Concept explainers
(a)
Interpretation:
Provide the formula of potassium hydroxide.
Concept introduction:
An ion is a group of atoms and atoms where the number of the proton is different from the number of electrons. A positive ion or a cation is known as where the proton’s numbers are greater than the electrons. A negative ion or anion is known as where a number of electrons are more than the number of protons.
When an atom donates an electron, it has a positive charge and when an atom accepts the negative charge then it has a negative charge.
Binary ionic compounds comprise two elements only in which one is cation and another is an anion. It is vital to know that while writing the name of a binary ionic compound always cation comes first.
Polyatomic ions are the ions which contain more than one atom. Like NO3- contain one nitrogen and three oxygen atoms. In the polyatomic ions, the atoms are generally bonded covalently to each other and thus stay together as a one charged unit.
