Alkaline earth metals are in the second group. Be is the first metal of them.
Beryllium is the first element in the alkaline earth metals.
Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88
Alkaline earth metals are found in Group 2
Look at the position of Pb in the periodic table and the postion of the Alkali Earth metals. Alkali Earth Metals are in noble-gas configuration when they are doubly charged cations. Lead however is on the right hand side, and would like to have more electrons to get into that stablest configuration; making the bonds in lead-compounds more covalent -and stronger- in nature. Insoluble compounds have lattice enthalpies higher than the enthalpy of solvation. Now since Alkali Earth metals like to be in ionic states; their compounds will dissolve in general more easily than the same compounds with lead, since usually the lattice energy of lead compounds is much higher (In case of insoluble compounds higher than the energy that would be released upon solvation, which thus doesn't occur).
Homosapiens. They were the first "persons" on Earth.
No, the first element, hydrogen, is not an alkaline earth metal. The first of those is Beryllium.
Beryllium is the first element in the alkaline earth metals.

Be; Beryllium Element #4
Alphabetically, the first alkaline earth metal is barium and the last is strontium.
An element with two electrons in its highest energy level is probably an alkaline earth metal. More specifically, it is likely magnesium or calcium, as these are the most common alkaline earth metals.
The element with atomic number 4 is Beryllium (Be). Beryllium is the first element in the Group 2 - Alkaline Earth Metals family. It has 4 electron sin two shells, with two electrons in each shell.
Helium is the first member and the most abundent element in the known universe

Most of the lanthanides are silvery-gray metals. Check the Related Links section for pictures of all of them.
The first rare earth element, yttrium, was isolated in 1794 by the Swedish chemist Johan Gadolin.
It is about first ionization energy. It is less than alkaline earth metals.
