Explain how electrons are arranged in an atom.

In areas referred to as electron shells, the electrons in an atom travel throughout the nucleus.

There is a maximum number of electrons that can exist in each electron shell.

The lower energy level is initially filled with electrons, and then we proceed to the second energy level and so forth.

The term "electron configuration" or "electronic structure" refers to the arrangement of electrons within an atom.

The first shell can hold a maximum of two electrons. The first shell can hold a maximum of eight electrons. For the first twenty elements, the third shell can hold a maximum of eight electrons.

Electrons are arranged in energy levels, or shells, around the nucleus of an atom. Each shell can hold a specific maximum number of electrons: the first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and so on. Electrons fill the shells starting from the innermost shell and moving outward, with each shell being filled before moving to the next. This arrangement is governed by the Aufbau principle, the Pauli exclusion principle, and Hund's rule.
