Group 3 and lanthanides.
a group that forms anions with a -1 charge
Group 2, alkali earth metals.
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.
These cations have the electrical charge +1.
Elements from the group 2 of the periodic table form cations.
Only chemical elements are placed in the periodic table; cations are positive charged atoms.
Going across the periodic table from left to right ignoring the transition metals, +1 charge are for group IA, group IIA is for +2 then it skips to group IIIB with +3 charge, group VB is -3, group VIB is -2, group VIIB is -1 charge.
Cations are positively charged ions. Metals form cations.They are present on left side in periodic table.
Group IA: +1 charge Group II2: +2 charge Group IIIB: +3 charge Group IVB: +4 charge Group VB: -3 charge Group VIB: -2 charge Group VIIB: -1 charge
cations and anions
They are not found anywhere on the periodic table. Only elements are in the periodic table. A cation is a positively charged ion. Most of the elements that will form cations are found more or less in the middle of the table except for hydrogen.
The elements of group 1 has 1 valence electron. They lose 1 electron to form cation.
