K and NO2
KNO2 and NO2
3.
What flame colour does a calcium salt give?
Brick red
Lilac
Pale green
Yellow
4.
Why does first ionisation energy decrease down Group 1?
Nuclear charge decreases
Outer electron is in a p orbital
Increased radius and shielding outweigh increased nuclear charge
Electrons pair up
5.

AgNO3
BaCl2
NaOH
Limewater
6.
Which carbonate decomposes most easily?
BaCO3
Na2CO3
K2CO3
MgCO3
7.
Which statement best describes Amphoteric?
A Group 1 element with one outer s electron.
A Group 2 element with two outer s electrons.
Able to react as both an acid and a base (not typical of Group 2 except Be).
A saturated solution of calcium hydroxide, which turns milky with CO2.
8.
Which statement best describes Shielding?
Breaking down a compound using heat.
A Group 2 element with two outer s electrons.
The reduction in nuclear attraction felt by outer electrons due to repulsion from inner electron shells.
The ability of a cation to distort the electron cloud of an anion; greater for small, highly charged ions.
9.
Which statement best describes Alkali metal?
The ability of a cation to distort the electron cloud of an anion; greater for small, highly charged ions.
A Group 1 element with one outer s electron.
A saturated solution of calcium hydroxide, which turns milky with CO2.
The reduction in nuclear attraction felt by outer electrons due to repulsion from inner electron shells.
10.
Which statement best describes Flame test?
Able to react as both an acid and a base (not typical of Group 2 except Be).
A Group 1 element with one outer s electron.
A test that identifies metal ions by the colour they give to a flame.
The reduction in nuclear attraction felt by outer electrons due to repulsion from inner electron shells.
