Can mobs spawn in 1 block high spaces?

Mobs cannot spawn on blocks that are less than a full block in height. Areas covered in bottom slabs are unable to spawn mobs, no matter the light level, although double slabs, top slabs and upside-down stairs are still spawnable.

Can mobs spawn 100 blocks away?
Hostile mobs spawn within a 128 block radius of the player. Mobs that move out of the 128 block radius will be despawned instantly. Passive mobs spawn closer to the player, and typically at a slower rate. Mobs will never spawn within 24 blocks of a player (with the exception of mob spawners).

Can mobs spawn at 7?
Mob Spawning
Hostile mobs spawn at night, and can only spawn on blocks with a light level of 7 or lower. An area can, therefore, be kept free of monster-spawning by illuminating it to a light level of 8 or higher.

Can mobs spawn in one block?
yes they can spawn on a single block, however the game mechanics make it so that any 10x10 area of "biome specific" blocks (e.g., corrupted stone, savannah grass etc.) will be regarded as a viable biome, thus why we are able to create mob spawners.
