sodium combines with fluorine to produce sodium fluoride an active ingredient in toothpaste in this form sodium has the electron configuration of which other element?
Sodium fluoride has the chemical formula NaF, which means it contains one sodium ion (Na+) and one fluoride ion (F-). The electron configuration of sodium (Na) is [Ne]3s1, meaning it has one valence electron in the 3s orbital.
The element with the same electron configuration as sodium is lithium (Li), which also has one valence electron in the 3s orbital. Therefore, sodium has the electron configuration of lithium in this form.
