Cation is a positive ion, not an element; for metals the symbol is Mex+.
In ionic binary compounds, cations are positively charged ions that give up electrons to become stable. The type of cation present in a binary compound depends on the elements involved in the compound. For example, sodium forms Na+ cations while magnesium forms Mg2+ cations. Each cation has a different charge and properties based on its atomic structure.
Most of the time, but not always. We often see the common Ca2+ or Al3+ being metals but there are non-metal ones like H+ or H3O+
If four molecules of barium acetate dissolve in water, they would dissociate into a total of 8 barium cations (Ba2+) and 4x2=8 acetate anions (C2H3O2-). So, there would be a total of 8 + 8 = 16 ions produced: 8 barium cations and 8 acetate anions.
Almost any element, including the heavier noble gases, can form a molecular compound (if chelated cations are considered molecular as most chemists would), but the vast majority of such compounds are composed of nonmetals.

Metals generally form cations
Metals become cations in solution.
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.
Yes, group 1 and 2 elements can become cations when they form ionic bonds. Group 1 elements, such as sodium, readily lose one electron to become sodium cations with a +1 charge. Group 2 elements, such as magnesium, lose two electrons to become magnesium cations with a +2 charge in ionic compounds.
Metals typically become cations by losing electrons to attain a stable electron configuration. Transition metals and main group metals are common examples of elements that form cations.
Yes, water molecules are generally more strongly hydrated to trivalent cations compared to monovalent cations. This is because trivalent cations, having a higher charge and smaller ionic radius, create a stronger electrostatic field that attracts water molecules more effectively. The increased charge density of trivalent cations leads to a higher degree of hydration, resulting in more water molecules being associated with them.
Molecules are not elements. Elements make up molecules, though.
any (strong) electrolyte
Elements chemically combine to make molecules.
Alkaline-earth elements form cations.
Alkaline-earth elements 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.
