Answer:
Step-by-step explanation:
Alkaline earth elements are a group of six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). These elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
The correct statement about alkaline earth elements is that they are metals with two valence electrons. They readily lose these two electrons to form cations with a charge of +21.
