Take a look in ~ the photo below. Every of those fancy balls is one electron. In one atom, the electrons spin about the center, additionally called the nucleus. The electrons choose to it is in in separate shells/orbitals. Shell number one have the right to only organize 2 electrons, covering two have the right to hold 8, and also for the an initial eighteen facets shell three have the right to hold a maximum of eight electrons. As you learn about elements with more than eighteen electrons you will discover that covering three can hold more than eight. When one covering is full, the following electron that is included has to relocate to the following shell.So... For the element of OXYGEN, you currently know the the atomic number tells you the number of electrons. That way there are 8 electrons in one oxygen atom. Looking at the picture, you have the right to see there space two electron in covering one and also six in shell two.

WaterThis is a water molecule. Even though girlfriend find facility names on various other molecules, everyone calls H2O "water". Water is made up of 2 hydrogen (H) atoms and one oxygen (O) atom. The formula because that water is H2O. The hydrogen atoms have filled orbitals with two electrons and also the oxygen atom is filled through eight electrons.

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

Hydrogen PeroxideTwo hydrogen (H) atoms can additionally bond v two oxygen (O) atoms, do the formula H2O2. That"s simply one much more oxygen 보다 water, but it is a completely different compound. You have the right to see that each of the Oxygen atoms has actually eight electrons, and the 2 Hydrogens have two electron each. See how the electrons room shared?
