Front (Question)

What are the group 1 elements also known as?

Back (Answer)

Alkali metals

Front (Question)

What is the general trend in density down group 1?

Back (Answer)

Increasing

Front (Question)

What is the general trend in melting point down group 1?

Back (Answer)

Decreasing

Front (Question)

What is the general trend in reactivity down group 1?

Back (Answer)

Increasing

Front (Question)

Explain the trend in reactivity down group 1.

Back (Answer)

Reactivity increases as you go down the group; because the outer shell electron gets further from the nucleus; so there is a weaker force of attraction between the outer shell electron and the nucleus; so the outer shell electron is lost more readily

Front (Question)

Which group 1 element reacting with water does this best describe? Fizzes steadily and slowly dissapears

Back (Answer)

lithium

Front (Question)

Which group 1 element reacting with water does this best describe? melts to form a silver ball, fizzes vigourously and quickly disappears

Back (Answer)

sodium

Front (Question)

Which group 1 element reacting with water does this best describe? immediately ignites, burns with a lilac flame and very quickly disappears

Back (Answer)

potassium

Front (Question)

What two products are formed when group 1 metals react with water?

Back (Answer)

hydrogen and a metal hydroxide

#10

Front (Question)

Would you expect the solution formed from the reaction of a group 1 metal with water to be acidic or alkaline?

Back (Answer)

alkaline due to the formation of a metal hydroxide

#11

Front (Question)

What name are the group 17 (old group 7) elements known by?

Back (Answer)

The halogens

#12

Front (Question)

What name is given to a compound containing a group 17 (old group 7) element?

Back (Answer)

Halide

#13

Front (Question)

What is the general trend in reactivity of the halogens going down the group?

Back (Answer)

Decreasing

#14

Front (Question)

What is the general trend in melting and boiling points of the halogens going down the group?

Back (Answer)

Increasing

#15

Front (Question)

What is the general trend of the colours of the halogens going down the group?

Back (Answer)

Tend to get darker

#16

Front (Question)

What is the general trend in the density of the halogens going down the group?

Back (Answer)

Increasing

#17

Front (Question)

Explain the trend in reactivity of the halogens going down the group.

Back (Answer)

Reactivity decreases as you go down the group; because the outer shell gets further from the nucleus; so there is a weaker force of attraction between the outer shell electrons and the nucleus; so electrons are gained less readily

#18

Front (Question)

Which halogens can displace other halogens from their halide compounds?

Back (Answer)

More reactive halogens can displace less reactive halogens from their halide compounds

#19

Front (Question)

Which halogens can displace iodine from NaI?

Back (Answer)

fluorine, chlorine and bromine

#20

Front (Question)

Which halogens can displace bromine from KBr

Back (Answer)

fluorine and chlorine

#21

Front (Question)

Which halogens can displace chlorine from KCl

Back (Answer)

fluorine

#22

Front (Question)

What are the products of this displacement reaction? Cl2 + 2KBr –>

Back (Answer)

Cl2 + 2KBr –> 2KCl + Br2

#23

Front (Question)

What are the products of this displacement reaction? F2 + 2NaI –>

Back (Answer)

F2 + 2NaI –> 2NaF + I2

#24

Front (Question)

What observations would you expect to make when adding aqueous chlorine solution to a solution of potassium bromide?

Back (Answer)

Colourless potassium bromide solution turns orange/brown due to the formation of bromine
