It is magnesium.
Alkaline earth metals are in the second group. Be is the first metal of them.
None. The alkaline earth metal isotope with the fewest neutrons would be beryllium-7 with three neutrons and a half-life of 53 days.
The only alkaline earth metal that has a stable isotope with 20 neutrons is calcium.
BERYLLIUM :)
No. Selenium is a chalcogen. The alkaline earth metals are those in the same column as calcium.
