The Aufbau principle is a rule in chemistry that states electrons fill the lowest energy levels in an atom first before moving to higher energy levels. This principle helps explain the arrangement of electrons in an atom, with electrons occupying orbitals in a specific order based on their energy levels.
The energy levels of an atom hold electrons.
a sulfur atom has 3 energy levels. 2 on the first. 8 on the second and 6 on the third
the meaning of paramanu is atom. Atom is the smallest particles of matter
quantized, meaning they can only have certain specific values. This quantization results in distinct energy levels for electrons in an atom, leading to the emission or absorption of photons when electrons transition between these levels.
polyvalent atom
Bohr proposed that electrons orbit the nucleus of an atom in fixed, circular paths or energy levels. These paths are quantized, meaning electrons can only occupy specific energy levels and transition between them by absorbing or emitting energy. This formed the basis of the Bohr model of the atom.

Nuclear radiation can ionize atoms, meaning it can strip electrons from them. This can cause the atom to become unstable and potentially change into a different element through decay. Additionally, high levels of radiation can damage an atom's structure, leading to mutations and potential health risks.
In a normal radium atom, which has an atomic number of 88, there are seven energy levels (or electron shells) that can contain electrons. These energy levels are filled with electrons according to the Aufbau principle, with the outermost levels containing fewer electrons. Thus, all seven energy levels in a neutral radium atom contain at least one electron.
