What is the cleavage to barium?
Barium is an element which does not occur in pure (native) form on Earth. The two most common minerals in which barium occurs are Barite (BaSO4) and Witherite (BaCO3). According to its entry on wikipedia, Barite has Perfect cleavage parallel to base and prism faces: {001} Perfect, {210} Perfect, {010} Imperfect. I am unsure what sort of cleavage Witherite has.
How many valence electrons does barium have?

What element reacts with fluorine and loses two electrons?
Beryllium, Magnesium, Calcium, Strontium, Barium and Radium
Which is more reactive fluorine or barium and why?
Fluorine would be the more reactive element because it needs to gain one electron. While Barium needs to gain two electrons. Thus it is easier to gain one than to lose two.
