Who Developed the 5 postulates of the atomic theory?
John Dalton
What are the sub atomic particles for john daltons model?
protons,neutrons and electrons are the sub atomic particles
How did Henry mosely rearrange the periodic table and why?
Before Henry Moseley, the periodic table was arranged in order of increasing atomic mass. However, this arrangement did not allow all the elements to be placed into groups of similar chemical properties. Moseley rearranged the periodic periodic in order of increasing atomic number which did have all the elements in their correct groups.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
no.
In the periodic table the elements are arranged in order of increasing?
In modern periodic table, elements are listed by increasing atomic number.
Are elements organized on the periodic table by increasing order of atomic number?
Yes, it is correct.
Who Developed the 5 postulates of the atomic theory?
John Dalton
What are the sub atomic particles for john daltons model?
protons,neutrons and electrons are the sub atomic particles
How does Daltons atomic theory explain the law of definite proportions?

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) .
How does atomic number explain the arrangement of the periodic table?
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
What is the approximate mass of a neon-11 atom?

Elements are organized in the periodic table by their?
The periodic table is a function of the atomic number.
What main feature of daltons atomic model was abandoned after thomson's discoveries?
The idea that atoms are indivisible.
Did daltons atomic theory include the idea that all atoms of all elements are the same size?
no.
Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
