Name the animals...

The first-grade teacher was showing pictures of animals to her students to see how many they could name. She held up a picture of a lamb, and a little girl said, "That's a sheep!"

"That's right!" said the teacher. "How about THIS one?" she said, holding up a picture of the king of beasts.

"That's a lion!" answered a little boy.

"Right!" said the teacher. Then she held up a picture of a deer. No one volunteered an answer. She tried to help. "What does your mother call your father?"

Johnny said, "I know! That's a lazy old goat!"

Alfred Werner

Born 12 Dec 1866; died 15 Nov 1919 at age 52.Swiss chemist whose founding research into the structure of coordination compounds brought him the 1913 Nobel Prize for Chemistry. He demonstrated that stereochemistry was not just the property of carbon compounds, but was general to the whole of chemistry. His theory of chemical coordination (1893) recognized that many metals appeared to show variable valence and form complex compounds. Certain metals, such as cobalt and platinum, were capable through their secondary valences of joining to themselves a certain number of atoms or molecules. These were termed by Werner “coordination compounds.”and the maximum number of atoms (or “ligands”as he called them) that can be joined to the central metal is its coordination number.
