The halogen in period 6 is astatine. It is a radioactive element and is the rarest naturally occurring halogen on Earth.
Astatine is considered one of the rarest naturally occurring elements in the universe. It is part of the halogen group and is typically found in trace amounts in uranium and thorium ores.
Thallium is a naturally occurring element in the Earth's crust. It is not a man-made element.
Phosphorus is a naturally occurring element found in mineral deposits and living organisms. It is not man-made.
No, lithium is a naturally occurring element found in the Earth's crust. It is not manmade, but it can be processed and refined for various industrial and technological applications.
The rarest naturally occurring element on Earth is astatine. It is a radioactive element with a very short half-life, making it extremely rare and difficult to study. It is estimated that there is only a few grams of astatine present in the Earth's crust at any given time.

The heaviest naturally occurring element is uranium, and it has 92 electrons.
We look to the naturally occurring element uranium as a nuclear fuel.
Promethium is the rarest naturally occurring rare earth element in the lanthanide series. It is radioactive and not found in significant quantities in the Earth's crust, making it one of the least abundant elements on Earth.
