What is the term for a black hole with no charge and no spin?

A black hole with no electric charge and no spin is a Schwarzschild black hole.

It is the simplest black-hole solution in Albert Einstein’s general relativity: a spherical, non-rotating object described by the Schwarzschild metric. The solution was found by Karl Schwarzschild in 1916, shortly after Einstein published the field equations, and was independently developed by Johannes Droste.

A Schwarzschild black hole is characterized by its mass alone. Its event horizon lies at the Schwarzschild radius, given by 2GM/c², where G is the gravitational constant, M is the mass, and c is the speed of light. The horizon is not a solid surface; it is a boundary beyond which signals cannot reach the outside universe.

A common mix-up is confusing the Schwarzschild metric with the black hole itself. The metric describes the spacetime geometry outside any spherical, uncharged, non-rotating mass, including ordinary stars and planets. The other options describe charged and/or rotating black-hole solutions: Kerr has spin, Reissner–Nordström has charge, and Kerr–Newman has both.
