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.
