Sulfur

Charles I raised the royal standard in Nottingham on 22 August 1642, effectively marking the start of the First Civil War (1642-1646).

The conflict was the outcome of his long struggle with and eventual dismissal of Parliament, along with his imposition of taxes and attempts to impose religious uniformity.

Charles chose Nottingham because of its locality, as it was almost equidistant between London and the north.

He had great difficulty in persuading the people of Nottingham to his cause.

He was more than a little surprised when people didn't hand over their gunpowder and arms, or join his army.

Charles' problems in Nottingham should have been an omen for what was to come.

He lost the war and his head when he was executed on 30 January 1649 at Whitehall, London.

Sulfur is an essential element for life. It's found in amino acids(cysteine and methionine) and proteins.

Sulfur compounds are why onions make you cry, why garlic has a distinctive aroma, and why rotten eggs smell so horrible.

Although many sulfur compounds have a strong smell, the pure element is actually odourless.

Mankind has known about sulfur since ancient times. The element, also known as brimstone, primarily comes from volcanoes. While most chemical elements only occur in compounds, sulfur is one of relatively few elements that occurs in pure form.
