Question 4 of 23

5. If pieces of lithium, potassium and sodium were added to water, how could observations of the different reactions indicate the relative reactivity of those 3 metals?

Sodium would bubble the least vigorously, showing it is least reactive. Lithium would give off a orange flame, showing it is most reactive.

Sodium would bubble the least vigorously, showing it is least reactive. Potassium would give off a orange flame, showing it is most reactive.

Lithium would bubble the most vigorously, showing it is most reactive. Potassium would give off a lilac flame, showing it is least reactive.

6.

Explain, in terms of the arrangement of electrons in its atoms, why neon is very unreactive

Neon has an even number of electrons so it does not need to form bonds

Neon has the same number of electrons and protons so it is unreactive

Neon is a noble gas

Neon has 8 electrons in the outer shell, so it is full. Therefore it does not easily gain or lose electrons

Question 6 of 23

7. Complete the equation for the reaction by inserting the state symbols: 2Li(....) + 2H₂O(....) → 2LiOH(...) + H₂(....)

2Li(s) + 2H₂O(aq) → 2LiOH(s) + H₂(g)

2Li(s) + 2H₂O(l) → 2LiOH(s) + H₂(aq)

2Li(s) + 2H₂O(aq) → 2LiOH(aq) + H₂(g)

2Li(s) + 2H₂O(l) → 2LiOH(aq) + H₂(g)

Question 7 of 23

8. Describe how the reaction of hydrochloric acid and various metals could be used to determine the relative reactivity of those metals

Add the various metals to different test tubes containing the same volume and concentration of acid. The metals which bubble more are less reactive.

Add the various metals to different test tubes containing the same volume and concentration of acid. The metals which bubble more are more reactive.

Add the various metals to different test tubes containing the same volume but different concentrations of acid. The metals which bubble more are less reactive.

Add the various metals to different test tubes containing the same volume but different concentrations of acid. The metals which bubble more are more reactive.

10. Why do elements in the same group of the periodic table have similar chemical properties?

Elements in the same group of the periodic table have the same number of electrons in their outer shell

Elements in the same group of the periodic table have different numbers of electrons in their outer shell

Elements in the same group of the periodic table are all the same type of element (metal, non-metal etc.)

Elements in the same group of the periodic table have the same number of protons

Question 10 of 23

11. An experiment investigates which of metals X and Z is more reactive. The result is X + ZSO₄ → XSO₄ + Z. Which metal is more reactive?

X

ZSO₄

XSO₄

Z

Question 11 of 23

12. Suggest how the reactivity of fluorine compares to chlorine

Fluorine is more reactive than chlorine because it has a lower boiling point

Fluorine is less reactive than chlorine because it is more volatile

Fluorine is more reactive than chlorine as it is higher in the group.

Fluorine is less reactive than chlorine as it is more stable as an element

Question 12 of 23

13. Explain why bromine is less reactive than chlorine

Both chlorine and bromine react by their nucleus attracting an electron to fill their outer shell. The outer shell of bromine is closer to the nucleus, so the attraction is stronger, making it less reactive.

Both chlorine and bromine react by their nucleus attracting an electron to fill their outer shell. The outer shell of bromine is further from the nucleus, so the attraction is stronger, making it less reactive.

14. If a substance loses oxygen in a reaction how is the process described?

Hydrolysis

Oxidation

Combustion

Reduction

Question 14 of 23

15. Explain, by referring to the electronic configurations, why potassium is more reactive than sodium.

Sodium has the electronic configuration 2,8,1 and potassium has 2,1. The outer electron lost from potassium is closer to the nucleus therefore the electron is more attracted by the nucleus. So potassium is more reactive than sodium

Sodium has the electronic configuration 2,8,1 and potassium has 2,1. The outer electron lost from potassium is further from the nucleus therefore the electron is less attracted by the nucleus. So potassium is more reactive than sodium

Sodium has the electronic configuration 2,8,1 and potassium has 2,8,8,1. The outer electron lost from potassium is further from the nucleus therefore the electron is less attracted by the nucleus. So potassium is more reactive than sodium

Sodium has the electronic configuration 2,8,1 and potassium has 2,8,8,1. The outer electron lost from potassium is closer to the nucleus therefore the electron is more attracted by the nucleus. So potassium is more reactive than sodium
