What would a sample of the element bromine look like using such a diagram?


In this case we know bromine is a pure substance not a mixture. We also know that bromine is a liquid at 25 degrees Celsius. Finally we know that bromine is an element which is diatomic...that is it exists as a molecule which contains two atoms. We know ALL of this because;

1) you've memorize bromine is an element (one of those common elements);

2) you've memorized all the states of all the elements in the periodic table;

3) you've memorized the formula for every elemetn in the periodic table, and for bromine the formula is Br2.

Show me the diagram!
