What element is the first member of the alkaline earth metal?
Alkaline earth metals are in the second group. Be is the first metal of them.
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.
What element is the first member of the alkaline earth metal?
Alkaline earth metals are in the second group. Be is the first metal of them.
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.
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.
Which 2 groups of metals are the most reactive?
1. alkaline metals 2. alkaline earths metals
What is an element with a single electron in its highest energy level is probably what type of metal?
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.
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.
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
First ionisation energies of alkaline earth metals are higher than those of alkali metals?
Yes, they are.
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 groups are alkaline earth metals and alkali metals in?
the first and second groups. alkaline earth metals: group IIA (2) [It consists with "Be,Mg,Ca,Sr,Ba,Ra"] alkali metals: group IA (1) [It consists with "Li,Na,K,Rb,Cs,Fr"]
