Periodicity

?
Where are metals in the periodic table?
Block S and D
1 of 16
Where are non-metals in the periodic table?
Block P
2 of 16
What are elements which fall on the line between metal and non-metal called?
Metalloids
3 of 16
In which direction do metals get more reactive on the table?
Going down
4 of 16
In which direction do non-metals get more reactive on the table?
Going up
5 of 16
In period 3, which elements are metals?
Sodium, magnesium and aluminium
6 of 16
In period 3, which element is a giant covalent semi metal?
Silicon
7 of 16
In period 3, which elements are molecular non-metals?
Phosphorus, sulfur and chlorine
8 of 16
In period 3, which is a noble gas?
Argon
9 of 16
Which molecular structure in period 3 has the highest boiling point, why?
Silicon, S8 - more van de waals due to 8 atoms creating the one molecule
10 of 16
Why do boiling points going across the metals?
More delocalised electrons and higher charge
11 of 16
What is the trend in atomic radii across period 3?
Radii decrease due to more protons increasing the charge creating a stronger pull on outer electrons
12 of 16
What is the trend in ionisation energies across period 3?
Ionisation energies increase due to protons increasing but electrons staying in the same shell - making it harder to lose one electron
13 of 16
What occurs between group 2 and 3 in relation to ionisation energies?
Drop due to group 3's electrons are in a higher energy P sub shell so less energy is require to remove one electron. Group 2 is in a S-subshell
14 of 16
What occurs between group 5 and 6 in relation to ionisation energies?
Group 6 electron is easier to remove as it experiences electron repulsion therefore requires less energy
15 of 16
What part in successive ionisation energies tells us which group the element is in?
The first big jump
