Take a look in ~ the snapshot below. Each of those colored balls is one electron. In one atom, the electron spin around the center, likewise called the nucleus. The electrons favor to be in different shells/orbitals. Covering number one can only host 2 electrons, shell two deserve to hold 8, and also for the an initial eighteen facets shell three deserve to hold a best of eight electrons. As you learn about elements with an ext than eighteen electrons you will discover that shell three have the right to hold an ext than eight. When one covering is full, the following electron that is included has to move to the following shell.So... For the element of MAGNESIUM, you currently know the the atomic number speak you the variety of electrons. That method there are 12 electron in a magnesium atom. Looking in ~ the picture, you can see there room two electron in shell one, eight in covering two, and also two more in shell three.

Magnesium OxideMagnesium (Mg) is able come bond v one oxygen (O) atom. The formula of the link is MgO. You have the right to see in the dot framework that the two atoms re-superstructure four various electrons. As soon as a shortcut is do with four electrons, the is dubbed a double bond. That is stronger than a single bond i m sorry only uses two electrons.

Magnesium DichlorideMagnesium dichloride is generally known as magnesium chloride. You have the right to use one of two people name as soon as talking about the compound. Since magnesium (Mg) has actually two extra electron it looks about for facets which might use them. In this case, magnesium bonds v two chlorine (Cl) atoms which each require one electron. Through the added electron, chlorine has actually a filled shell and magnesium loses two electrons. Magnesium likewise has a filled shell!
