How did Thomson's discovery of neon isotopes lead to the discovery of neutrons?

∙ 10y ago
After bombarding with alpha particles some elements (e.g. Be) it was observed that a strange radiation is emitted; Chadwick in 1932 showed that this radiation has neutral particles with a mass similar to the mass of proton. The proposed name was neutrons.

∙ 10y agothe neons color helped identify the protons which is equal to electrons

Does lead isotopes have the same neutrons?
NO,each isotope has different number of neutrons why that? in isotopes the mass number is changed but atomic number(protons) still constant,thus the number of neutrons will be changed
What is the stable nucleus produced at the end of the decay steps in a uranium decay series?
Thorium, radium, radon, polonium, thallium, etc.
What is the chemical make-up of lead?
Lead is one of the elements. Therefore, if you have pure lead, its makeup is lead. Lead has 82 protons, 105 neutrons, and 82 electrons in its most common isomer.
How many neutrons are in the most common version of lead?
So 205 is the most common == == == ==
How do isotopes of an atom differ from each other?
Isotopes can either be stable or unstable. Unstable isotopes have an uneven number of protons and neutrons. Stable isotopes have the same number of protons and neutrons. The number of usual protons in an element is found in the atomic mass, but I won't go there. (hope this helps, this is what we're learning about in our science class)
How many neutrons does lead have?
It depends on the isotope (atoms of lead with different numbers of neutrons). There are three stable isotopes of lead:206Pb has 124 neutrons207Pb has 125 neutrons208Pb has 126 neutrons

How did the discovery of isotopes lead J.J. Thomson to the description of the neutron?
The neutron was discovered by James Chadwick.
What is the number of neutrons in an atom of lead?
Pb (lead) 82 protons 82electrons 125 neutrons
What is the stable nucleus produced at the end of the decay steps in a uranium decay series?
Thorium, radium, radon, polonium, thallium, etc.
Lead-210 and lead-206 are different of lead?
isotopes
What atomic number of the element lead indicates that each atom of has lead?
82 protons
What is the chemical make-up of lead?
Lead is one of the elements. Therefore, if you have pure lead, its makeup is lead. Lead has 82 protons, 105 neutrons, and 82 electrons in its most common isomer.
What discovery lead the scientists to question john daltons model of the atom and to favor jj Thomsons model?
JJ Thomson's discovery of electrons indicated that atoms were not indivisible.
How many neutrons are in the most common version of lead?
So 205 is the most common == == == ==

I cannot answer this question.
