Oxidation occurs when electrons are lost by an atom while reduction refers to the gain of electrons by an atom.
<u><em>In this case, magnesium atom reacts with sulfur to form magnesium sulfide by loosing two electrons and forming magnesium ion (Mg2+). Therefore magnesium undergoes oxidation.</em></u>
Sulfur, on the other hand will gain electrons to form Sulfide ions, therefore it undergoes reduction.
Therefore;<em><u> In magnesium sulfide (MgS), magnesium loses two electrons and becomes a cation with a positive-two charge. Likewise, sulfur obtains the two electrons lost from magnesium and becomes an anion with a negative-two charge. However, the overall charge of MgS is zero.</u></em>
Draw eight circles and nine more in a big circle = this represents your nucleus draw eight electrons (since electrons = protons in neutral elements) outside of it (2 in one ring, then 6 in a second ring)
1.Scientists use a shared system for reporting measurements called the International System of Units (SI). We use common measurement systems because science involves a lot of replication to confirm results. The most common system used in science is the metric system.
