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.

Two atoms of group IA (e.g., sodium) and one atom of group IIA (e.g., calcium) are needed to react with a carbonate (CO3^2-) because group I metals form +1 ions (like Na^+), which can bond with one carbonate ion, while group II metals form +2 ions (like Ca^2+), which can bond with two carbonate ions. This completes the ionic bonding requirements of the elements involved.

How many magnesium atoms would be needed to react with one bromine molecule?
Two magnesium atoms would be needed to react with one bromine molecule. Magnesium has a +2 oxidation state, while bromine has a -1 oxidation state. This means that two magnesium atoms are needed to balance the charges when reacting with one bromine molecule.
What do atoms of elements in the same group of periodic table have in common?
The atoms of the elements in the same group have the same number of valence electrons. This means that they react with other elements in a similar way. For example group 1. All the atoms in group 1 react with water and oxygen, so they have to be kept in paraffin-oil. Another example is group 18. They don't react with anything. The atoms of the same row have the same electron shells.

What group of minerals will react with dilute hydrochloric acid?
Carbonate minerals, such as calcite and dolomite, will typically react with dilute hydrochloric acid by releasing carbon dioxide gas. This reaction can be used as a simple test to identify these minerals.

How many atoms of a Group 17 element would be needed to react with one atom of a Group 2 element Explain.?
Two atoms of a Group 17 element would be needed to react with one atom of a Group 2 element because Group 17 elements have a valency of 1, while Group 2 elements have a valency of 2. This means that for the two elements to form a stable compound, they need to share electrons in a 1:2 ratio.
