Metal Reactivity & Halogens quiz

1. 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.

Question 1 of 23

2.

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

Neon is a noble gas

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

3. 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 electrons in the inner shell

Same electronic configuration

same number of electron shells

same number of electrons in the outer shell

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 2,1. 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

Question 8 of 23

9. 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. 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.

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. Lithium would give off a orange flame, showing it is most reactive.
