You will get to learn the difference between elements and compounds. Then discover the different types of bonds that hold atoms together and the differences between them.
After completing this tutorial, you will be able to complete the following:
To achieve stable electron sequence, how many electrons do two oxygen atoms share in their outer layers?
~ Because oxygen atoms must limit the number of electrons in their outer layers to eight, each oxygen atom has to share two of its outer layer electrons.
Why do nitrogen atoms need to share three electrons to achieve stable electron sequence?
~ Nitrogen atoms need to share three electrons to achieve stable electron sequence because they need a total of eight electrons in their outermost layers for stability but have only five naturally.
What is a covalent bond?
~ A covalent bond is the chemical bond formed by the sharingof electrons.
What is an oxygen molecule?
~ An oxygen molecule is a pair of oxygen atoms that is held together by a covalent bond.
