What is liquid in the family IIA?
There is none. All of the elements in group/family in group IIA/2 are solids at room temperature.
What group of the periodic table has a 2 plus charge and is reactive?
The second column from the left end of the table (Group IIA) consists solely of reactive elements, each with a charge of 2+. These are the Alkaline Earth Metals.
Why are two atoms of group IA and one atom of group IIA needed to react with carbonate?
Carbonate has a negative two charge (CO32-). Group 1 elements have a plus 1 charge, and group II elements have a plus 2 charge. In order balance the reaction so that the charge is balanced, the stoichiometry comes out 1 to 2 for Group 1 and 1 to 1 for the Group II.See the Related Questions for more information about balanced reactions and stoichiometry.
What is the trend in atomic size in the series of Group IIA elements Be through Ra?
Increases from top to bottom.
How many electrons do the elements in group IA of the periodic table have in their electron dot diagrams?
This is different for each period of group IIA in the P.T.Examples:Be in period 2 has 4 electrons, Ca in p.4 has 20and Ra in p.7 (down under in P.T.) has 88 electrons.The whole row: 4, 12, 20, 38, 56, 88 electrons, from top to bottom in group IIA
How do IA and IIA differ the other Group A elements?
base in my experience.... because of the gravity of the earth...
What is liquid in the family IIA?

What elements are in group 2a?
Beryllium, magnesium, calcium, strontium, barium and radium are the group IIA elements.

Which element has its outermost electrons in an S sublevel?
The elements belonging to Group IA and IIA.
What is the trend in atomic size in the series of Group IIA elements Be through Ra?
Increases from top to bottom.
What are the elements in Group IIA on the periodic table?
Group 2 (IIA) - Alkaline earth metals: Be, Mg, Ca, Sr, Ba, Ra ns2
Which group contains an element that is liquid at stp ia iia ib or iib?
The ONLY liquid elements (at STP) areMercury, Hg, in group 12Bromine, Br, in group 17Notations like ia, iia, ib or iib are not commonly in use, maybe in older books or periodic tables.
How many electrons do the elements in group IA of the periodic table have in their electron dot diagrams?
This is different for each period of group IIA in the P.T.Examples:Be in period 2 has 4 electrons, Ca in p.4 has 20and Ra in p.7 (down under in P.T.) has 88 electrons.The whole row: 4, 12, 20, 38, 56, 88 electrons, from top to bottom in group IIA
The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
Element M is a metal and its chloride has the formula MCl2 To which group of the Periodic Table does element M most likely belong?
2(IIA) Because The elements in Group 2 (IIA) are metals with a +2 oxidation state. Thus one atom of a Group 2 metal can combine with 2 atoms of chlorine (oxidation state = -1)
