Answer:
1.eight valence electrons
Examples include hydrogen (H), lithium (Li), and sodium (Na). Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr). Oxygen, like all the other elements in group 16, has six valence electrons.
2.Beryllium and magnesium will show similar chemical reactions as calcium. Since these elements belong to same group II and also have two electrons in their outermost shell like calcium.
