Why are group 1 metals called alkaine metals?
They are actually called the alkali metals. They are called the alkali metals because many of the compounds they form are bases (alkaline) and in pure form they will react with water to produce strong bases.
A substance that is dissolved in liquid is a what?
The dissolved substance is a called a solute.
What type of elements form positive ions and what are positive ions called?
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
Why is group 1 metals called alkali metals?
Group 1 metals are called alkali metals because they form alkaline solutions (pH greater than 7) when they react with water. They are highly reactive and easily lose their outermost electron to form positive ions, which makes them behave in a similar manner to the alkaline earth metals.
When a substance does not dissolve in water it is called what?
When a substance does not dissolve in water, it is called insoluble. This means that the substance does not break apart and mix uniformly with water to form a solution.
How was hydrogen Discovered?
Hydrogen was first discovered by Henry Cavendish in 1766 when he isolated it as a unique substance during his experiments on acids and metals. He observed that hydrogen released during the reaction of metals with acids produced a gas that burned easily.
Does gasoline form a new substance when burned in a engine?
no but cake does
When metals are burn in the air they form new substance what are these new substance?
it forms metal oxides
What is the substance called?
The hardest naturally occurring substance is called diamond. It is a form of carbon.

What kind of metals to ions form?
Metals tend to lose electrons, so they form positive ions called cations.
Do you expect ionic compounds to form between two metals?
No. Two metals or more will form a mixture called an alloy.
What is a substance called form from metal and a non meatal?
An ionic substance, or a salt
