Secondly, which group 1 element reacts the most vigorously? A. hydrogen gas is released B. Which reacts the most vigorously? Answer Save. Li and K are in group 1 - so the most reactive element of these two would be K because it's further DOWN the group. One interesting consequence of this is that tin (Sn) is often sprayed as a protective layer on iron cans to prevent the can from corroding. The Group 1 elements in the periodic table are known as the alkali metals. This reaction produces a metal hydroxide and hydrogen gas. How do they react with oxygen? Ca Sr Be Ba.

Related questions. Cesium reacts most vigorously with water because it is an alkali metal or a Group I element. Group 14: Carbon Family. Metals to the right of hydrogen in the electrochemical series, such as copper, silver and gold, do not react. For example, with careful control of oxygen, the oxide M 2 O (where M represents any alkali metal) can be formed with any of the alkali metals. (Potassium actually is the more reactive of the two) The reason is that potassium and sodium both lie in Group 1 of the periodic table, which contains all the alkali metals. In each case, the aqueous metal hydroxide and hydrogen gas are produced, as shown: (1) 2 X (s) + 2 H 2 O (l) → 2 X O H (a q) + H 2 (g) where X is any Group 1 metal. Help.

Pieces of it explode in water with increasing intensity going down the group. Fluorine is the most reactive non radioactive element on periodic table. At room temperature, oxygen reacts with the surface of the metal. As they are in the same group, they have similar chemical properties and will react with substances (including water) in a similar way. I'll assume your talking about a vigorous reaction and not just an oxidation that most metals will undergo in water. How do they react with Bromine? Calcium and magnesium are in Group 2, known as the alkaline earth metals.
