            <Attribute name="description">Pour déterminer la configuration électronique d&#39;un ion, identifiez d&#39;abord la configuration de l&#39;atome neutre. Ensuite, ajoutez ou retirez des électrons en fonction de la charge de l&#39;ion. Par exemple, pour trouver la configuration de l&#39;ion lithium (Li+), commencez avec le lithium neutre (1s²2s¹). Ensuite, puisque l&#39;ion du lithium a un électron de moins, retirez un électron de la sous-couche 2s pour obtenir 1s².</Attribute>

            <video:title>La configuration électronique des ions</video:title>
            <video:description>Pour déterminer la configuration électronique d&#39;un ion, identifiez d&#39;abord la configuration de l&#39;atome neutre. Ensuite, ajoutez ou retirez des électrons en fonction de la charge de l&#39;ion. Par exemple, pour trouver la configuration de l&#39;ion lithium (Li+), commencez avec le lithium neutre (1s²2s¹). Ensuite, puisque l&#39;ion du lithium a un électron de moins, retirez un électron de la sous-couche 2s pour obtenir 1s².</video:description>
