Question

Give the ground-state electron configuration for silicon. Express the complete electron configuration using superscripts where appropriate. For example, the configuration for Li would be entered as 1s^22s^1.Give the actual ground-state electron configuration for copper.Express the electron configuration using superscripts where appropriate. For example, the configuration for Li would be entered as 1s^22s^1.

Answer 1

Si 1s^2 2s^2 2p^6 3s^2 3p^2

Co (actual) 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^1

Co (expected) 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^9

i'd be careful with Copper. i listed the actual e- configuration for an element and lost points cause they were looking for the expected e- configuration

Answer 2

Silicon has an electronic configuration of 1s² 2s² 2p² 3s² 3p².

Using the noble gas notation, the electronic configuration of silicon is  [Ne]3s² 3p².

Copper  has an electronic configuration of 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁹.

Using the noble gas notation, the electronic configuration of copper is  [A r] 3d¹⁰ 4 s¹.

What do you mean by the electronic configuration ?

Electronic configuration is  the systematic distribution of electrons in the various atomic orbitals.

In the electronic configuration, electrons are distributed in various energy levels (various shells) of an atom, such as K shell, L shell, M shell, N shell.

Electronic configuration is defined as the distribution of electrons into the orbitals of an atom.

In this way the electronic  configurations  of silicon and copper are represented  .
