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. constituent A. The simplest form of a substance that cannot be broken unconnected and still have the properties of that fixings. III. Compound A. Two or more elements bonded together resulting in NEW chemical properties to bulge bring 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 use 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 career forms.) and Trace elements (present in small amounts) (Table 2.1) V. Atom A. The smallest unit of reckon that has chemical properties because of it having all the subatom ic part. B. Atoms still maintain their headmaster properties of that element, because the subatomic parts argon all present. VI. Subatomic Particles (Small parts that make up atoms.)(sub mode below or trim down)(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 graph to be created.) B. Neutron (These particles carry NO charge, which is called neutral.)(They are also find in the nucleus of an atom.) ! 1. The number of neutrons can change. (Atoms with different metrical composition 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 slander. 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 wish to get a honest essay, order it on our website: OrderCustomPaper.com
