Metal Reactivity & Halogens quiz

1.

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

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

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

7. 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 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.

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

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

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

Question 14 of 23

15. 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?

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

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

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.

oxygen and water

Question 16 of 23

17. 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 2,8,8,1. 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 2,8,8,1. 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

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 2,1. 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

Question 18 of 23

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

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 different numbers of electrons in their outer shell

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

22. Which is more reactive: lithium or rubidium?

Depends on the temperature

Lithium

Rubidium

Depends on the pressure

Question 22 of 23

23. Why does chlorine react with hydrogen bromide?

Chlorine is more reactive and so displaces the bromine.

Bromine is more reactive so it is displaced

Chlorine is more reactive as so displaces the hydrogen

Hydrogen is more reactive and displaces the bromine
