Periodic Table
These metals are found in group 1 of the periodic table.
What are alkali metals?
This happens to group 1 reactivity as you go down the group.
What is increases?
This is the symbol for Calcium.
What is Ca?
This is the classification of oxygen gas.
Element, mixture or compound
What is an element?
This is the word equation for magnesium reacting with oxygen to form magnesium oxide.
What is magnesium + oxygen --> magnesium oxide.
This metal is found in group 1, period 3 of the periodic table.
What is sodium (Na)?
This happens to group 17 reactivity as you go down the group.
What is decreases?
This is the symbol for nitrogen.
What is N?
This is the classification of carbon dioxide (CO2)
Element, mixture or compound
What is a compound?

This type of substance contains only one type of atom.
This is the type of change when a new substance is formed.
What is chemical change?
This is how you can tell an element is a metal using the periodic table.
What is on the left hand side of the table?
Accept- left of the zig-zag line etc.
A student says “all elements in a group get more reactive as you go down.” This is only true for this group.
What is group 1?
