Definitions Chromosome: Structure in the nucleus of a cell, composed of DNA DNA: A double helix structure made of nucleotides Deoxyribose sugar: one of the three nucleotides of DNA Gene: a section of DNA that carries the code for a particular characteristic Nitrogenous base: part of a nucleotide, four types: ademine, thymine, guanine and cytocine Nucleotide: the building blocks of DNA, composed of a Deoxyribose sugar, Nitrogenous base and phosphate Phosphate: one of the components of a nucleotide Trait: a characteristic inherited by an organism Autosome: all chromosomes other than sex chromosomes Centromere: point where the two chromatids join together Chromatid: one of the strands of a chromosome following replication Diploid Number: number of chromosomes in the cell of an organism, represented as \(2N\).

Definitions Ion: An atom which is electrostatically charged Cation: Positively Charged ion Anion: Negatively Charged ion Valence shell: Outermost electron shell Octet: 8 electrons in the valence shell (2 if the element is Hydrogen or Helium) Catalyst: something that causes and/or speeds up chemical reactions Proton: positively charged hadron Neutron: neutral hadron Electron: negatively charged lepton exothermic: emits heat endothermic: absorbs heat Atomic number: number of protons Atomic mass: number of protons + number of neutrons Neutralisation: mixing an acid and a base to create water Corrosion: a gas or liquid chemically attacking an exposed surface Combustion: exothermic reaction between a fuel and oxidiser, which produces heat, light and gaseous products decomposition: when a single compound breaks down into two or more compounds oxidisation: corrosion reaction where the gas/liquid is Oxygen (O) Precipitation: formation of an insoluble solid when two soluble solutions are combined (product is known as a precipitate) Acid-Metal reaction: when an acid and metal react to produce a metallic salt and Hydrogen Periodic Table The periodic table is a table listing the fundamental building blocks of the universe: elements NOTE: ATOM and ELEMENT do NOT mean the same thing!
