PPT-Chapter 6 – Chemical Bonds

Jennie L Borders Standards SPS1 Students will investigate our current understanding of the atom b Compare and contrast ionic and covalent bonds in terms of electron movement SPS2 Students will explore the nature of matter its classification and its system for naming types of matter. (chapter 7). Bond markets. Bond. : . A long-term debt instrument in which a borrower agrees to make payments of principal and interest, on specific dates, to the holders of the bond. Primarily traded in the over-the-counter (OTC) market.. Bonds and Energy. Breaking chemical bonds . requires. energy. Forming chemical bonds . releases. energy. The amount of energy required or released for a chemical process depends on the number and types of bonds that are formed and broken.
