What are J. J. Thomson's ideas called?
J. J. Thomson's ideas are called the "plum pudding model" of the atom, which proposed that atoms are composed of positively charged material with negatively charged electrons embedded within it. This model was later replaced by the more accurate "nuclear model" proposed by Rutherford.
What does the letter j stand for in science?
In science, the letter "j" does not typically represent a specific element or concept. It is simply part of the alphabet used to represent variables, quantities, or labels in equations, formulas, and scientific notation.
How many joules of heat are necessary to melt 500g of ice at its freezing point?
The heat required to melt ice is called the heat of fusion, which is 334 J/g. To melt 500g of ice, you would need 334 J/g x 500g = 167000 joules of heat.
What was the name of the project and lead scientist in the US effort to develop the atomic bomb?
The Manhattan Project was lead by Dr. J. Robert Oppenheimer.
Former scientific director of the Manhattan project who joined albert Einstein in opposing development of the hydrogen bomb?
J. Robert Oppenheimer was the former scientific director of the Manhattan Project and joined Albert Einstein in opposing the development of the hydrogen bomb due to its destructive power and potential consequences for humanity. Oppenheimer played a key role in the development of the atomic bomb during World War II and later became a vocal advocate for international cooperation and nuclear disarmament.
What were J. J. thomsons ideas called?
J.J. Thomson's ideas were called the plum-pudding model. This model described how electrons were evenly distributed throughout the atom.
What did J J. Thomsons experiment show?
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
What did sir j Joseph thomeson expand your knowledge about atoms?
sir jj thomsons was a brialiant english physics scientist, he observed the cathod in atom, later called electron, by CRT CATHOD RAY TUBE
What are J. J. Thomson's ideas called?
J. J. Thomson's ideas are called the "plum pudding model" of the atom, which proposed that atoms are composed of positively charged material with negatively charged electrons embedded within it. This model was later replaced by the more accurate "nuclear model" proposed by Rutherford.
What did J. J. Thomsons experiments provided evidence about an atom?
J. J. Thomson's experiments provided evidence for the existence of electrons as subatomic particles within the atom. This led to the plum pudding model of the atom, where electrons were embedded in a positively charged "pudding." These experiments laid the foundation for our understanding of atomic structure.
What did Thomsons experiments prove?
Thomson's experiments with cathode rays proved the existence of negatively charged particles, which he called electrons. This discovery provided evidence for the existence of subatomic particles and laid the foundation for the development of the modern atomic theory.
J j Thomsons experements?
In 1897, Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons. (See Figure 1.8 in the textbook for Thomson's experimental setup). From Maxwell's theory, he knew that charged particles could be deflected in a magnetic field
What particle did J. J. Thomson discover?
according to jj thomsons model of an atom,an atom consists of a positively charged sphere with electrons in it.however,it was later found that positively charged particles reside at the center of the atom called nucleus,and the electrons revolve around the nucleus.
What is a scientific word beginning with j?
joules
What is a scientific term that begins with a j?
Joule
What is the scientific name or taxonomic classification of the Rose flower F J Grootendorst?
The scientific or taxonomic name would be Rosa 'F. J. Grootendorst'.
Who opposed J J Thomsons atomic theory?
Some scientists who opposed J.J. Thomson's atomic theory included William Prout, Ernst Rutherford, and Max Planck. These scientists challenged aspects of Thomson's model, such as the presence of subatomic particles within the atom.
