Unit 1 - Part 1

What are all elements made up of? Atoms
What is the centre of an atom called? Nucleus
What are the three sub-atomic particles called? Protons, Electrons, Neutrons
What are the two sub-atomic particles in the nucleus? Protons, Neutrons
Where are the electrons found? Circling the nucleus on energy levels.
Why are atoms neutral? The number of protons equals the number of electrons.
What is the atomic number? It equals to the number of protons in the atom.
What is the atomic mass? It equals to the number of protons + number of neutrons
How are electrons arranged? In energy levels round the nucleus.
How many electrons can the first energy level hold? 2
How many electrons can the second energy level hold? 8
What is Isotopes? Atoms of the same element but with a different number of neutrons.
Explain Covalent Bonding It is the sharing of electrons to make two atoms stable.
What are the 7 diatomic molecules? Hydrogen, Oxygen, Nitrogen, Fluorine, Chlorine, Bromine, Iodine
What diatomic molecules have a single bond? Hydrogen, Fluorine, Chlorine, Bromine, Iodine
What diatomic molecules have a double bond? Oxygen
What diatomic molecules have a triple bond? Nitrogen
What is a molecule? It is two or more atoms held together by covalent bonds.
Do metals form covalent bonds? No, only non-metals form covalent bonds.
What are the valencies of Groups 1,2,3,4,5,6 and 7? Group 1= 1 Group 2= 2 Group 3= 3 Group 4= 4 Group 5= 3 Group 6= 2 Group 7= 1
What is the prefix of 1 atom? mon-
What is the prefix of 2 atoms? di-
What is the prefix of 3 atoms? tri-
What is the prefix of 4 atoms? tetra-
What is the prefix of 5 atoms? penta-
What is the prefix of 6 atoms? hexa-
What is the prefix of 7 atoms? hepta
What is the prefix of 8 atoms? octa
What is the prefix of 9 atoms? nona
What is the prefix of 10 atoms? deca
Explain Conductor A material that allows the flow of electricity.
Explain non-conductor (or insulator) A material that does not allow the flow of electricity.
Explain Metallic Bonding Strong attraction between closely packed positive metal ions and a 'sea' of delocalised electrons. The attraction between the metal ions and the delocalised electrons must be overcome to melt or to boil a metal.
For an electric current to flow, what are the two things needed? -Charged Particles -The charged particles must be able to move
Explain Ionic Bonding It is when non-metals steal electrons from metals. Non-metals gain electrons Metals lose electrons
What are the charged particles in an ionic compound called? Ions
What is Electrolysis? It is the breaking up of a compound using electricity.
What is Electrolyte? A liquid that conducts electricity by the movement of ions.
What are covalent networks? A few covalent compounds such as silicon dioxide that have very high melting points.
