Front (Question)

How does ionisation energy change down group 2?

Back (Answer)

It decreases

Front (Question)

Why does ionisation energy decrease down Group 2?

Back (Answer)

The extra inner shells shield electrons Nucleus is further away from outer electrons due to more shells

Front (Question)

How does reactivity change down group 2?

Back (Answer)

Reactivity increases

Front (Question)

Why does reactivity increase down group 2?

Back (Answer)

It becomes easier for the outer electrons to be lost, as they have lower ionisation energies

Front (Question)

What do group 2 elements react with?

Back (Answer)

Water, oxygen and chlorine

Front (Question)

What are the group 2 elements?

Back (Answer)

Beryllium, Magnesium, Calcium, Strontium, Barium (Radium)

Front (Question)

What do group 2 elements produce when they react with water?

Back (Answer)

Hydroxides and hydrogen

Front (Question)

Which group 2 elements react with water?

Back (Answer)

All except Be, Mg reacts very slowly

Front (Question)

What do group 2 elements produce when they react with oxygen?

Back (Answer)

Oxides

#10

Front (Question)

What colour are group 2 oxides?

Back (Answer)

White

#11

Front (Question)

What do group 2 elements produce when they react with chlorine?

Back (Answer)

Chlorides

#12

Front (Question)

What colour are group 2 chlorides?

Back (Answer)

White

#13

Front (Question)

Oxides and hydroxides are…

Back (Answer)

…bases

#14

Front (Question)

What happens when group 2 oxides dissolve in water?

Back (Answer)

They form a strongly alkaline solution due to OH-

#15

Front (Question)

What happens when beryllium oxide is added to water?

Back (Answer)

It doesn’t dissolve, it is insoluble

#16

Front (Question)

What happens when magnesium oxide is added to water?

Back (Answer)

It reacts slowly and isn’t very soluble

#17

Front (Question)

When oxides and hydroxides are added to acid, what do they form?

Back (Answer)

They neutralise the acid to form salts

#18

Front (Question)

What is the equation for the reaction between MgO and H2O?

Back (Answer)

MgO + H2O —-> Mg(OH)2

#19

Front (Question)

What is the equation for the reaction between MgO and HCl?

Back (Answer)

MgO + 2HCl —-> MgCl2 + H2O

#20

Front (Question)

Solubility trends of group 2 depend on…

Back (Answer)

…the anion

#21

Front (Question)

If a group 2 compound has a singly charged anion (OH-) how does the solubility change down the group?

Back (Answer)

It increases

#22

Front (Question)

If a group 2 compound has a doubly charged anion (SO4 2-) how does the solubility change down the group?

Back (Answer)

It decreases

#23

Front (Question)

Which group 2 sulfate is insoluble?

Back (Answer)

Barium Sulfate

#24

Front (Question)

How does thermal stability change down group 1 and 2 carbonates and nitrates?

Back (Answer)

It increases
