FAQs on History of Atoms Video Lecture - Chemistry Class 11 - NEET
| 1. Who discovered the concept of atoms? |  |
Ans. The concept of atoms was first proposed by the Greek philosopher Democritus in the 5th century BCE. He believed that everything in the universe was made up of tiny, indivisible particles called atoms.
| 2. How did John Dalton contribute to the development of atomic theory? | |
Ans. John Dalton was an English chemist who proposed the first modern atomic theory in the early 19th century. He suggested that all matter is made up of tiny, indivisible particles called atoms, and that each element is made up of atoms with a specific mass and chemical behavior.
| 3. What is the difference between an atom and a molecule? | |
Ans. An atom is the smallest possible unit of an element that retains its chemical properties, while a molecule is made up of two or more atoms that are chemically bonded together. In other words, atoms are the building blocks of molecules.
| 4. How did J.J. Thomson contribute to the understanding of the atom? | |
Ans. J.J. Thomson was a British physicist who discovered the electron in 1897. He proposed the "plum pudding" model of the atom, which suggested that atoms were made up of a positively charged sphere with negatively charged electrons scattered throughout.
| 5. What is the significance of Ernest Rutherford's gold foil experiment? | |
Ans. Ernest Rutherford's gold foil experiment in 1911 provided the first experimental evidence for the existence of a nucleus in the atom. He fired alpha particles at a thin sheet of gold foil and observed that some of the particles were deflected at large angles, suggesting that they had encountered a dense, positively charged center in the atom. This led to the development of the modern model of the atom, which has a small, dense nucleus at its center surrounded by electrons in orbit.
