Reactivity
Name the table used to determine the relative reactivity of metals.
Reactivity Series.
Where are metals found in the periodic table?
The left hand side.
Dmitri Mendeleev
Complete the equation:
Acid + Metal -->
Salt + Hydrogen
Define Element.
Made up of lots of the same type of atom
Describe the trend in reactivity of Group 1 elements.
Elements become more reactive as you move down the group.
What was Mendeleev able to do that set him apart from other chemists at the time.
Predict undiscovered elements and leave gaps in the periodic table.
Groups are the vertical columns and tell us how many electrons are in the outer shell.
Complete the equation:
Acid + Metal Carbonate -->
Salt + Carbon Dioxide + Water
Define compound and Mixture
Compound: Two or more elements chemical bonded in a fixed ratio
Mixture: Two or more elements mixed together but not chemically bonded.
Describe the trend in reactivity of Group 7 elements.
Elements become less reactive as you move down the group.
Name the salt produced by Hydrochloric Acid.
Chloride
Outline periods and what they tell us.
They are the horizontal rows and tell us how many electron shells an element has.
Complete the following reaction.
Iron + Hydrochloric acid -->
Iron Chloride + Hydrogen
Define Displacement Reactions.
When a more reactive element takes the place of a less reactive element.
They are inert (unreactive) because they have a full outer shell.
Shiny, Malleable, Ductile, Good Conductors, High Melting Point.
Recall the name of Group 1, 7, and 0 elements.
Group 1 - Alkali Metals, Group 7 - Halogens, Group 0 - Noble Gases.
Complete the following reaction.
Aluminium Carbonate + Nitric Acid -->
Aluminium Nitrate + Carbon Dioxide + Water
Define Inert.
An element that does not react, a full outer shell.
State 2 properties of Group 1 metals:
Highly reactive, Soft, Low density, Low melting point
Write the chemical formula for Hydrochloric Acid.
HCl
Outline a difference between the first periodic table and the modern periodic table and how elements are arranged.
The first periodic table was arranged by atomic mass, and the modern periodic table is arranged by atomic number.
Complete both of the following reactions:
1. Lead Oxide + Phosphoric Acid -->
2. Copper Sulphate + Magnesium -->
1. Lead Phosphate + Water
2. Magnesium Sulphate + Copper
Define a thermite reaction.
Reaction between metals that releases a lot of heat and molten metal.
