Who is model of the atom has no subatomic particles?
The model of the atom with no subatomic particles is the Dalton model, proposed by John Dalton in the early 19th century. In this model, atoms were considered indivisible and the smallest building blocks of matter. Subatomic particles like protons, neutrons, and electrons were not discovered until much later.
Who made the first model of the subatomic particles?
The first model of subatomic particles was proposed by J.J. Thomson in the late 19th century. He discovered the electron and suggested that atoms were made up of a positively charged "pudding" with negatively charged electrons scattered throughout.
What subatomic particles represented the plums?
The plums in the famous "plum pudding" model of the atom represented electrons, which are negatively charged subatomic particles.
What are the three subatomic models?
The three subatomic models are the plum pudding model, the nuclear model, and the current model known as the quantum mechanical model. These models describe the structure of the atom and the arrangement of subatomic particles within it.
What was the first model of the atom was developed through?
The first model of the atom was developed through the discovery of subatomic particles such as electrons, protons, and neutrons. This led to the development of the planetary model of the atom proposed by Niels Bohr in 1913.
Why is the ring model of atomic structure useful?
It shows the electron shell and charges on the subatomic particles.
What are the weights of the subatomic particles?
I think you probably mean the mass of the classical subatomic particles, Proton, Neutron and Electron. From memory, the mass of the proton and neutron are almost the same and approximately 1.6 x 10-24 grams while the mass of an electron is about 0.9 x 10-28 grams. In the Standard Model of subatomic particles, there are very many more particles than these three and their masses are best looked up in tables. Some of the masses of subatomic particles have not yet been determined (neutrinos) and one of the theoretical particles has not yet been shown to exist at this time (Higgs boson).
What subatomic particle did Bohr discover?
Bohr was not the discoverer of a particle.
What are properties that vary among subatomic particles?
The atom is the smallest part of matter that represents a particular element. For quite a while, the atom was thought to be the smallest part of matter that could exist. But in the latter part of the 19th century and early part of the 20th, scientists discovered that atoms are composed of certain subatomic particles and that, no matter what the element, the same subatomic particles make up the atom. The number of the various subatomic particles is the only thing that varies. Scientists now recognize that there are many subatomic particles (this really makes physicists salivate). But in order to be successful in chemistry, you really only need to be concerned with the three major subatomic particles: Protons Neutrons Electrons
What are the sub atomic particles for john daltons model?
In John Dalton's model, the subatomic particles are electrons, protons, and neutrons. Electrons are negatively charged particles found in the electron cloud surrounding the nucleus. Protons are positively charged particles located in the nucleus. Neutrons are neutral particles also found in the nucleus.
Who is the first scient who made the model of an atom?
THE FIRST SCIENTIST WAS RUTHERFORD.
What major changes occurred from Democritus's model to Thomson's model?
Democritus proposed the first atomic theory, suggesting that matter is made up of indivisible particles called atoms. Thomson's model, proposed in the late 19th century, introduced the idea of the atom as a sphere with embedded electrons, challenging the indivisibility of atoms seen in Democritus's model and suggesting the presence of subatomic particles. Thomson's model also laid the groundwork for the later development of the more accurate planetary model of the atom by Rutherford.
