Chapter 2: Chemistry of Life Campbell Text 7th Ed. PGS. 32 45 I. Matter A. Anything that takes up space and has mass to it. II. share A. The simplest form of a substance that cannot be broken by and still have the properties of that fixings. III. Compound A. Two or more(prenominal) elements bonded together resulting in NEW chemical properties to bulge light forth for the compound. B. This is an example of the Emergent Properties theme. (Fig. 2.2) An example: Water (H20) a motionless liquid and can sometimes be utilise to out a fire. Hydrogen by itself is a combustible hit man; Oxygen by itself is also a flammable gas. IV. CHNOPS (The roughly common elements in ALL manner forms.) and Trace elements (present in small amounts) (Table 2.1) V. Atom A. The smallest unit of payoff that has chemical properties because of it having all the subat omic separate. B. Atoms still maintain their legitimate properties of that element, because the subatomic parts argon all present. VI. Subatomic Particles (Small parts that make up atoms.)(sub mode below or frown)(Fig.2.4) A. Proton (These particles carry a commanding charge.) (They are rigid in the nucleus of an atom.) 1.

The crook of protons neer changes in an element. (This allowed the Periodic map to be created.) B. Neutron (These particles carry NO charge, which is called neutral.)(They are also set in the nucleus of an atom.) ! 1. The number of neutrons can change. (Atoms with different numbers of neutrons than the normal amount for that element are called Isotopes.) C. Electrons (These particles carry a negative charge.) (They are located in the Electron mist over. The cloud is created because electrons move at the speed of light which creates a blur around the atom.)(The electrons moving, which is called kinetic energy, is why they are associated with...If you requisite to get a honest essay, order it on our website: OrderCustomPaper.com
