2019 A Level H2 Chemistry Paper 1 Question 8 - Deduce Germanium Properties from Period 3 Elements

This is a pretty straightforward question - 2019 A Level H2 Chemistry Paper 1 Question 8.

Given the properties for elements in Period 4 and Period 3 are similar, we are required to deduce the physical properties of germanium.

First we will have to determine which Group germanium is in.

From the Periodic Table we can find germanium under Group 14, which is in the same Group as carbon and silicon.

So we will expect germanium (Period 4) and silicon (Period 3) to have similar properties.

Looking at the options we will expect both germanium and silicon to have high melting points and act as semiconductors.

Therefore the answer to this question will be option B.
