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