Oxygen

Oxygen #Everwhere

Oxygen was discovered in 1774 by Joseph Priestley in England and two years earlier, but unpublished, by Carl W. Scheele in Sweden.

It has a negative 2 charge

First Ionization Energy: 1314 kJ/mol Atomic Radius: 74 pm Ionic Radius: 140 (O2-)

All oxygen atoms have 8 protons, but the nucleus might contain 8, 9, or 10 neutrons. “Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.

It's commonly used for use to be able to breath

This is how we get that O!

When metals react with oxygen the metal oxides are formed. Metal oxides are basic which means that they form an alkaline solution when dissolved in water, turning litmus to blue color. When non-metals react with oxygen the non-metallic oxide is formed. Non-metallic oxides are acidic. They form acidic solution when dissolved in water, turning litmus solution to red colour.

You see it?... Of course you dont its a gas at room temperature

Whoever told you this was a metal they lied! It's a non-metal and it's in period 2 group 16

In 1772, Carl Wilhelm Scheele discovered that red-hot manganese oxide produces a gas.

Density = 1.429
