1. Atomic Structure & Chemical Bonding. Goal. To understand why atoms form molecules. Objectives. After this chapter, you should be able to. interpret the properties of elements that are important for life from the periodic table. understand why and how atoms form bonds. draw Lewis dot and line structures to represent chemical bonds. What is life?
Definition: What is a Chemical Bond? Chemical bonds are forces that hold the atoms together in a molecule. They are a result of strong intramolecular interactions among the atoms of a molecule. The valence (outermost) electrons of the atoms participate in chemical bonds. When two atoms approach each other, these outer electrons start to interact.
Chapter 10: Chemical Bonding. Chemical Bonds are the attractive forces that hold atoms together in more complex units. An understanding of how and why atoms attach together in the manner they do is central to chemistry. Lewis Theory. Emphasizes the importance of valence electrons.
2 ημέρες πριν · A chemical bond is an interaction that holds molecules and compounds together by the sharing or exchanging of electrons. When an atom comes into proximity to another atom and its valence (outer) electrons are attracted to the positive (nuclear) charge of the other atom, a bond between the two atoms can be formed.
It describes the living cell, its organelles and the general foundations determining cell structure and functions. It also covers relevant chemical concepts, properties of water as main constituent of life, chemicals elements and their distribution in earth and cell, different chemical bonds, functional groups chemical equilibrium and ...
