(a) The particle which is formed by gain of electrons by an atom is called Anion.
(b) The particle which is formed by the loss of electrons by an atom is called Cation.
(c) The particle which is formed by the loss or gain of electrons by an atom is called Ion.
(d) A potassium ion has positive charge because it contains less Electrons than protons.
(e) A sulphide ion has negative charge because it contains less protons than electrons.
Explanation:
- There are two types of ions. They are cations and anions. Cations are the type of ions that have positive charge. Anions are the radicals or atoms that have a larger number of electrons.
- More number of electrons are present in anions than protons. For instance, bromide Br-, iodide I- and chloride ions Cl-. Here, the particle X is most likely be an anion because it has a greater number of electrons than the protons.
- Electrons are the negatively charged particles, which orbit the atom’s nucleus. Protons are the positively charged particles present inside the nucleus.
