Electrons in metals are delocalized and in a free movement.
No. Metals liberate hydrogen gas from acids.
When dilute acids and metals are mixed you will get Hydrogen gas and salts
Several gasses can react with metals, but due to the fact that you are asking for a single gas, the most likely answer that you will be looking for is Oxygen. Oxygen reacts with many metals (and non-metals).
neither. it is a noble gas
H2 gas
Hydrogen gas.
Oxygen (O2) is the gas.
metals as in elements. or like zinc. or something. from my knowledge, magnets, other metals (sometimes), gas, && liquid.
Its a gas
Yes.Yes.Yes.Yes.
Alkali metals and alkaline earth metals will form ions (by losing 1 and 2 electrons respectively) with noble gas electron configuration.
Hydrogen gas, H2
