∙ 11y ago1) All matter is made of atoms, which are indivisible and indestructible.
2) All atoms of a given element are identical in mass and properties.
3) Compounds are formed by a combination of two or more different kinds of atoms.
4) A chemical reaction is a rearrangement of atoms.

What is the approximate mass of a neon-11 atom?
The approximate mass is 11. Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, atomic mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
Jj Thomson's atomic theory?
what is atom
Whose investigation on properties of gases led him to propose an atomic theory of matter?
his observations led him to believe that gases are made of individual particles are very similar to the idia of the atom proposedby democritus
Why is the approximated atomic mass of an atom with 16 neutrons 15 protons and 15 electrons 31 Daltons?
The atomic mass is determined by the contents of the [atomic] nucleus - the sum of the protons and neutrons; in this case the atomic mass {also called the atomic weight} is 31. A dalton is the mass of a hydrogen atom, or ion: that is, a proton.
What was Niels bohr nickname for his atomic theory?
father atom
Why scientists accepted daltons atomic theory but not the idea of an atom proposed by the Greek philosopher?
the Greek Philosophers did not test their theory.
What was Benjamin Franklin's contribution to atomic theory?
Benjamin Franklin made several contributions to various scientific fields. In atomic theory, he was the first to propose how to measure the size of an atom.
How is the modern atomic theory different from Daltons atomic theory?
In Dalton's theory the electrons in the atom travel in a one layered orbital rotation around the nucleus, in the modern, or electron cloud, theory the electrons travel in a more radical patterned movement while still staying in their respected energy levels.
Who was the first person to propose the theory of the atom?
Democritus
What was the atomic theory about?
the structure of the atom
The fundamental particle of a chemical element according to Daltons theory is?
The atom. Considered by Dalton to be indivisible and indestructible.
Why was daltons model of the atom changed after Thompson experiment?
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within
How did thompsons experiment change daltons atomic model?
thomas discovered that the atom contained smaller particals called electrons

What was James chadwicks atomic theory?
the neutron atom
