The two main types of chemical bonds are ionic and covalent bonds. Ionic bonds are formed when a transfer of electrons takes place from one atom to another, and covalent bonds are formed when electrons are shared between atoms. An atom becomes an ion when it gains or loses electrons.

Electrons and protons are both subatomic particles; however, they have different charges and locations within the atom.

Chapter 2: The Chemistry of Life

Electrons are negatively charged and found outside the nucleus, while protons are positively charged and found inside the nucleus. Electrons are also much smaller than protons. When atoms are joined together by covalent bonds, the structure that results is a molecule.

The property of radioactive isotopes that is useful for dating is that they break down at a constant rate over time. A catalyst lowers the activation energy. An enzyme is an example of a catalyst. A chemical reaction involves reactants changing to products.

Path A has the greatest activation energy. Graph I shows a reaction that absorbs energy. Pathway B is the pathway without enzyme, and Pathway C is the pathway with enzyme. The enzyme lowers the activation energy. This imaginary enzyme would work best when the body temperature is elevated.

All rights reserved.For example, all carbon atoms have 6 protons, but some have 6 nuetrons, some have 7 nuetrons, and a few have 8. For example, Chlorine Cl is a poisonous gas and Sodium Na is a metal, but when combined they form NaCl which is table salt. Oppositely charged ions Created by transferring the electrons attract each other and from an ionic bond. Shared Flashcard Set.
