Take a look at the snapshot below. Each of those fancy balls is one electron. In one atom, the electron spin roughly the center, additionally called the nucleus. The electrons choose to it is in in separate shells/orbitals. Covering number one can only hold 2 electrons, covering two deserve to hold 8, and for the very first eighteen aspects shell three have the right to hold a preferably of eight electrons. As you learn around elements with more than eighteen electron you will find that covering three can hold much more than eight. As soon as one covering is full, the next electron that is included has to move to the next shell.So... For the aspect of OXYGEN, you currently know the the atomic number speak you the number of electrons. That means there room 8 electrons in an oxygen atom. Looking in ~ the picture, you have the right to see there room two electrons in covering one and six in covering two.

WaterThis is a water molecule. Also though you find complex names on other molecules, everyone calls H2O \"water\". Water is comprised of two hydrogen (H) atoms and one oxygen (O) atom. The formula for water is H2O. The hydrogen atoms have filled orbitals v two electrons and the oxygen atom is filled with eight electrons.

Lithium OxideTwo lithium (Li) atoms have the right to bond through one oxygen (O) atom, make the formula Li2O. Oxygen likes to have two additional electrons to do it happy. Each lithium atom offers one. You have the right to see that the Oxygen atom has eight electron (6 the its own, and also one from each lithium), and also the 2 lithium atoms have two electrons each.

Hydrogen PeroxideTwo hydrogen (H) atoms can likewise bond through two oxygen (O) atoms, make the formula H2O2. That\"s simply one much more oxygen than water, but it is a completely different compound. You can see the each of the Oxygen atoms has eight electrons, and the two Hydrogens have actually two electrons each. See exactly how the electrons room shared?
