As a consequence of the discovery of the nucleus by rutherford, which model of the atom is thought to be true?
a. electrons are distributed around the nucleus and occupy almost all the volume of the atom.
b. protons, electrons and neutrons are evenly distributed throughout the volume of the atom.
c. the nucleus is made of electrons and protons

Electrons are distributed in shells revolving around the nucleus and occupy almost all the volume of the atom.

In the nucleus of an atom, proton and neutron are present whereas electrons are present in shells revolving around the nucleus. Most of the volume of an atom has empty spaces in which shells are present in which electrons are moving.

The number of protons and electrons are the same in an atom but the number of neutrons are different so we can conclude that electrons are distributed in shells that are present around the nucleus.

As a consequence of the discovery of the nucleus, the model of the atom that is true is A. electrons are distributed around the nucleus and occupy almost all the volume of the atom.

It should be noted that neutron and proton can be found in the nucleus of an atom. Also, there are electrons that are present in the shells that revolve around the nucleus.

In the atom, the number of electrons and protons are the same but there are different neutrons. Lastly, most of the volume of the atom has empty spaces.

the answer is a for sure mark brainliest i had got this right on usatestprep

considering the question as per the attachment

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
