There are 4.
S , P, D and F
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher energy levels.
The energy levels and orbitals the electrons are in
The period number tell about the energy levels occupied by electrons
Oxygen has 8 electrons, so it will have 8 energy levels.
The element that has electrons in the same number of energy levels as argon is krypton. Both argon and krypton belong to the noble gases and have their electrons arranged in the same number of energy shells, specifically three energy levels. Krypton has a total of 36 electrons, while argon has 18.
Electrons tend to settle in energy levels around an atom's nucleus. These energy levels are called orbitals, which can hold a specific number of electrons based on their energy. Electrons will fill the lowest energy levels first before moving to higher energy levels.
Electrons are arranged in energy levels or shells around the nucleus of an atom. These energy levels can accommodate a specific number of electrons, and electrons are distributed in these levels based on their energy. The electron configuration of an atom determines its chemical properties.
Electrons are the components of an atom that are arranged in various energy levels or orbitals. These energy levels are quantized and correspond to different distances from the nucleus, with each level accommodating a specific number of electrons based on their energy.

the period number tells which is the highest energy level occupied by the electrons
The element's period indicates the number of energy levels or electron shells that its electrons occupy. Each period corresponds to a new energy level being filled by electrons. Moving from left to right across a period, the number of energy levels increases by one as you go from one element to the next.
