Yes, very safe indeed.
All the alkali metals will melt.
You would get an chemical form of salt or you can say alkali metal salt.
If Argon gas and Copper metal were mixed together, they would not react chemically because Argon is an inert gas and Copper is a stable metal. They would simply coexist without interacting with each other.
The alkali metal would have a subscript of +1 while the nonmetal from group 6A would have a subscript of -2 to balance charges.
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
The element 119 will be very probable an alkali metal.
Rubidium (Rb)
Rubidium.
No, in comparison to the rest of the metals, lithium (as an alkali metal) would be called a soft metal. All the alkali metals could be cut with a knife, but still retain properties of metals.
It would be the next Alkali Metal and would be placed under Francium.
Yes, francium is an alkali metal; the group contain lithium, sodium, potassium, caesium, rubidium and francium.
Cesium is a reactive soft metal that has a "valency" of 1 and forms ionic compounds. It is in group 1, the alkali metals
