Group IIA, also known as the alkaline earth metals, typically have a charge of +2 when they form ions. This is because they have two valence electrons, which they tend to lose in chemical reactions to achieve a stable electron configuration. As a result, elements like magnesium and calcium commonly form cations with a +2 charge.
What else can I help you with?
What is the charge for elements in group IIA?
The charge for all elements in Group 2A is +2.
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?
Group 2 elements of the periodic table have a 2+ charge and are reactive. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They readily form 2+ cations by losing two electrons in chemical reactions.
When all group IIA lose their valence electrons the remaining electrons configurations are the same as for what family of elements?
When group IIA elements lose their valence electrons, they form cations with a +2 charge and have the same electron configuration as the nearest noble gas in the periodic table, which is group VIIIA (noble gases).
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 group number is alkaline earth metals in?
Group IIA: beryllium, magnesium, calcium, strontium, barium and radium.
What metal is a variable charge metal?
Most of the variably charged metals are found among the transition metals. Groups IA metals are +1 and Group IIA are +2.
How do IA and IIA differ the other Group A elements?
base in my experience.... because of the gravity of the earth...
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)
What cation has 18 electrons and is in group IIA?
The cation with 18 electrons and in group IIA is calcium (Ca^2+). Calcium loses its two valence electrons to achieve a stable electron configuration similar to a noble gas.
Why does the ionization energy drop going from IIA to the IIIA group?
The ionization energy drops from group IIA (alkaline earth metals) to group IIIA (boron group) due to the increasing atomic size and the presence of additional electron shells. In group IIA, the outermost electrons are in the same shell and experience a strong effective nuclear charge, making them harder to remove. However, in group IIIA, the introduction of a new electron in a higher energy level results in increased electron shielding and a weaker attraction to the nucleus, thus lowering the ionization energy.
What are the elements in Group IIA on the periodic table?
The elements in Group IIA on the periodic table are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). These elements are alkaline earth metals and share similar chemical properties.
