The five main points of John Dalton's atomic theory are as followed: · Elements are made of tiny particles called atoms. · All atoms of a given element are identical. · The atoms of a given element are different from those of any other element. · Atoms of one element can combine with atoms of other elements to form compounds. · A given compound always has the same relative numbers of types of atoms. · Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together.

The weight in daltons of one atom of an element is?
equal to the atomic mass of the element expressed in daltons. It is essentially the mass of one mole of the element in grams.
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) .
If the atomic mass of oxygen is 16 and the atomic mass of hydrogen is 1 how do the current atomic masses compare to daltons?
Atoms are made up of protons, neutrons, and electrons. The atomic mass listed on the periodic table is an average of all the isotopes of an element, which includes the mass of the protons and neutrons. Therefore, the atomic masses listed for oxygen (16) and hydrogen (1) are in daltons.
What is the atomic mass of neon'?
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) .
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
What main feature of daltons atomic model was abandoned after thomson's discoveries?
The idea that atoms are indivisible.
How did daltons atomic theory lead to the different model scientists have today?
Dalton's theory was irrelevant to the total compensation of of the Atomic Mass.
How many daltons does one molecule of water have?
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).
How did thompsons experiment change daltons atomic model?
thomas discovered that the atom contained smaller particals called electrons
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.
