they have the elements and they are in the same substances
no all metals do not react with hydrochloric acids
Metals all tend to lose electrons when they react, but aside from that there is a wide variety in the reacts metals undergo.
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
Hydrogen react with metals and hydrides are formed.
Uranium can react with the majority of non-metals (excepting noble gases); uraniun can form alloys with all metals.
how do metals react with oxygen
Many. All the alkali metals will react explosively with it. All the alkaline earths will also react extremely vigorously. Group 3 metals from Al and below will and many transition metals do also. Copper, silver and Gold do not.
No, inert metals as Gold, Platinum and Palladium do not react with hydrochloric acid.
No. First of all, the metal does not dissapear. When a a metal reacts with an acid it forms a corresponding salt, which usually then dissolves. Second, whther or not a reaction occurs depends on both the acid and the metal. Most metals will not react with a dilute weak acid. Some metals will not even react with most strong metals. Gold, platinum, and some platinum group metals will not react with acid except for aqua regia, a special mixture of hydrochloric and nitric acid. Ruthenium will not react with acid at all.
Such metals are Sodium and Potassium (and all the alkali metals).
All alkali metals (group 1) and most earth-alkali metals (group 2)
Metals loss electrons and nonmetals gain electrons.
