positive ions
Zn and Ca both have double positive (2+) ions: Zn2+ and Ca2+ but other properties are different.
The root word "valent" is referring to the valence of an atom or ion. The prefix "alio" means different. Two aliovalent ions are ions that have a different valence. In other words they don't have the same number of valence electrons. The converse of this word would be "isovalent", meaning that the two ions are of the same valence.
Ions, or charged elemental particles, differ only in the number of electrons that they have. Some are capable (under ordinary circumstances) of gaining or loosing multiple numbers of electrons, which affects the means in which they can form ionic compounds with other ions. Essentially, differently charged ions will bond with different ions of opposite charge.
Like-charged ions repel each other. Opposite-charged ions attract each other.
Alkalis are bases that contain hydroxide ions (OH-) and are soluble in water. This means they can create strongly basic solutions when dissolved in water. Other bases may not necessarily contain hydroxide ions and may not be as easily soluble in water.

it depends on the inter-molecular bonds between the atoms/ions/molecules

You cannot. Different ions have different molecular masses.
Ions can take part in chemical reactions because of their electric charge, which makes them attract or repel other charged particles. This charge allows them to interact with other molecules or ions to form new compounds through ionic or covalent bonding. Additionally, ions can facilitate chemical reactions by providing the necessary charge balance in a reaction.
It has dissolved ions in it.
Ions are charged particles formed by gaining or losing electrons, while polyatomic ions are charged groups of atoms that remain together and carry a net charge. Polyatomic ions contain multiple atoms bonded together, whereas ions can be a single atom or a group of atoms.
potatoes have salt and water which makes ions when are mixed. Ions are groups of atoms that make an electric net that has a positive and negative charge like a battery. Batteries charges things so why not a potato?
When substances are dissolved in water they create ions. A strong electrolyte is when separate ions are formed in water. Note that pure water does not conduct electric currents. But ionic water does. A strong electrolyte is merely a collection of ions that interact with each other.
In an ionic bond, oppositely charged ions are held together by the strong electrostatic attraction between them. The positive and negative charges attract each other, causing the ions to stick together and form a stable compound.
