The question is..
In which of the following atoms is the 3s orbital closet to the nuclues...
Br,Cl,At,I
first off how are those atoms in the 3s orbital? I thought the 3s orbital where Na and Mg?
An orbital is a region of space around an atomic nucleus where there is a high probability of finding an electron.
An s orbital is a spherical shape and can hold a maximum of 2 electrons, while a p orbital is dumbbell-shaped and can hold a maximum of 6 electrons.
Electrons fill orbitals in order of increasing energy, starting with the lowest energy level and moving up to higher energy levels.
The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers, meaning they must have opposite spins. This principle helps to explain the unique arrangement of electrons in atoms.
Energy levels correspond to the different shells of an atom, while orbitals correspond to the subshells within those shells. Each subshell has a different energy level, with the s subshell being the lowest and the f subshell being the highest.
