons. It can be remembered as OILRIG (Oxidation Is Loss Reduction Is Gain).
It loses electrons LEO the lion says GER Loss of Electrons = oxidation, Gain of Electrons = Reduction Loss of Gain of electrons Reduction electrons oxidation (leo)
A reducer or reducing agent is something that can lose electrons and be oxidized so that another compound can gain electrons and become reduced. For example: glycerol can be oxidized to glyceraldehyde allowing for NAD+ to be reduced to NADH.
This is a metal so it will lose its valence electrons.
No gain of electron is reduction. An atom that gains electrons is reduced in a chemical reaction. OIL RIG; oxidation is loss, reduction is gain
