Concept explainers
Interpretation:
From, the given information, orbital diagram of silicon is to be drawn and Hund’s rule and pauli exclusion principle needs to explain that helps in orbital diagram drawing.
Concept introduction:
Hund’s rule: Hund’s rule states that no electron will pair up in an orbital, unless and until each orbital of a given subshell contains one electron each or is singly occupied.
Pauli exclusion principle:
According to Pauli exclusion principle an orbital can not have both the electron in same spin. electrons will be either half positive(+1/2) or half negative spin(-1/2).
Answer to Problem 15STP
Hund’s rule states that the last two electronswill be placed in separate p-orbitals. While Pauliexclusion principal helps in determining that shared electronsin any given orbital must have oppositespins, as shown by up and down arrows.
Hund’s rule: Hund’s rule states that no electron will pair up in an orbital, unless and until each orbital of a given subshell contains one electron each or is singly occupied.
Pauli exclusion principle:
According to Pauli exclusion principle an orbital can not have both the electron in same spin. electrons will be either half positive(+1/2) or half negative spin(-1/2).
The electron configuration for silicon is 1s2 2s2 2p63s2 3p2.
With which and using Hund’s rule and Pauli exclusion principle, orbital diagram formed is:
Hund’s rule states that the last two electrons will be placed in separate p-orbitals as shown in 3p, each orbital of a given subshell contains one electron then pairing of electron takes places.
While Pauli exclusion principal helps in determining that shared electrons in any given orbital must have opposite spins, as shown by up and down arrows in each orbital.
