Topic 13 - Groups In The Periodic Table Flashcards
What is group 0 also known as?
The noble gases
What is the pattern of the reactivity in group 1?
The reactivity increase as you go down the group
What is a period?
A horizontal row in the periodic table
Where are the metals and non-metals located on the periodic table?
Metals are located on the left and non-metals are located on the right
How many electrons are in the outer shell of elements in group 1?
There is 1 electron
Which group do these elements belong to: helium, argon and neon
They belong to group 0
Which group of metals react violently with water?
Group 1 metals.
Which group are inert metals in?
Group 0.
Why is potassium more reactive than Sodium?
This because the electron is further away from the nucleus.
What products are formed when an alkali metal reacts with water?
Metal hydroxide + hydrogen gas
What are group 7 elements also called?
The Halogens
How many electrons do the halogens have on their outer shell?
7 electrons on their outer shell.
What colour flame is produced when potassium is added to water?
What is the word equation for this reaction?
-A Lilac/Purple coloured flame.
-Potassium+Water~>Hydrogen+Potassium Hydroxide.
Describe the trend in reactivity in group 7.
It gets less reactive as you go down the group.
State three properties of group 3 metals.
-Soft
-A low boiling point
-Easy to cut
What colour does the universal indicator solution turn when an alkali metal has reacted with water?
It turns Purple.
What is the most reactive element in group 7?
Fluorine.
What are the products that are formed in the displacement reaction: Chlorine+Potassium Bromide?
Potassium Chloride+Bromine.
Describe the trend in boiling points as you move down group 0.
It increases as you move down the group.
What does the reactivity pattern of group 1 mean?
The larger the atomic radius the easier it is to lose an outer electron.
