Solution

Types of ions: An element can form two types of ions-
Cation: When an atom loses its valence shell electron to achieve stability, it forms a positively charged ion, cation.
Anion: When an atom gains an electron to achieve stability, it forms a negatively charged ion, anion.
Reason to form Cation: As the element has electronic configuration 2,8,8,1, it prefers to lose the valence electron to achieve the stable completely filled valence shell with 2,8,8 configuration.
Hence, the symbol of ion of X is X⁺.
