What is an alkali metal which would melt?
All the alkali metals will melt.
What are the reactions with alkali metals and water like?
1) Alkali metals are stored in oil to minimise reaction with oxygen or water, it's a physical barrier towards air but the alkali metals still gradually corrode a traces of oxygen and water diffuse through. The reaction of alkali metals with water gets more violent for elements lower in the group e.g. (Li < Na < K < Rb < Cs). Adding them to water will cause an explosion due to the extremely exothermic nature of reaction, and can be rather dangerous and some alkali metals can react violently with just moisture in the air. Most of the alkali metals float on the top of the water, depending on how big the alkali metal is determines the size of the reaction this is because they're less dense that water itself and also during the reaction the alkali metals give of hydrogen gas which is quite flammable. Alkali Metal + Water » Metallic Hydroxide + Hydrogen The francium would be like any other alkali metal, it would be very violent like the other alkali metals.
Which Alkali metals would undergo the least exothermic reaction with chlorine?
Cesium would undergo the least exothermic reaction with chlorine among the alkali metals. This is because cesium is the most reactive alkali metal, so it requires more energy to form a compound with chlorine compared to the other alkali metals.
What alkali metal reacts most slowly with water?
Lithium (Li) is the alkali metal that reacts most slowly with water. It is the first alkali metal and thus, the least reactive of the group. The lithium metal is seen to dart around the surface of the water with some whzzing and effervescence of hydrogen gas. The heat produced from the reaction may not be sufficient to ignite the hydrogen gas, resulting in no flame, compared to other metals like sodium and potassium where the reaction would be more violet and the metal would quickly catch fire.
What happens when any of the alkali metals react to chlorine?
You would get an chemical form of salt or you can say alkali metal salt.
What subscripts would most likely be used if an alkali metal and a nonmetal from group 6A formed an ionic compound?
The alkali metal would have a subscript of +1 while the nonmetal from group 6A would have a subscript of -2 to balance charges.
What happens when you add an alkali to an alkali?
A chemical reaction. Acid + alkali = salt + water eg H2SO4 + 2NaOH = Na2SO4 + 2H2O Sulfuric acid + Sodium Hydroxide = Sodium Sulfate + water Whan as acid meets an alkali they create a chemical reaction. If there is an acid and you add a weak alkali you should bring it down to neutral.
Which alkali earth metal has the smallest atomic radius?
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
What reaction will you be taking out if your metal is copper?
what reaction would be taken out if you had copper as your metal
What does the odor of sodium smell like?
Sodium is an alkali metal and it has no odor. However, taking a piece of sodium nearer to the nose to examine the smell would be dangerous. Further, none of the alkali metals have a smell.
Would element 119 be a metal nonmetal or metalloid?
The element 119 will be very probable an alkali metal.
What are the reactions of Group 1 elements with Br2?
Group 1 elements (alkali metals) react with bromine (Br2) to form ionic compounds known as metal bromides. The general reaction involves the alkali metal displacing the bromine from its diatomic form to form the metal bromide and release diatomic bromine gas. The reaction is highly exothermic and can be violent, especially with more reactive alkali metals like sodium and potassium.
