Component 1 - History for Chemistry. Natalie Antis on …

Although Fluorine compounds were known of and used back in the 1600''s, it wasn''t pure Fluorine. Fluorine is so reactive that safely separating it wasn''t done until 1886 by Henri Moissan. Fluorine is actually the most reactive element . Fluorine attacks all metal, for example whenever Fluorine gas reaches steel wool, it bursts into flames.

Fluorine gas is placed in contact with calcium metal at

When fluorine gas reacts with calcium metal at high temperatures then it results into the formation of calcium fluoride. Since, calcium has 2 extra electrons as its electronic distribution is 2, 8, 8, 2. Whereas each fluorine atom needs one electron to complete its octet. Therefore, the chemical reaction equation will be as follows.
