For Mg to acquire the same electron configuration as Neon, it must lose 2 of its valence electrons. It thus obtains a 2+ charge. The 2 electrons that it loses can go to an accepting atom, such as O, S, Cl, etc. to form an ionic bond, where the accepting atom has a negative charge.
It accepts one electron.
sulfur
Alkali metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.
Every halogen has the capacity to accept one electron from a sodium atom and to thereby achieve a noble gas electron configuration of eight valance electrons. The halogens are fluorine, chlorine, bromine, iodine, and astatine.
Magnesium bicarbonate forms magnesium hydroxide on boiling because of the high temperatures.
study island answer- It gives up two electrons
It accepts one electron.
It accepts one electron.
It accepts one electron.
Argon
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
This is an oxidation reaction; magnesium burn in oxygen.
When magnesium is heated in air, it forms magnesium oxide and so the total mass increases.
A fluorine atom gains one atom in order to achieve the same electron configuration as neon. In doing so, the fluorine atom forms a fluoride ion with a 1- charge with the formula F-. As a negatively charged ion, it can form ionic bonds with various positively charged ions.
Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.
sulfur
Alkali metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.
