0 - 13Sodium has 11 electrons. What is it's structure?2, 8, 1
- 14Chlorine has 17 electrons. What is it's structure?2, 8, 7
- 15What are the properties of group 1 metals?They are more reactive as you go down the group.
They are good thermal and electrical conductors.
They react with water to produce an alkali and hydrogen.
They are soft compared with other metals. - 16What is shielding?When inner electrons block the outer electrons and the nucleus from attracting so easily.
- 17What types of atoms bond using covalent bonding?Non metals
- 18What types of atoms bond by ionic bonding?Metal and non metal atoms
- 19What is a molecule?Two or more atoms bonded together e.g. O2
- 20On the periodic table, what symbol is used for Sodium?Na
- 21What three particles make up an atom?Neutrons, protons, and electrons
- 22How many electrons are in the outer shell of the elements in Group 1 of the periodic table?1
- 23What do we call the chemical bond that forms due to the strong attraction between metal ions and non metal ions?ionic bond
- 24What is the main compound found in limestone?CaCO3
- 25What is thermal decomposition?Breaking down a compound when it is heated
- 26What is the word equation for the thermal decomposition of limestone?heat
Calcium carbonate -> calcium oxide +carbon dioxide - 27What is the general word equation for thermal decomposition?Metal carbonate -> metal oxide + carbon dioxide
- 28What is the word equation for adding a metal carbonate to an acid?Metal carbonate + acid ->carbon dioxide + water + metal salt
- 29What is the symbol for calcium hydroxide?Ca (OH)2
- 30What happens when you heat Calcium carbonate (limestone)?Thermal decomposition and it becomes calcium oxide (and carbon dioxide)
- 31What happens when you add water to calcium oxide?You get Calcium hydroxide (slaked lime)
- 32What happens when you dissolve calcium hydroxide in water and filter?You get Calcium hydroxide solution (limewater)
- 33What happens when you add carbon dioxide to calcium hydroxide solution (limewater)?You get calcium carbonate (limestone)
- 34What is another name for calcium oxide?Quicklime
- 35What are some uses of limestone?Statues, cement, buildings
- 36What is a precipitation reaction?When you add 2 solutions together to form a precipitate.
- 37What is a precipitate?An insoluble salt
- 38What is cement made from?Limestone and clay
- 39How do you make mortar?Mix sand and cement
- 40How do you make concrete?Sand, cement and aggregate (crushed rocks) mixed together.
- 41How many outer electrons does Helium have and why is this slightly unusual?2, all the other noble gases have 8
- 42What is calcium hydroxide?An alkali that neutralises acids
- 43Why is gold found in its native state?It is unreactive so it is not found as a metal ore
