Did Dalton model of the atoms include protons neutrons and electrons inside the atom?
no, because according to him an atom is a tiny indestructable sphere with mass on it.

What are the sub atomic particles for john daltons model?
In John Dalton's model, the subatomic particles are electrons, protons, and neutrons. Electrons are negatively charged particles found in the electron cloud surrounding the nucleus. Protons are positively charged particles located in the nucleus. Neutrons are neutral particles also found in the nucleus.
How many daltons does an element with 8 elecrtons and 8 neutrons and 8 protons have?
"Dalton" in this context has the same meaning as "atomic mass unit". Each proton and each neutron has one Dalton, while electrons have none. Therefore, the element in question has 16 daltons, and is in fact an atom of the most common isotope of oxygen, oxygen-16.
What subatomic particles used in Dalton's experiment?
Dalton used atoms composed of protons, neutrons, and electrons in his experiment. He proposed that atoms were indivisible and that elements were made up of these fundamental particles.
What was the point of Dalton atomic theory which is incorrect?
He said that atoms were indivisible, and we now know is not true because atoms are composed of protons, electrons, and neutrons, and that protons and neutrons are themselves composed of smaller particles. He also said that all of the atoms of the same element have the same mass, which we now know is not true because of the existence of isotopes.
Describe and name the parts of an atom?
Constituents of the atom:In the NUCLEUS:PROTONS - positively chargedNEUTRONS - neutrally chargedOrbiting the nucleus:ELECTRONS - negatively charged

What part of Dalton's theory of was disproved when scientists discovered that atoms contain protons electrons and neutrons?
John Dalton believed that atoms were the fundamental building blocks of matter, and that they could not be created, destroyed or split. However he was wrong, because atoms are made out of subatomic particles such as Protons, Neutrons and Electrons - and later still, it was discovered Protons and Neutrons too are made of even smaller particles.

What are the reasons why Dalton's atomic is not accepted these days?
One part of Dalton's atomic theory that is disregarded is the idea that all atoms in an element are uniform. The type of element is determined by the number of protons, and as such the number of neutrons can fluctuate. As well, Dalton's theory claimed that atoms could not be divided, but they are made of protons, neutrons, and electrons, and can be split apart into these particles.
What subatomic partices contribute to the mass of volume?
Electrons, due to their movement around the nucleus.
The electrons of an atom are found in the nucleus along with the protons?
No, actually the nucleus contains protons (which have a positive charge +) and neutrons which are neutral meaning they have no charge. The electrons are located outside of the nucleus in the electron cloud. To figure out more, you should research the findings of Rutherford and Dalton.

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.
Which of Dalton's postulates can be disproved today?
Dalton's postulate that atoms are indivisible has been disproved with the discovery of subatomic particles like protons, neutrons, and electrons. Additionally, his postulate that all atoms of the same element are identical has been disproved with the existence of isotopes.
