Name the elements that DO NOT exist in a human body?
It seems like every element, whether Sodium or Chromium, Calcium or Carbon, every element from the exists or in our bodies. Elements are present in trace quantities or in Kgs in one form or the other.
Can anyone list out those elements from the Periodic table that are absolutely NOT found in our bodies, nor are required in even the minutest of quantities?

sure, there are similarities between the earth's make up and guy's. The crust is greater like human skin or layers of skin and muscle. The subterranean formations that outline caverns are like human bones. The vegetation is like human hair. The fauna and humanity is extremely like the (powerful and risky) micro organism. The mantle is extremely like the circulatory device. The middle is extremely like the guts. the ambience is extremely like the human air of secret and different emissions of the human physique like millimeter waves and warmth waves. The clouds are only like the human suggestions. the climate is the physique of suggestions of the earth. The geological activity is like human thoughts. a minimum of that's how I surmise. however the factor is that God creates especially everyday varieties that is discerned in possible completely various issues.

Tc is used in some steels
Transuranics are present in minute quantities in the environment from above ground nuclear testing in the '40s and '50s.
