Question 3 of 23

4. 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 2,8,8,1. 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

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

5. 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 closer to the nucleus, so the attraction is weaker, 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 weaker, making it less reactive.

Question 8 of 23

9. How are elements arranged in the periodic table?

in order by mass number

in order by atomic number

in order by size

in no particular order

Question 9 of 23

10.

If pieces of lithium, potassium and sodium were cut and exposed to air, how could observations of the different reactions indicate the relative reactivity of those 3 metals?

Potassium would burn with a lilac flame showing it is most reactive. Lithium would not burn at all showing it is least reactive

Potassium would burn with a lilac flame showing it is least reactive. Lithium would not burn at all showing it is most reactive

Potassium would oxidise the most quickly, showing it is most reactive. Lithium would oxidise the slowest, showing it is least reactive.

Sodium would oxidise the most quickly, showing it is most reactive. Lithium would oxidise the slowest, showing it is least reactive.

Question 10 of 23

11. Explain how galvanising prevents rusting

Zinc is more reactive than iron. Zinc reacts with oxygen instead of iron

Zinc is more reactive than iron. Zinc reacts with water instead of iron

The zinc coating protects the iron, preventing it from exposure to oxygen and water

Zinc accepts excess electrons from the iron, preventing it from reacting

Metal

Either metal or non-metal

Question 14 of 23

15. On the Periodic table what is the meaning of the word Group? 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 15 of 23

16. Suggest how the reactivity of astatine compares to that of iodine. Explain your answer.

Astatine is less reactive because group 7 elements get less reactive with increasing atomic number.

Astatine is more reactive because group 7 elements get more reactive with increasing atomic number.

Astatine is more reactive because group 7 elements get less reactive with decreasing atomic number.

Astatine is more reactive because group 7 elements get more reactive with decreasing atomic number.

Question 16 of 23

17. 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 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 electrons in their outer shell

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

Question 22 of 23

23.

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

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

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

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