Take a look in ~ the picture below. Every of those colored balls is one electron. In one atom, the electron spin about the center, also called the nucleus. The electrons prefer to be in different shells/orbitals. Covering number one can only host 2 electrons, covering two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. Together you learn about elements with more than eighteen electron you will find that shell three have the right to hold an ext than eight. As soon as one covering is full, the following electron that is added has to relocate to the following shell.So... Because that the element of MAGNESIUM, you already know that the atomic number speak you the variety of electrons. That means there are 12 electrons in a magnesium atom. Looking at the picture, you have the right to see there space two electrons in shell one, eight in shell two, and also two an ext in covering three.

Magnesium OxideMagnesium (Mg) is able to bond through one oxygen (O) atom. The formula that the link is MgO. You deserve to see in the dot framework that the 2 atoms share four various electrons. Once a link is made with four electrons, the is referred to as a double bond. The is stronger than a solitary bond i m sorry only offers two electrons.

Magnesium DichlorideMagnesium dichloride is typically known as magnesium chloride. You can use either name once talking about the compound. Due to the fact that magnesium (Mg) has two extra electron it looks around for aspects which could use them. In this case, magnesium bonds through two chlorine (Cl) atom which each need one electron. Through the added electron, chlorine has a filled shell and also magnesium loses 2 electrons. Magnesium also has a fill shell!
