I would say the strings section.
The nucleus is too large to be stable. There is the theory of grouping of nucleons into alpha particles inside the nucleus and thru oscillations of the nucleus one of these on one end of the nucleus can be repelled with a great enough force to push it out of the nucleus.
An alpha particle is identical to the nucleus of Helium atom
Radioactive decay happens to the unstable atom nuclei in its efforts striving to reach stability. The nucleus of any element atom should have specific neutron/proton ratio to be a stable nucleus. Also, the absolute number of protons should not exceed certain limit.For a nucleus with neutron/proton is higher than the stability ratio, two types of radioactive decay may occur to decrease the ratio in the nucleus in order to reach stability:radioactive beta decay: in which a neutron transforms into proton plus electron where the proton remains in the nucleus and the electron is emitted from the nucleus as beta radiationradioactive neutron decay: in which a neutron is emitted from the nucleus as neutron radiation (this transformation is relatively rare. Example of this transformation is the unstable Krypton-87)For a nucleus with neutron/proton is lower than the stability ratio, two types of radioactive decay may occur to increase the ratio in the nucleus in order to reach stability:radioactive proton decay: in which a proton in the nucleus transforms into neutron plus positron where the neutron remains in the nucleus and the positron is emitted from the nucleus as positive beta radiationproton attraction of one electron from the nearest orbit to the nucleus to form neutron that remains in the nucleus.For an unstable nucleus with number of protons exceeding the stability limit, the nucleus may reach stability with one or more of the above four nuclear transformations or by:fission of the nucleus into two or more smaller nuclei with emission of one or more neutrons (as the spontaneous fission of one of the plutonium isotopes).

A helium nucleus - more precisely, a helium-4 nucleus - is called an alpha particle. The corresponding decay would be called alpha decay.
Hydrogen. In classical atomic theory, it contains only a proton.
Electrons surround the nucleus of an atom. The classical model shows them circling but in fact, their position and path is more complicated. The nucleus is made up of protons and neutrons. Protein is a molecule, not a component of atoms.
In present classification all algae contain nucleus . In classical classification algae were of two types . 1 Blue green algae lack nucleus and 2 all other algae are eukaryotic and possess nuclei .
Niels Bohr's main concern or question was how electrons can exist in specific energy levels around the atomic nucleus without radiating energy and collapsing into the nucleus, according to classical electromagnetic theory.
Classical theory, also known as the planetary model of the atom, suggests that electrons orbit the nucleus in fixed, circular paths similar to planets orbiting the sun. This model explains the behavior of electrons by proposing that they have specific energy levels and move in stable orbits around the nucleus.
Repel one another Spiral into the nucleus Maintain their negative charge D.ALL THE ABOVE ////////////////////////////////////// D. is correct Thanks
Classical physics predicts that electrons orbiting the nucleus in atoms should continuously radiate energy and spiral inward, eventually collapsing into the nucleus due to electromagnetic forces. This prediction contradicts observations and the stability of atoms, which led to the development of quantum mechanics to explain the behavior of particles at atomic scales.
It would spiral into the nucleus, emitting x-rays all the way in. Matter would collapse.
Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics—as if they were tennis balls, for example—is not possible due to quantum effects. Every atom is composed of a nucleus and one or more electrons bound to the nucleus.
The nucleus can be found in the center of an atom. The electrons can be found in the 'surface' if an atom is considered to be a sphere.
No, electrons do not revolve around the nucleus of an atom in perfect circular orbits. Instead, they exist in certain regions around the nucleus called orbitals, which describe the probability of finding an electron in a specific area. The behavior of electrons is better understood using quantum mechanics rather than classical mechanics.
generally in normal condition it is possible, but it is effected by environmental changes like temperature, pressure, humidity etc.....also when a heavy nucleus comes within the range of revolving nucleus its speed changes according to its parameters.
