How do IA and IIA differ the other Group A elements?
base in my experience.... because of the gravity of the earth...
What are the elements in Group IIA on the periodic table?
Group 2 (IIA) - Alkaline earth metals: Be, Mg, Ca, Sr, Ba, Ra ns2
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.
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.
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.

group 2a are called the alkaline earth metals
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

The charge for all elements in Group 2A is +2.
