WebFeb 1, 2024 · With the help of the periodic table, we can easily see that the atomic number of magnesium is 12. As its atomic number is 12, it has 12 protons, and for neutral magnesium, the number of protons is always equal to the number of electrons i.e. has 12 electrons in its nucleus. Step 2: Write Electron Configuration WebFrom this perspective, the reaction between magnesium and oxygen is written as follows. 2 Mg + O 2 2 [Mg 2+ ] [O 2-] In the course of this reaction, each magnesium atom loses two electrons to form an Mg 2+ ion. Mg Mg 2+ + 2 e - And, each O 2 molecule gains four electrons to form a pair of O 2- ions. O 2 + 4 e - 2 O 2-

WebJun 9, 2014 · A magnesium atom has atomic number 12, so 12 protons in the nucleus and therefore 12 electrons. These are arranged 2 in the innermost (n=1) shell, then 8 in the next (n=2) shell, and the last two in the n=3 shell. Therefore a magnesium atom is [2,8,2] WebApr 8, 2024 · This is because when Mg(s) becomes Mg 2 +, it loses 2 electrons. Since there are 2 Mg on left side, a total of 4 electrons are lost according to the following oxidation half reaction: 2Mg(s) → 2Mg 2 + + 4e −. On the other hand, O 2 was reduced: its oxidation state goes from 0 to -2. Thus, a reduction half-reaction can be written for the O 2 ... WebNov 13, 2024 · The electron configuration of the magnesium ion Mg2+ is similar to Na+, Ne, and Al3+. It is not similar to Ar.
