NaF.NaF
Sodium Flouride - I think :/
The compound formed when sodium reacts with fluorine is sodium fluoride (NaF).
Sodium fluoride is an ionic compound with the formula NaF.
One substance that may contain sodium fluoride is common table salt. The chemical compound for sodium fluoride is NaF. The chemical is an inorganic compound.
Fluoride on its own is not a substance, it is an ion. Specifically it is a fluorine atom with an extra electron, giving it a negative charge. To make a complete substance it must be paired with a positive ion. The "fluoride" in toothpaste is usually sodium fluoride, a compound of sodium and fluorine. Fluorine on its own is an element.
The compound is sodium fluoride, which is formed by the combination of sodium (Na) and fluorine (F) atoms. Sodium fluoride is commonly used in toothpaste and water fluoridation to prevent tooth decay.
The total charge on a compound of sodium and chlorine, such as sodium chloride (table salt), is zero. This is because sodium (Na) has a +1 charge and chlorine (Cl) has a -1 charge, so they combine in a 1:1 ratio to form a neutral compound.
Pure NaF (sodium fluoride,not flouride)contains 45.23% fluorine by weight.

The ionic compound formed from NaH2PO4 is sodium dihydrogen phosphate. In this compound, the sodium ion has a +1 charge, and the dihydrogen phosphate ion (H2PO4-) has a -1 charge.
The compound is neutral.
Sodium chloride is neutral.
