Interesting and Weird Metallic Elements
I really like science. There are so many interesting and weird things to know about.
This page is about metallic elements.
Did you know?
• The word ‘metal’ comes from the Greek word metallon which means to mine or to dig out of the ground.
• Three-quarters of all the elements are metals.
• Lithium is so light, it will float on water. (But not for long. Water reacts violently with lithium!)
• If you put all the gold in the whole world into one cube it would only be 60′ x 60′ x 60′ (at least that what some scientists think).
• Mercury is liquid at room temperature. So are cesium and gallium (if your room is heated to 85˚F).
• Technetium is so rare it wasn’t even discovered until 1936. And it is totally radioactive.
• Some people are allergic to nickel.
• Iron is what makes your blood red. Crabs and other crustaceans do not have iron in their blood. They have copper, which makes their blood blueish. Some sea shrimps have green blood because they use vanadium to transport oxygen.
• The most common metal found in the Earth’s crust is aluminum, but before an easy method was found to isolate it from its ore, aluminum was more expensive than gold. In England, aluminum is spelled with an extra i: aluminium and pronounced al-you-MIN-ee-um.
• The center of the Earth is molten iron.
• In my opinion, the metallic elements with the weirdest names are: praseodymium (prays-ee-oh-DIM-ee-um) and dysprosium (dis-PROS-ee-um).
• If you drop a piece of potassium into water, it will explode!
• Sodium is so soft, you can cut it with a knife.
• All metallic elements are silver, gray, or almost black…except two: gold and copper.
