All the rare earth elements are natural chemical elements (including prometium - element obtained also artificialy).
no they are not. actinide is not part of the transition metals.
All of the actinides are radioactive, and almost all are synthetic.
These elements are found after uranium.
Particle accelerators are often used to create most synthetic elements. These machines accelerate particles to high speeds and then collide them to form new elements through nuclear reactions.
These elements are nitrogen, oxygen and argon.
no they are not. actinide is not part of the transition metals.
Synthetic elements are obtained: - in nuclear reactors - as a result (in debris) of nuclear weapons explosions - with the aid of particle accelerators
Most elements on the Earth occur as oxides or silicates.
All of the actinides are radioactive, and almost all are synthetic.
Yes, most actinides are synthetic elements, meaning they are not naturally found on Earth and need to be created in a laboratory through nuclear reactions. The only exception is uranium, which is the only actinide that occurs naturally in significant quantities on Earth.

The most common element in the earth's crust is oxygen.
Mostly it is used to back national currencies as it is considered one of the rarest and most valuble elements on Earth.
No, most of the actinides do not occur naturally in Earth's crust. Actinides are a group of elements that are mostly synthetic or man-made through nuclear reactions. Only a few actinides, like uranium and thorium, occur naturally in significant quantities in the Earth's crust.
No, oxygen is not considered a trace element. It is one of the most abundant elements on Earth, making up about 21% of the atmosphere. Trace elements are present in much smaller quantities.
