Explanation

Oxidation is the loss of electrons during a reaction by a molecule, atom or ion.

Oxidation occurs when the oxidation state of a molecule, atom or ion is increased.

The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.

Explanation

The atomic number was discovered by Henry Moseley in 1910.

Henry Moseley was an English physicist.

Explanation

Dmitri Mendeleev, a Russian chemist, formulated the Periodic Table in 1869, arranging chemical elements according to their atomic number (number of protons in the nucleus) and chemical properties.

He organized the elements in a logical and systematic order.

This making it easier to predict their behavior and relationships.

Explanation

• Sound travels fastest in diamond, with a speed of approximately 12,000 meters per second (m/s).
• This is because diamond has a very high stiffness and density, which allows sound waves to propagate quickly through the material.

The speeds of sound in different materials:

• Air: 343 m/s
• Water: 1433 m/s
• Wood: 3300-3600 m/s
• Brick: 4176 m/s
• Steel: 6100 m/s
• Diamond: 12000 m/s
