Back (Answer)

S (^2)

Front (Question)

What happens to all group 2 elements in redox reactions

Back (Answer)

Oxidised to form 2+ ions

Front (Question)

General symbol equation for Group 2 elements reacting with dilute acid

Back (Answer)

Front (Question)

General symbol equation for Group 2 elements reacting with water

Back (Answer)

Front (Question)

General symbol equation for Group 2 elements reacting with oxygen

Back (Answer)

Front (Question)

State and explain the reactivity of Group 2 elements

Back (Answer)

• Reactivity increases down group • More shells • More sheilding • Nuclur attraction decreases • Ionisation energy decreases • Less energy required to remove outer-shell electron

Front (Question)

Down Group 2, what happens to elements reducing power

Back (Answer)

Strong reducing agents

Front (Question)

State how solubility changes down the group and so the effect this has on the solution produced

Back (Answer)

• Solubility increases • More alkaline solutions form • Solutions have higher pH

Front (Question)

General symbol equation for metal oxide reacting with water

Back (Answer)

#10

Front (Question)

What property of group 2 compounds make them useful

Back (Answer)

They are basic

#11

Front (Question)

What is the use of calcium hydroxide in commerce, and what is the equation

Back (Answer)

• Neutralise soil acids in agriculture

#12

Front (Question)

What is the use of magnesium hydroxide and calcium carbonate in commerce, and what are their equations

Back (Answer)

• Antacids to treat indigestion

#13

Front (Question)

What electronic configurations do all group 7 elements end with

Back (Answer)

s(^2)p(^5)

#14

Front (Question)

What happens to all group 7 elements in redox reactions

Back (Answer)

Reduced to form 1- ions

#15

Front (Question)

How do all group 7 elements exist

Back (Answer)

Diatomic molecules

#16

Front (Question)

Why does the boiling point of group 7 elements decrease down the group

Back (Answer)

• London forces become stronger • More energy needed to break London forces

#17

Front (Question)

State and explain the trend in reactivity down the group 7

Back (Answer)

• Reactivity decreases • More shells • Atomic radius increases • More sheilding • Nuclear attraction decreases • Ionisation energy decreases • More energy required to attract outer-shell electron
