(That's what wikipedia is good for, dummy)
The nucleus of an atom contains protons and neutrons. Different amount of neutrons- Isotopes. Different amount of protons- Different element.
All elements have neutrons and protons within the nucleus.
The smallest unit that shows the properties of an element is an atom, and yes, an atom has protons and neutrons in the nucleus.
All the isotopes of a chemical element have the same atomic number, number of protons and number of neutrons.
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
The nucleus is made of protons, neutrons and electrons. These element move in and out of the nucleus depending on the external environment.

Yes, 25 protons and 30 neutrons form the nucleus of Manganese's most stable isotope.
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
Protons and neutrons ar fomed from quarks and are not considered as fundamental particles; they are components of the atomic nucleus.
Each element has a different number of protons and neutrons. So it changes for each element.
There is no simple answer.The mass of a nucleus depends on the number of neutrons and protons in the nucleus. The number of protons in the nucleus depends on the element. Moreover, the number of neutrons can vary between isotopes of the same element.
Assuming that two neutrons and two electrons are also added, the atomic number would shift from 80 to 82, resulting in lead. If the neutrons or electrons were not added, it would be the radioactive isotope, lead-206.
the total number of protons and neutrons in the nucleus.
