Which statement best explains why the atomic theory developed efficiently?
Scientists ignored all previous knowledge about atoms.
Scientists had used creativity in their investigations.
Scientists had only used standard methods of investigation.
Scientists repeated experiments to make sure the results were correct.
What else can I help you with?
Which statement best explains why most atomic masses on the periodric table are decimal numbers?
Most atomic masses on the periodic table are decimal numbers because they are weighted averages of the masses of all isotopes of an element, taking into account their relative abundance. Since isotopes have different masses, the atomic mass is typically not a whole number.
How did James Clerk Maxwell contribute to the atomic theory?
He developed the "ELECTOMAGNETISM"
How were the elements in the periodic table arranged?
By Atomic Mass
Who developed a new atomic model about five years after Thomson?
About five years after J.J. Thomson proposed his atomic model in 1897, Ernest Rutherford developed a new atomic model in 1911. Rutherford's model was based on his gold foil experiment, which demonstrated that atoms have a small, dense nucleus surrounded by orbiting electrons. His findings shifted the understanding of atomic structure, leading to the Rutherford model, which laid the groundwork for later developments in atomic theory.
Which statement describes James Chadwicks discovery He discovered that the atomic nucleus is a dense positively charged mass He discovered negatively charged atomic particles that were deflected by a?
an electrical neutral particle from the atomic nucleus
Which country developed the atomic bomb?
We developed the first working atomic bomb but, GER. made up the idea.
WHY DID SADAKO DEVELOPED LEUKEMIa?
She developed leukemia because of the radiation from the atomic bomb dropped by the United States during WW2.
Who developed the first scientific atomic theory?
john dalton developed the atomic theory , which he published in 1803
Atomic theory explains what?
Atomic theory explains that matter is composed of small particles called atoms, which are indivisible and retain their identity in chemical reactions. It also explains how atoms combine to form molecules through bonds and how these interactions determine the properties of matter.
What theory explains matter at sub-atomic levels?
That is Quantum Theory.
What theory explains matter at sub atomic levels?
That is Quantum Theory.
Which statement best explains why most atomic masses on the periodric table are decimal numbers?
Most atomic masses on the periodic table are decimal numbers because they are weighted averages of the masses of all isotopes of an element, taking into account their relative abundance. Since isotopes have different masses, the atomic mass is typically not a whole number.
What New Mexico town is known for being the site where scientists developed the first atomic bomb?
The atomic bomb was developed at Los Alamos.
Who was the US group that built the atomic bombs?
The Manhatten Project was the orginization that developed the atomic bomb.
Is the statement An atom consists of a dense nucleus surrounded by a cloud of electrons best described as a law or hypothesis or a theory?
The statement "An atom consists of a dense nucleus surrounded by a cloud of electrons" is best described as a theory in the field of atomic structure. The atomic theory explains the structure of atoms based on experimental evidence and scientific principles.
Who developed the idea of the atomic matter of nature?
Democritus
Who developed the project of atomic bomb?
Albert Enistein
