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
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
Are elements organized by atomic number or atomic mass?
On very early versions of the Periodic Table the elements were organized by atomic mass, because it was measurable and the concept of atomic number was unknown. After Rutherford and Bohr developed their model of the structure of the atom, the Periodic Table was reorganized by atomic number (which caused a few elements to swap positions).
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.
