Elements on the far left of the Periodic Table need to lose electrons when they ionize, giving them a positive net charge. Conversely, elements on the far right usually gain electrons with the negative charge acquired making them anions.
Because those elements on the left, metals, have weak electronegativity and donate their valance electrons to the elements on the right, nonmetals, which accept the electrons into their valance shells.
On the far left of the periodic table, the elements have one or two electrons more than the stable noble gas configuration, so it is energetically more favorable to lose electrons and hence become cations.
On the far right, the elements have one or two electrons less than the stable noble gas, so it is energetically more favorable to gain electrons and hence become anions.
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.
Elements from the group 2 of the periodic table form cations.
The elements on the left side are metals. They lose electron to form cations.
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.
Co,Ni makes cations of different colours. So they make easily identifiable compounds. Elements in the d group make colourful cations.
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.
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.
The elements on the left side are metals. They lose electron to form cations.

cations = positively charged ions
The elements of group 1 has 1 valence electron. They lose 1 electron to form cation.
They tend to loose electron. They form cations.
These cations have the electrical charge +1.
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.
Metals generally form cations
Co,Ni makes cations of different colours. So they make easily identifiable compounds. Elements in the d group make colourful cations.
