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.
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
Thorium, radium, radon, polonium, thallium, etc.
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.
An atom of the same element that differs in the number of neutrons is known as an isotope. Isotopes have the same number of protons and electrons, which means they belong to the same element and have similar chemical properties. However, their differing neutron counts result in different atomic masses and can lead to variations in stability, with some isotopes being radioactive. For example, carbon-12 and carbon-14 are both isotopes of carbon, with different numbers of neutrons.
The element with the largest number of neutrons per atom is typically isotopes of hydrogen, specifically tritium, which has one proton and two neutrons. However, when considering more stable elements, the isotope of lead, lead-208, has 126 neutrons and 82 protons, making it one of the elements with a high neutron-to-proton ratio. In general, heavier elements tend to have more neutrons than protons, but lead-208 is notable for its high neutron count.

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
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.

The neutron was discovered by James Chadwick.

The mass number of an element is the sum of its protons and neutrons in the nucleus. Since lead (Pb) has an atomic number of 82, the mass number would be the total of protons and neutrons in a lead atom, which can vary based on the isotope.
