Take a look at the snapshot below. Each of those fancy balls is one electron. In an atom, the electrons spin approximately the center, additionally called the nucleus. The electrons like to be in separate shells/orbitals. Shell number one have the right to only organize 2 electrons, covering two have the right to hold 8, and for the an initial eighteen elements shell three have the right to hold a preferably of eight electrons. Together you learn around elements with much more than eighteen electrons you will uncover that shell three deserve to hold an ext than eight. As soon as one covering is full, the next electron the is added has to move to the next shell.So... For the aspect of LITHIUM, you currently know that the atomic number speak you the number of electrons. That means there are 3 electron in a lithium atom. Looking at the picture, you can see there space two electrons in covering one and also only one in covering two.

Lithium OxideTwo lithium (Li) atoms have the right to bond with one oxygen (O) atom, make the formula Li2O. Oxygen likes to have actually two extr electrons to make it happy. Every lithium atom gives one. You can see that the oxygen atom has actually eight electrons (6 of its own, and one from every lithium), and also the 2 lithium atoms have two electrons each.

Lithium FluorideOne lithium atom can incorporate with one fluorine (F) atom. Together, they do the formula LiF. Fluorine has actually seven electrons of it"s own. Lithium gives up that one electron to do both atom happy. So the fluorine atom has actually eight electrons, and also a filled external shell.
