Arsenic and mercury, both commonly occurring metals present in rocks, can kill humans immediately. Especially if vaporized. Uranium can kill and disable quickly in high enough concentrations.
Also, keep in mind it’s a plot device about a fictional flying space alien with laser eyes. It doesn’t need to follow the laws of physics.

If that was the case, Superman would have died more than once.

I only know of 1 time and kryptonite wasn’t even used. Doomsday just best him to death.

Depending on the writer, there are three consistent kryptonite types:
Green weakens him, but overall it doesn’t kill him. Strips his powers, makes him faint or just weak and nauseous.
Blue just takes his powers away either temporarily or permanently
Red intoxicates him or enhances his impulsiveness/brashness
There are others, but they kind of shift of just don’t exist in the main canon

I remember in a Lobo comic, Lobo grips a chunk of Kryptonite in his fist as he punches straight thru Superman’s chest and heart, right out the other side! Don’t fuck with the Main Man!

Did he die though?
