How did Robert Millikan's oil drop experiment change scientists' view of the atom?
Robert Millikan's oil drop experiment, conducted in 1909, provided the first accurate measurement of the charge of the electron. By observing the behavior of tiny oil droplets in an electric field, Millikan demonstrated that electric charge is quantized, meaning it exists in discrete amounts. This finding reinforced the idea of subatomic particles and contributed to the understanding of atomic structure, leading scientists to recognize that atoms are composed of smaller charged particles. Millikan's work helped shift the scientific perspective toward a more nuanced model of the atom, incorporating the existence of electrons and their quantized nature.
Robert millikan's major contributions to the atomic theory?
Millikan: He discovered that the weight of an electron is 1840 times smaller than a hydrogen atom (atomis mass of 1) Thomson: Thomson was the first person to suggest the theory of the atom containing positive and negative particles, and demonstrated the latter which called electrons
Did Robert millikan discover subatomic particles?
No, Robert Millikan did not discover subatomic particles; rather, he is best known for his work on the oil drop experiment, which measured the elementary charge of the electron. His experiments provided crucial evidence for the quantization of electric charge and helped confirm the existence of electrons as subatomic particles. Although he contributed significantly to the understanding of atomic structure, the discovery of subatomic particles like electrons was attributed to other scientists, such as J.J. Thomson.
The work of which two scientists was most important in determining the mass of an electron?
The work of J.J. Thomson and Robert Millikan was crucial in determining the mass of an electron. Thomson's experiments in 1897 led to the discovery of the electron, establishing its charge-to-mass ratio. Later, Millikan's oil drop experiment in 1909 allowed for the precise measurement of the electron's charge, which, when combined with Thomson's findings, enabled the calculation of the electron's mass. Their contributions laid the foundation for our understanding of atomic structure.
How did milikans oil drop experiment change scientists view of the atom?
Millikan's oil drop experiment, conducted in 1909, provided the first precise measurement of the elementary electric charge. By observing the behavior of tiny oil droplets in an electric field, Millikan demonstrated that electric charge is quantized, existing in discrete units. This experiment bolstered the atomic theory by confirming that atoms contain charged particles, specifically electrons, and helped to solidify the understanding of atomic structure, leading to advancements in quantum physics. Consequently, it shifted scientists' views by establishing that atoms are not indivisible but composed of smaller charged components.
What was Robert Millikan's major contribution to the atomic number?
Any, Robert Millikan determined the electrical charge of electron.
When did Robert Millikan contribute to atomic theory?
Robert A. Millikan conducted many experiments throughout his long, distinguished career. If you're referring to the famous "oil drop" experiment that measured the quantum of electric charge, Millikan and Harvey Fletcher performed that particular one in 1909.
What were the key findings and significance of Robert Millikan's oil drop experiment in the field of physics?
Robert Millikan's oil drop experiment provided the first direct measurement of the elementary electric charge, demonstrating that it is a quantized quantity. This experiment was significant in confirming the existence of individual charges and contributed to the development of the modern understanding of atomic structure and the fundamental nature of electricity.
Robert A. Millikans contributions to the atomic theory?
Robert A. Millikan was the first to determine the electrical charge of the electron.
What is millicon's oil drop experiment?
The Millikan oil drop experiment was conducted by Robert Millikan in 1909 to measure the elementary electric charge (the charge of a single electron). In the experiment, tiny oil droplets were suspended in a chamber between two charged plates. By carefully controlling the electric field, Millikan was able to measure the charge on each droplet and determine the charge of a single electron. This experiment provided important evidence for the quantization of electric charge and contributed to the development of modern atomic theory.
