Take a look at the snapshot below. Each of those fancy balls is an electron. In an atom, the electron spin about the center, additionally called the nucleus. The electrons favor to it is in in separate shells/orbitals. Covering number one have the right to only organize 2 electrons, covering two deserve to hold 8, and also for the an initial eighteen facets shell three can hold a preferably of eight electrons. As you learn about elements with much more than eighteen electron you will discover that shell three can hold an ext than eight. As soon as one shell is full, the next electron that is added has to relocate 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 space 12 electrons in a magnesium atom. Looking at the picture, you have the right to see there are two electron in shell one, eight in shell two, and two more in covering three.

Magnesium OxideMagnesium (Mg) is able to bond with one oxygen (O) atom. The formula the the link is MgO. You deserve to see in the dot framework that the two atoms re-publishing four various electrons. Once a link is make with four electrons, it is referred to as a double bond. That is more powerful than a single bond i m sorry only uses two electrons.

Magnesium DichlorideMagnesium dichloride is frequently known as magnesium chloride. You have the right to use either name once talking about the compound. Because magnesium (Mg) has two extra electrons it looks approximately for elements which could use them. In this case, magnesium bonds with two chlorine (Cl) atoms which each require one electron. With the extr electron, chlorine has a filled shell and magnesium loses 2 electrons. Magnesium additionally has a to fill shell!
