Answer:
hydrogen gas
Explanation:
Zn + 2HNO3 ------ Zn(NO3)2 + H2⬆️
These metals are silver and soft, much like the alkali metals of Group 1. These metals also react with water, though not as vigorously. Beryllium, interestingly, does not react with water. Each alkaline earth metal has two valence electrons.
Hope this helps :)
Yes, in a way it would, as it would rose out of its container and drift away/apart.
If it is an ionic bond (metal with nonmetal) the electrons will be transferred. If it is a covalent bond (nonmetal with nonmetal) the electrons will be shared. It depends on the electronegativities; the closer the electronegativities of the two atoms, the more covalent the bond is, making the electrons more equally shared. But if the electronegativities are very different, one atom (the nonmetal) will pull the electrons from the other (the metal).
