The periodic table currently contains 118 elements, ranging from hydrogen (atomic number 1) to oganesson (atomic number 118).
Linus Carl Pauling
He is an American-based chemist, chemical engineer, and biochemist. He won Nobel prizes for his chemistry work.
🏆 Two Nobel Prizes: He received the Nobel Prize in Chemistry in 1954 for his research on the nature of the chemical bond and its application to the elucidation of the structure of complex substances. He also received the Nobel Peace Prize in 1962 for his efforts to promote nuclear disarmament.
Chemical Bonding: He developed the concept of electronegativity, which helped explain the strength and polarity of chemical bonds.
Molecular Structure: He used X-ray crystallography to determine the structures of complex molecules, such as proteins and DNA.
Quantum Chemistry: He applied quantum mechanics to the study of chemical bonding and reactions.
Nuclear Chemistry: He investigated the structure of the atomic nucleus and the nature of nuclear forces
John Dalton
Besides being a renowned chemist, he was also a popular microbiologist and meteorologist. He identified color blindness.
Law of Partial Pressures: Dalton also formulated the law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual gases. This law is important for understanding the behavior of gases in mixtures
Dalton was also the first person to describe color blindness, a condition that he suffered from. He published his observations on color blindness in 1794, and the condition is now known as Daltonism in his honor.
Atomic Theory: John Dalton's most significant contribution to chemistry was his atomic theory, which he proposed in 1803.
This theory states that all matter is composed of tiny, indivisible particles called atoms. It also proposed that atoms of the same element are identical in mass and properties and that atoms of different elements combine in simple whole-number ratios to form compounds.
Marie Curie (1867-1934)
She was the first lady who won Nobel Prizes for physics and then chemistry. She is known for her discoveries of radioactivity.
There is a lot to learn in chemistry, which makes the subject a versatile phenomenon. Further, with the works of renowned chemists, the subject has been given a proper shape, and it still holds a lot of discoverable facts, which is why it is one of the most indulging subjects as well.
Nothing in life is to be feared; it is only to be understood.
