Web1 Answer. For the first part of your question, you are correct that Mg has 12 electrons, which are arranged in shells in the pattern 2 - 8 - 2. But magnesium is a typical metal in that it tends to lose electrons to form a cation that then forms solids by ionic bonding. The octet rule predicts that the resulting cation will be stablest if its ...

Meaning, pronunciation, translations and examples WebOdd-electron molecules represent the first violation to the octet rule. Although they are few, some stable compounds have an odd number of electrons in their valence shells. With an odd number of electrons, at least one atom in the molecule will have to violate the octet rule. Examples of stable odd-electron molecules are NO, NO 2, and ClO 2. to ward against https://turbosolutionseurope.com

As shown in the above image of water molecule (H 2 O), each of the two hydrogen atoms (H) shares one electron with the oxygen atom. In other words, the hydrogen atom loses one electron to become stable.
