Question 9 of 23

10. Suggest how the reactivity of fluorine compares to chlorine

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

Fluorine is less reactive than chlorine because it is more volatile

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

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

Question 10 of 23

11.

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

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

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

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

Neon is a noble gas

Question 11 of 23

12. Explain, by referring to the electronic configurations, why fluorine is more reactive than chlorine

Fluorine has the electronic configuration 2,7 and chlorine has 2,8,7. An extra outer electron is gained more easily by fluorine. This is because the outer shell is closer to the nucleus, so an extra electron is attracted more strongly. So fluorine is more reactive than chlorine

Fluorine has the electronic configuration 2,7 and chlorine has 2,8,7. An extra outer electron is gained more easily by chlorine. This is because the outer shell is closer to the nucleus, so an extra electron is attracted more strongly. So fluorine is more reactive than chlorine

Fluorine has the electronic configuration 2,8,7 and chlorine has 2,7. An extra outer electron is gained more easily by chlorine. This is because the outer shell is closer to the nucleus, so an extra electron is attracted more strongly. So fluorine is more reactive than chlorine

Fluorine has the electronic configuration 2,8,7 and chlorine has 2,7. An extra outer electron is gained more easily by fluorine. This is because the outer shell is closer to the nucleus, so an extra electron is attracted more strongly. So fluorine is more reactive than chlorine

13. If an element conducts electricity, is it typically a metal or a non-metal?

Depends on conditions

Metal

Non-metal

Either

Question 13 of 23

14.

If 2 similar test tubes contain acid, and a different metal sample is added to each, how might you tell which metal is more reactive?

The metal that disappears fastest is the less reactive metal

Fewer bubbles appear in the test tube with the more reactive metal

More bubbles will appear faster in the test tube with the more reactive metal

The test tube with the more reactive metal will turn cloudy faster

Question 14 of 23

15. What colour and state is iodine at room temperature?

red-brown liquid

dark grey solid

brown gas

yellow-brown liquid

Question 15 of 23

16. Explain, by referring to the electronic configurations, why lithium is less reactive than sodium.

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

Sodium has the electronic configuration 2,8,1 and lithium has 2,8,8,1. The outer electron in lithium is less attracted to the nucleus than in sodium because it is further away. So lithium is more reactive than sodium

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

Sodium has the electronic configuration 2,8,1 and lithium has 2,8,8,1. The outer electron in lithium is more attracted to the nucleus than in sodium because it is further away. So sodium is more reactive than lithium

Question 16 of 23

17. On the Periodic Table what is the meaning of the word Period? What does that tell us about the electron configuration of the atom?

same number of electron shells

Same electronic configuration

same number of electrons in the outer shell

Same number of electrons in the inner shell

Question 20 of 23

21. State the meaning of the term reducing agent

A substance that gives oxygen or removes electrons (it is itself reduced)

A substance that gives electrons or removes oxygen (it is itself reduced)

A substance that gives oxygen or removes electrons (it is itself oxidised)

A substance that takes oxygen or gives electrons (it is itself oxidised)

Question 21 of 23

22. 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.

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