What is the first element of the alkaline earth metals?
Beryllium is the first element in the alkaline earth metals.
Which member of alkaline earth metal is least reactive?
Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88
What group of elements is alkaline earth metals?
Alkaline earth metals are found in Group 2
Compare the solubilities of the lead compounds with those of the alkaline earth metals How are the solubilities similar and different?
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).
Who was the first person on earth to be creative?
Homosapiens. They were the first "persons" on Earth.
Is the first element in the alkaline earth group of elements?
No, the first element, hydrogen, is not an alkaline earth metal. The first of those is Beryllium.

Look at any periodic table: Beryllium #4 Magnesium #12 Calcium #20 Strontium #38 Barium #56 Radium #88
Alphabetically What are the first and last of the alkaline earth metals?
Alphabetically, the first alkaline earth metal is barium and the last is strontium.
What element is the first member of the rare earth metals?
The first member of the rare earth metals is lanthanum. It has the atomic number 57 and is commonly used in various industries such as electronics and optics.
What is the forth element?
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.
What is the first member of the noble gases and the second most abundent element in the universe?
Helium is the first member and the most abundent element in the known universe
What element is the first member of the lanthanide series?
Most of the lanthanides are silvery-gray metals. Check the Related Links section for pictures of all of them.
What is an element with a single electron in its highest energy level is probably what type of metal?
An element with a single electron in its highest energy level is likely an alkali metal. Alkali metals like lithium, sodium, and potassium have one electron in their outer energy level, making them highly reactive and likely to form ionic bonds.
Who discovered the first Rare EARTH Element?
The first rare earth element, yttrium, was isolated in 1794 by the Swedish chemist Johan Gadolin.
What element was first discovered somewhere other than earth?
Technetium (element 43) was the first element to be discovered on Earth that was not found naturally in nature. It was synthesized in a laboratory by Italian scientists in 1937.
Is the ionization energy of alkali metals larger or smaller than the alkaline earth metals in the same period?
It is about first ionization energy. It is less than alkaline earth metals.
