What equipment did James chadwick use to discover the atom?
James Chadwick used a cloud chamber and a polonium-beryllium source in his experiments to discover the neutron, which ultimately led to the discovery of the atomic nucleus. His work provided crucial evidence for the existence of neutrons, which are neutral particles found in the atomic nucleus.
What evidence did Thomson that his glowing beam contained negative particles?
The cathodic rays beam was deflected by the atomic nucleus.
What the atomic number of nucleus of atom?
what is the atomic number of the nucleus?
Is there one protons and nucleus in atom?
Yes, all atoms have a nucleus! The Nucleus is the part of the atom which holds the Protons and Neutrons, the Electrons orbit the "atomic nucleus". The atomic nucleus is different to the nucleus of a cell, which holds genetic information and allows the cell to operate. Answer above provided by Runehally16.
What is the difference of atomic number and atomic mass?
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
Who provided evidence for the existence of an atomic nucleas?
In 1911, the scientist Ernest Rutherford directed a beam of alpha particles (each one equivalent to a helium nucleus, with 2 protons and 2 neutrons) at a thin sheet of gold foil - many of the alpha particles (with a charge of +2) were deflected straight back, repelled by the positively charged atomic nuclei within the gold foil. This provided experimental evidence for the existence of the nucleus for the first time.
What was the evidence that electrons were negatively charged?
They are diverted by the positive atomic nucleus.

What is the atomic number of the nucleus?
The atomic number is the number of protons in a nucleus.
Neutron was discovered by?
The neutron was discovered by Sir James Chadwick in 1932. Chadwick conducted experiments that provided evidence for the existence of a neutral subatomic particle within the atomic nucleus, which he named the neutron.
What did Rutherford's backward deflection of alpha particle give evidence of an atom's?
Rutherford's backward deflection of alpha particles in the gold foil experiment provided evidence of an atom's nucleus. The deflection indicated that the majority of an atom's mass and positive charge is concentrated in a small, dense nucleus at its center, with electrons orbiting around it. This discovery led to the development of the nuclear model of the atom.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
What evidence did Thomson that his glowing beam contained negative particles?
The cathodic rays beam was deflected by the atomic nucleus.
What the atomic number of nucleus of atom?
what is the atomic number of the nucleus?
The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
Is there one protons and nucleus in atom?
Yes, all atoms have a nucleus! The Nucleus is the part of the atom which holds the Protons and Neutrons, the Electrons orbit the "atomic nucleus". The atomic nucleus is different to the nucleus of a cell, which holds genetic information and allows the cell to operate. Answer above provided by Runehally16.
How did you find out protons are in the nucleus?
The number of protons in the atomic nucleus is equal to atomic number.
