What is the charge of a neutron
Neutral or no charge
100
What group number are the Noble Gases?
18
100
What happens that makes an atom turn into a negativly charged ion
Gains electrons
100
Do isotopes have the same number of protons?
Yes
100
Show which line is the y and x on a graph
X horizontal
y vertical
200
What is the mass number of an atom
Number of protons + Neutrons
200
What does the period tell us about an atom
Number of electron shells
200
Would Calcium which is in group 2 be more likely become a cation or anion
Cation (loses electrons)
200
Why does an isotope of an atom have a different mass?
different number of neutrons
200
Which axis should my INDEPENDENT variable be plotted?
X- Axis
300
How many protons and electrons does Aluminium have in a neutral atom?
13
300
Name 2 properties of an Akali metal
Silver
Very Reactive with water
Loses Electrons
Pairs with group 17
300
If an ion has a charge of +3, what does this mean?
It has lost 3 electrons
300
How would you show the isotope Carbon 14
6
C
14
300
Which of the following is NOT a rule when drawing graphs
- Start @ zero
- Use Pencil
- All axes labelled
- ALWAYS join the dots
- Use a ruler
Always join the dots
400
What is the total number of electrons if Mass is 25 and number of neutrons is 15
25-15 = 10 protons
proton = electron so 10
400
Describe one trend in atomic size as you move down a group.
Gets bigger
More Reactive
400
Why would sodium (group 1) readily react with chlorine (group 17)
Positive attracts negative
Sodium donates to chlorine
400
Would an isotope be considered stable? Why/Why not
No
There is too many neutrons which makes it weird
400
When data does not fit the line of best fit, what could this mean?
Error or outlier
500
Draw a representation of the Plum Pudding model
500
Why are noble gases unlikely to react with other elements?
They have full electron shells
500
An atom has the following
10 neutron
15 protons
17 electrons
Is it neutral or an ion, if so what charge
ion, -2
500
An atom has 26 protons and 30 neutrons.
a) Identify the element.
b) Write its isotope notation.
⁵⁶₂₆Fe
Iron

A student draws a graph with uneven intervals on the y-axis. Explain why this is problematic.
It distorts data representation and can mislead interpretation.
