With chemical symbols on the periodic table 2 of 25 What is at the basic structure of an atom A tiny central nucleus with electrons around it 3 of 25 What are the columns called? Groups 4 of 25 What doe the group number represent? Number of atoms in outer shell 5 of 25 What is the charge of a proton? positive 6 of 25 What is the charge of a neutron? No charge, 0 7 of 25 What is the charge of an electron? negative 8 of 25 What is the overall charge of an atom and why? neutral because there are the same number of protons as electrons 9 of 25 What is the atomic number of an atom? The number of protons 10 of 25 What is the mass number of an atom? The number of protons and neutrons 11 of 25 How are atoms arranged in the periodic table? In order of their atomic number 12 of 25 Which shell has the lowest energy level? The first 13 of 25 What are group one metals called? The reactivity series 14 of 25 Why are the group one metals so reactive? They only have one electron in their outer shell so need lots more 15 of 25 What are group 0 metals called? The noble gases 16 of 25 Why are the noble gases unreactive? They have a full outer shell 17 of 25 How do metals and non-metals bond? by transferring electrons 18 of 25 how do non-metals and non-metals bond? by sharing electrons 19 of 25 What are the bonds between metals and non-metals called? Ionic bonds 20 of 25 What are the bonds between non-metals and non-metals called? Covalent bonds 21 of 25 In ionic bonding, does the metal give away or receive the electron it gives it away 22 of 25 Why do ions form bonds? The positive metal atom attracts the negative non-metal atom 23 of 25 What happens to the atoms in a chemical reaction? No atoms are created or destroyed in a chemical reaction 24 of 25 How does the mass of reactants compare with the mass of products in a chemical reaction? They are equal 25 of 25
