What did Democritus contribute in 400BC?
Democritus, a Greek philosopher, is known for his theory of atomism, which proposed that all matter is composed of tiny, indivisible particles called atoms. He also believed in the existence of a void and that the universe was infinite and eternal. Democritus' ideas laid the foundation for our modern understanding of atoms and the nature of matter.
How does Rutherford's theory of atoms helped in the development of the modern atomic theory?
Rutherford's theory proposed that atoms have a dense, positively charged nucleus. This led to the understanding that atoms are mostly empty space with electrons orbiting the nucleus. This laid the foundation for the modern atomic theory, which further developed with the discovery of subatomic particles and the concept of atomic number.
What did Ernest Rutherford add to are knowledge of atoms?
Ernest Rutherford's gold foil experiment led to the discovery of the atomic nucleus and the proposal of the nuclear model of the atom. He demonstrated that atoms are mostly empty space with a dense, positively charged nucleus at the center. This helped pave the way for further understanding of atomic structure and the development of the modern atomic theory.
What is the atomic number and atomic mass of this element?
Atomic number is the number of protons. Atomic mass is (mostly) the sum of the masses of the protons and neutrons (more or less).
What must the atomic number also identify?
Atomic Number identifies the following:No. of protons (same as the atomic number)No. of electrons (mostly same as no. of protons)Approximate Atomic Mass (No. of neutrons are roughly equal to or near to no. of protons)
The state of matter of the interior of the sun and other stars?
The state of matter is mostly gas and plasma (free moving atomic parts).

Which body is mostly plasma a moon b earth c sun?
The Sun is entirely plasma, which is a form of matter in which the electrons have been stripped away from the atomic nuclei.The Earth and Moon are mostly rock.

Are gold atoms composed of mostly matter or empty space?
All atoms are mostly empty space, as the electromagnetic repulsion between atomic nuclei keep them from reaching each other (except under extreme pressure, as in the center of stars).
Why can we state that most of the volume of matter such as the tabletop you are writing on is actually empty space?
Most of the volume of matter, like a tabletop, is considered empty space because the atoms that make up matter are mostly empty space themselves. Atoms consist of a small, dense nucleus surrounded by electrons orbiting at a relatively large distance from the nucleus. So while matter may appear solid, it is mostly made up of empty space within the atomic structure.
Are there neutrons in a white dwarf?
Yes. A white dwarf is made mostly of electron degenerate matter, which consists of atomic nuclei surrounded by free electrons. The nuclei contain protons and neutrons.
Where atomic hydrogen present mostly?
At the suns and stars.
What type of science is atomic force microscopy?
"Atomic Force Microscopy involves using an atomic force microscope, which is a tool that allows scientists to scan and view matter at a closer level than previous microscopes. This technology would be helpful in biology, mostly though uses could be found in chemistry and physics as well."

What difference between a scientific theory and a scientific?
Mostly semantics. A "law" is a theory that can be expressed mathematically.
