Elements of group 1 readily form ions having a charge of +1.
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.
This is the group 1 - alkali metals.
Any member of the alkali metals group, such as; Lithium, Sodium, Potassium etc.
The charge of group 7A elements when forming ions is -1 (negative 1).

Elements of group 1 readily form ions having a charge of +1.
The charge is 2-. The charges of elements in group one is 1+, group two is 2+, group 16 is 2-, and group 17 is 1-. The other elements you just have to memorize.
Group 1 elements are the alkali metals, which form ions wih a 1+ charge.
The charge that is usually formed by the elements in group 7A is 1-
none of the elements in the periodic table have a charge unless they gain (- charge) or lose (+ charge) an electron, or they can get delta charges which depends on what they are bonded too, that is what i learned in A2 chem a few monthes agoThe above information is absolutely correct... but here is a bit more information specifically for group 1A elements. All elements in group 1A can have a +1 charge as ions. Group 1A elements, such as sodium (Na), have 1 valence electron in their outer shell. When forming ionic compounds, sodium ions tend to donate this one electron to an element (in ionic form) that has 7 electrons in its outer shell. Thus, satisfying each atoms octet rule (haveing 8 electrons in their outer shell), as well as forming a neutral ionic compound.

This is the group 1 - alkali metals.
Potassium's charge becomes 1+ since it is Group 1A on the periodic table. The elements in that group all like to lose 1 electron to become more like the noble gases in Group 8A.
Group that tend to form -1 ions include group VIIA
