The Lewis structure of sulfate ion is shown in the image attached.
The sulfate ion's Lewis structure consists of sulfur arranged in the center and four oxygen atoms connected by single bonds surrounding it. The structure's 32 valence electrons guarantee that every oxygen atom complies with the octet rule, while sulfur allows for an extended octet.
The resultant ion satisfies the stability requirements with a net charge of -2 and a complete octet for every atom. The bonding pattern and electron distribution in the sulfate ion are depicted in this representation.
