reactivity
Hydrogen react with metals and hydrides are formed.
Nitric acid reacts strongly with many metals.
Calcium nitrate don't react with metals; a possible reaction is with the water from the solution.
Hydrogen is not a metal. It is a non-metal.
I only know 3 metals that react with acids to produce hydrogen. They are Zinc, iron and magnesium. There are 3 acids which react with them: and It will produce hydrogen gas which is the lightest known gas and is flammable :)
No. Metals do not react with one another.
No.
Melals have free electrons. Hence metals react easily by giving electrons.
They metals are stored in oil to minimize the reactivity with air. When alkali metals react with air, they quickly tarnish after begin cut, they burn easily.
False. Many elements easily react, such as those in the Alkali Metals and Alkaline Earth Metals, VI, and halogen groups. Other elements react only under the right conditions, such as the transition metals. Some elements, such as the noble gases, do not react or react only under very stringent conditions.
Non metals form ionic bonds with metals. Non metals gain the electrons while metals loose. Alkali metals reacts with halogen family in efficient manner.
Hydrogen react with metals and hydrides are formed.
Because the electronegativity of metals is very different; the ability of metals to react with acids is also variable. But all metals can react with acids or mixture of acids at room temperature or at high temperature or pressures. An indestructible material don't exist.
how do metals react with oxygen
reactivity.
Yes. the reaction is exothermic and quite violent.
Alkali metals and halogens.
