A possible extension is to hold a cold piece of metal or glass above the place where you burst the bubbles so that the water vapour that forms during the reaction condenses on the metal or glass. Place approximately 1 g of the magnesium pieces in the test tube, but do not add the hydrochloric acid until everything else is ready to be asseled.

WebElements Periodic Table » Calcium » reactions of elements

Calcium reacts slowly with water. This is in contrast with magnesium, immediately above calcium in the periodic table, which is virtually unreactive with cold water. The reaction forms calcium hydroxide, Ca (OH) 2 and hydrogen gas (H 2 ). The calcium metal sinks in water and after an hour or so bubbles of hydrogen are evident, stuck to the

How does calcium and fluorine bond together?

24/4/2020· How does calcium and fluorine bond together? A transfer of electrons occurs when fluorine and calcium react to form an ionic compound. This is because calcium is in group two and so forms ions with a two positive charge. Fluorine is in group seven so forms ions with a negative charge. Calcium ions have twice as much charge as fluoride ions.

How do metals react with water? - Quora

Answer (1 of 4): Alkali Metals A common characteristic of most Alkali metals is their ability to displace H2(g) from water. This is represented by their large, negative electrode potentials. In this event, the Group 1 metal is oxidized to its metal ion and water is reduced
