Reactivity of Metals & when was it discovered? By: Amal Al Kuwari Class: 8D

Reactivity Potassium: Very reactive, the most reactive metal, it is very quick with cold water too. Aluminum: Not very reactive, will not react with water or steam Lead: Not very reactive, will not react with water or steam Gold: Not reactive at all, will not react with cold water or when heated in steam, or with sulphuric acid. That’s why we use gold for jewelry, not potassium, because Gold is not reactive at all.

Reactivity Series: It shows the metal in order from most reactive to least reactive.

Neutrons, Protons & Electrons Potassium: 21 neutrons,19 proton &19 electrons. Aluminum: 14 neutrons, 13 protons & 13 electrons. Lead: 125 neutrons, 82 protons & 82 electrons. Gold: 118 neutrons, 79 protons & 79 electrons.

Who discovered these metals: Potassium: it was discovered by sir Humphry Davy, on November 1807 Aluminum: it was also discovered by sir Humphry, on 1808 Lead: No one really is sure, but some people think that it was discovered by the Ancient Greeks, in Catalhoyuk – Turkey, during 6400 BC. Gold: It was discovered in Coloma, by James W. Marshall.

The Periodic Table

Who Discovered the Periodic Table: The periodic Table was discovered by Dmitri Mendleev, he is Russian. He discovered the Periodic table during year 1869.

Human Ingenuity Human ingenuity means the creativity of the human in inventing things. These presentation relates to Human Ingenuity by telling us who discovered the metals and who discovered the periodic table.
