Small amounts of fluorine is good for human teeth and is in many city water supplies.
Almost all fluorine isotopes are Fluorine-19, which have 10 neutrons. Only trace amounts of Fluorine-18 can be found in nature.
Fluorine seems a likely answer
Fluorine.

Fluorine is an element. It occurs naturally.
the atoms it has
No. Life can exist without it.
An important element in standard toothpaste is Fluorine. Fluorine (F) is the first element in the Group 17(7) - Halogen family.
It is used in toothpaste and is a great tooth-cleaner.
Fluorine has a greater electronegativity than francium. Fluorine is the most electronegative element on the periodic table, meaning it has a strong attraction for electrons in a chemical bond. Francium, on the other hand, is one of the least electronegative elements and tends to lose electrons in chemical reactions.
Fluorine
Almost all fluorine isotopes are Fluorine-19, which have 10 neutrons. Only trace amounts of Fluorine-18 can be found in nature.
A fluorine atom has 9 protons and 9 electrons, which are the defining features of an element.
Fluorine is an element and barium is also an element. There is no fluorine in barium and not barium in fluorine.
Fluorine reacts violently with cold water, releasing toxic hydrogen fluoride gas and producing a mixture of hydrofluoric acid (HF) and oxygen. This reaction is highly exothermic and can be explosive.
Fluorine seems a likely answer
The valency of fluorine is -1.
