Chapter 8 Summary

In the last chapter, we learned about how ionic compounds connected with other molecules, and by doing this, there was a complete transfer or electrons. Each atom had its own electron, while in a covalent bond, there is a sharing of electrons which are held together. To make a covalent bond, electron sharing happens so that atoms get the electron configuration of noble gases. When a covalent bond forms and atoms get closer to each other, they attract. A single covalent bond is when two atoms are held together by a sharing a pair of electrons. Example H-H is equal to H:H the colon represents the shared pair of electrons since Hydrogen has only 1 electron, it forms a single covalent bond. A structural formula represents the covalent bonds by dashes - and shows the arrangement of covalently bonded atoms. Its basically the same thing as the colon, H:H or H-H. Covalent Bonds ONLY forms through Non Metals.You can draw electrons dot structures for molecules of compounds in much as the same way you draw diatomic elements. By taking the name of the element with the lowest number of electrons, and then surrounding it with the name of the element with the highest number of electrons.
