Take a look in ~ the picture below. Each of those colored balls is one electron. In an atom, the electrons spin about the center, also called the nucleus. The electrons favor to it is in in separate shells/orbitals. Shell number one have the right to only hold 2 electrons, shell two have the right to hold 8, and also for the first eighteen elements shell three have the right to hold a best of eight electrons. Together you learn about elements with much more than eighteen electron you will find that covering three can hold more than eight. As soon as one shell is full, the next electron that is included has to relocate to the following shell.So... For the aspect of MAGNESIUM, you already know that the atomic number tells you the number of electrons. That means there room 12 electron in a magnesium atom. Looking at the picture, you can see there room two electrons in shell one, eight in shell two, and also two much more in shell three.

Magnesium OxideMagnesium (Mg) is able come bond v one oxygen (O) atom. The formula of the compound is MgO. You have the right to see in the dot framework that the 2 atoms re-publishing four various electrons. Once a bond is make with 4 electrons, the is called a double bond. That is more powerful than a single bond which only supplies two electrons.

Magnesium DichlorideMagnesium dichloride is typically known as magnesium chloride. You have the right to use one of two people name once talking around the compound. Because magnesium (Mg) has actually two extra electrons it looks about for facets which can use them. In this case, magnesium bonds v two chlorine (Cl) atom which each need one electron. Through the additional electron, chlorine has actually a to fill shell and magnesium loses 2 electrons. Magnesium likewise has a fill shell!
