Answer:

Name of Scientists who contributed in chemistry: Dmitri Mendeleev, Marie curie, Robert Boyle, Prafulla Chandra Ray, Linus Pauling, Ernest Rutherford, etc.

Explanation:

1. Dmitri Mendeleev:

• He was the Russian chemist.
• He is known for contributing in forming of periodic law and using in putting elements in periodic table.
• He put periodic table's elements in the groups based on their chemical and physical properties.
• Due to this, he could predict the elements and their properties which were yet to be discovered.
• He predicted three elements which were yet to discovered, i.e., Eka-Aluminum (discovered element-Gallium), Eka-boron (discovered element-Scandium) and Eka-silicon (discovered element-Germanium).

2. Marie curie:

• Marie curie discovered metallic elements Radium and Polonium.
• She Isolated pure state of metallic Radium for the first time.
• She carried out the first research on cancer tumors with radiation therapy.
• She won Nobel prize for her contribution in chemistry as well as physics.
• She is the only person who won Nobel prize in both physics and chemistry.

3. Robert Boyle:

• Boyle is known as a founder of Modern chemistry
• Robert Boyle Discovered the Boyle's law of gas which is as below:

"At constant temperature, the absolute pressure is inversely proportional to the volume of a fixed amount of gas."

• He also developed the methods to determine purity of compounds and chemicals.

4. Antoine Lavoisier:

• 'Antoine Lavoisier' is known as 'Father of Chemistry'.
• He discovered that mass is conserved in a chemical reaction.
• He proved the law of conversion of mass.
• He gave the oxygen theory of combustion.

5. Prafulla Chandra Roy:

• Prafulla Chandra Roy was Bengali-Indian chemist.

• He is known as Father of Chemistry of India.
• He discovered Mercurous nitrite chemical compound.
• He was the founder of India's first pharmaceutical company: 'Bengal Chemicals and Pharmaceuticals'.
