Why do some elements symbols not match their name example iron Fe?

For example Fe is irons symbol. Fe is ferrum, iron in Latin. Potassium is a alkali metal. This means that its radioactive.

Why do some elements have 2 letters?

Hydrogen and Oxygen are two of the most commonly used elements but are also very highly recognized by most people, hence an H and an O are used for the symbols. … So some single letters were used for some highly recognized elements but it was necessary to use two letters to differentiate between most of the elements.

Why is element 118 so expensive?

The most expensive natural element is francium, but it decays so quickly it can’t be collected to be sold. If you could buy it, you’d pay billions of dollars for 100 grams. The most expensive natural element that is stable enough to purchase is lutetium. … Atoms of synthetic elements cost millions of dollars to produce.

Technetium. The first element that was synthesised, rather than being discovered in nature, was technetium in 1937. This discovery filled a gap in the periodic table, and the fact that no stable isotopes of technetium exist explains its natural absence on Earth (and the gap).

PalladiumPalladium is the most expensive of the four major precious metals – gold, silver and platinum being the others. It is rarer than platinum, and is used in larger quantities for catalytic converters.
