- 1Atoma fundamental building block with a cluster of protons + neutrons inside the nucleus surrounded by a cloud of electrons
- 2ProtonA positively charged particle
- 3NeutronA particle which has no overall charge
- 4ElectronA negatively charged particle
- 5nucleusA cluster of protons + neutrons at the center of an atom
- 6Electron shellA layer that surrounds the nucleus
- 7electron configurationHow many electrons which are contained within each layer that surrounds the nucleus
- 8mass numberThe number of protons and neutrons in an atom
- 9atomic numberNumber of protons in the nucleus
- 10elementA substance made up of only one type of atom
- 11compoundMade up of 2 or more elements
- 12IsotopeWhen you have the same amount of protons in the nucleus but a different amount of neutrons
- 13Ionan atom that has lost electrons
- 14CationA positively charged ion
- 15AnionA negatively charged ion
- 16Ionic bondingA bond between a cation and an anion, their opposite charges causes a attraction towards each other
- 17ionic compoundA compound made up of cations and anions
- 18AcidReleases H+ ions into an aqeuous solution
- 19BaseReleases OH- ions
- 20AlkalineA base that dissolves in water
- 21pH scaleUsed to measure the acidity in a solution
- 22pH indicatorChanges colour to show you if a solution is acidic, neutral or basic
- 23Neutral pHnot an acid or base, an example of something that would appear neutral on the pH scale is water
- 24EndothermicAbsorbs energy
- 25ExothermicReleases energy
- 26CombustionReaction with oxygen, releases energy in the form of light and/or heat
- 27Complete combustionPlenty of oxygen, produces carbon dioxide and water vapour
- 28incomplete combustionLack of oxygen, produces carbon and carbon monoxide
- 29CorrosionBreak down of metals
- 30Aerobic respirationA reaction that uses oxygen to release energy stored in glucose
- 31PhotosynthesisEndothermic reaction - occurs in plants produces oxygen gas + glucose
- 32Reactants and productsReactants are always written on the left hand side and products are always written on the right hand side
- 33How do you work out the atomic mass?Protons + Neutrons
- 34How do you work out the neutronsAtomic mass - protons
- 35How to work out the electronsSame amount as the protons
- 36Atomic numberThe number the element is on the periodic table
- 37When an ion gains electrons the charge becomes?Negative
- 38When an ion loses electrons the charge becomes?Positive
- 39Which of the proton, neutron and electron is the smallest?Electron
- 40Which of the proton, neutron and electron is the heaviest?Proton
- 41Which of the proton, neutron and electron is positive?Proton
- 42Which of the proton, neutron and electron is negativeElectron
- 43Which of the proton, neutron and electron is neutral?Neutron
- 44Which of the proton, neutron and electron moves around the nucleusElectron
- 45Which of the proton, neutron and electron are in the nucleus?Protons and neutrons
- 46What can be said about the number of protons and electrons in an atom? Why?They are equal because there is an even amount of electrons and protons in an atom therefore making it balanced
- 47An atom has 8 protons, 8 electrons and 9 neutrons. What would it's atomic number and mass number be?The atomic number would be 8 and the mass 17
