WHAT ELEMENT IS LIQUID OR SOLID IN A LAB, SILVER,FORMULA OF THIS ELEMENT IS XCl,LOW DENSITY,LOW BOIL POINT,?

Question

aTOMS OF THIIS ELEMENT WILL BE OXIDIZED BY Al3+ IONS

Answer 1

To note: Something with a formula XCl is not an element, it is a compound.

Is your teacher is looking for an element, X, which can form a compound XCl ?

And, is the low b.p. referring to the element, X, or the compound XCl?

I would guess that X is one of the Group 1A elements (Li, Na, K, Rb, Cs, Fr). All of these exist (not sure about Fr) in thier elemental form as a silvery metal. Li and Na are both relatively low density elements (Li = 0.54, Na=0.97). But, neither the m.p. nor the b.p. for either element are within normal "room temp".

The answer must lie in what Al cations will oxidize, and I just don't recall that off the top of my head.

Answer 2

Sounds like Francium.
Mercury doesn't work with the low density part.

Answer 3

Elements don't have chemical formulas, they have chemical symbols.
