2.1.1 1.1 Atoms Nucleus Protons Sub-atomic particle with + charge Neutrons Neutral charge sub-atomic particle Electrons Sub-atomic particle with - charge. Orbits the nucleus Element Substance can't be broken down chemically into simpler substances Atomic Number Number of Protons in an atom of an element Mass Number The number of neutrons plus the number of protons in nucleus SMALLEST COMPLETE UNIT OF ELEMENT. CONSISTS OF NUCLEUS AND ELECTRONS Isotopes ATOMS OF THE SAME ELEMENT WITH THE SAME ATOMIC NUMBER BUT WITH DIFFERENT NUMBER OF NEUTRONS GIVING THEM DIFFERENT MASS NUMBERS Physical Properties Properties which don't involve the chemical nature of the element or compound Chemical Properties Properties which affect the way in which an element or compound reacts with other substances some of isotopes's nuclei are unstable and undergo radioactive decay. Unstable Forces that make up the nucleus are unbalanced and there is an excess of internal energy. Be radioactive as unstable nucleus emits radiation to become stable
2.1.2 1.2 BONDING Ionic Bonding Chemical bond formed when atoms gain or lose electrons to form positive or negative ions Loss or gain in electrons give the ion a complete outer shell of electrons ION An atom which has lost or gained electrons to take a positive or negative charge. ionic bonds Strong force attraction between oppositely charged ions formed during ionic bonding. Electrostatic forces holding two oppositely charge ions together Covalent bonding Chemical bond formed when two or more atoms share electrons to gain a full, stable outer shell Covalent bonds Strong bonds which result from sharing electrons during covalent bonding Representing chemical reactiosn
