THE PERIODIC TABLE OF THE ELEMENTS: AN EASY GUIDE FOR HARD AND UNKNOWN ELEMENTS

This is a guide to the Periodic Table of the Elements, especially made for the ones that are not known to people. In this infogram, we will look at 6 different kinds of elements and see its history, how it's used for, and more! So if you're curious, continue on the slide!

It was discovered by the Swiss chemist Jean Charles Galissard de Marignac, who separated an independent component from rare earth called yttria. He called it ytterbia, because of the name of the village near him when he found the component. Currently, it is now called Ytterbium.

Ytterbium

Ytterbium is a chemical element with the symbol Yb and atomic number 70.

It is an silvery grey colored metal. It is exceptionally rare together with lutetium.

It was discovered by the Finnish chemist Johan Gadolin. He identified the sample in 1789, and completed his work in 1794. (A man called Karl Axel Arrhenius sent him the sample of the new rock.) He thought it was one element that was been oxided, and thought he found a new element called Yttrium, but it wasn't. --> Click the photo for more.

Yttrium

Yttrium is a chemical element with the symbol Y and atomic number 39. It is the first element that got separated from rare earth.

IIt is an silvery grey colored metal. P.S. Don't get confused with Ytterbium!

It was discovered by the German ALchemist Hennig Brand. Brand experimented with human urine, which contains quite a lot of dissolved phosphates. He was actually trying to make the philosopher's stone through the distillation of some salts by evaporating urine, and in the process he found a white material that glowed in the dark and burned well. It was named phosphorus from then.

Phosphorus

Phosphorus is a chemical element with the symbol P and atomic number 15. The word 'phosphorus' means phos which is in Greek, light + phorus which is also in Greek: carrier.

There are many allotropes of phosphorus, so if you're curious, click on the photo!

Potassium

Potassium was first isolated by the British chemist Humphry Davy in 1807. He isolated it from electrolysis of potash(KOH).

Potassium is a chemical element with the symbol K and atomic number 19. Potassium means ash of vegetation (English - Potash), and another name Kalium means ash of plants. (in Arabian)

It is a silvery white metal which is in the alkali family. (examples of alkali metals, which is where potassium belong , are sodium, lithium, rubidium, Cesium, and francium.

Niobium

Niobium was first discovered in an ore sample from Connecticut by the English chemist Charles Hatchett.

Niobium is a chemical element with the symbol Nb and atomic number 41. Niobium is very similar with Tantalum, so the name of it is from the daughter of King Tantalos from the Greek myth, Niobe.

IIt is an silvery-grey metal.P.S. Don't get confused with Tantalum! (Though it has been.)

It was discovered by physicist Emilio Gino Segre and other scholars in 1937. They used particle accelerator to collide Molybdenum nucleus of heavy water reactor. It is historically important because it's the first element to be artificially made.

Technetium

Technetium is a chemical element with the symbol Tc and atomic number 43. It is the first artificial radioactive material in the world. So it doesn't exist in the real world naturally.

It is a silvery white metal, which is madeartificially.
