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?
Alkali metals (Group 1) and alkaline earth metals (Group 2) are the most reactive groups of metals. They readily lose electrons to form ions and participate in chemical reactions with nonmetals to achieve a stable electron configuration.
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.
Why are the alkaline earth metals less reactive hen the alkali metals?
The alkaline earth metals are in group 2 of the periodic table this means they have 2 electrons in each of their outermost energy 'shells'. The alkaline metals are in group 1 and only have 1 electron to lose in a reaction rather than 2. This means the alkaline metals react more readily.
What is in the second column of the periodic table?
Alkaline earth metals are placed in second column. The elements have 2 valence electrons.
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 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.
What groups are alkaline earth metals and the 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"]
