Magnesium has 12 electrons.........which wud mean that in the 1st energy level(n=1) there r 2 electrons, in the 2nd energy level(n=2) there r 8 electrons and in the 3rd energy level(n=3) there r 2 electrons.......its simple......use the formula 2n^2 where n= 1,2,3,......
so the electron configuration of Magnesium in 2,8,2..................or more precisely 1s2, 2s2, 2p6, 3s2
Answer:
Acids
Explanation:
Acids are ionic compounds that produce positive hydrogen ions when dissolved in water. Acids taste sour. They conduct electricity when dissolved in water. They also react with metals to produce hydrogen gas.
In light reactions, a molecule of chlorophyll absorbs one photon of light, causing a chlorophyll electron to transfer to a higher energy level. ... Chlorophyll then replaces the lost electrons from water molecules. The oxygen atoms form oxygen gas while the hydrogen atoms form protons and electrons.
