Questions from Richard Harwood and Ian Lodge Solutions for Chapter: Elements and Compounds, Exercise 3: Exercise 3.3 with Hints & Solutions
Plot a graph of the melting and boiling point of the halogens against their proton numbers. Join the points for each property together to produce two separate lines on the graph.
Draw a line across the graph at (room temperature) to help you decide which elements are solid, liquid or gas at room temperature and pressure.

Which of the halogen are gases at room temperature and pressure?

Astatine is very rarely seen.What would your predict to be its physical state and colour at room temperature and pressure?

What is the trend observed in the melting point of the halogens as you go down the group?
