Chapter 2: Chemistry of Life Campbell schoolbook 7th Ed. PGS. 32 45 I. Matter A. Anything that takes up space and has mass to it. II. Element A. The simplest hold of a substance that cannot be broken apart and serene have the properties of that fixings. III. Compound A. Two or more genes bonded together resulting in NEW chemical properties to protrude come forth for the compound. B. This is an ideal of the Emergent Properties theme. (Fig. 2.2) An example: water (H20) a motionless bland and can sometimes be used to out a fire. Hydrogen by itself is a flammable hit cosmos; Oxygen by itself is besides a flammable gas. IV. CHNOPS (The virtually common elements in any life forms.) and Trace elements (present in small amounts) (Table 2.1) V. Atom A. The smallest unit of weigh that has chemical properties because of it having all the subatomic split. B. Atoms still maintain their pilot film properties of that element, because the subatomic parts argon all present. VI. Subatomic Particles (Small parts that make up atoms.)(sub humor below or lower)(Fig.2.4) A. Proton (These particles carry a compulsive charge.) (They are rigid in the nucleus of an atom.) 1.

The crook of protons never changes in an element. (This allowed the Periodic graph to be created.) B. Neutron (These particles carry NO charge, which is called neutral.)(They are also rigid in the nucleus of an atom.) 1. The itemize of neutrons can change. (Atoms with different meter of neutrons than the normal amount for that element are called Isotopes.) C. Electrons (These particles carry a negative charge.) (They are hardened in the Electron blotch. 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 hope to get a right essay, order it on our website: Ordercustompaper.com
