What else can I help you with?
Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.
Which actinide element is the heaviest that occurs natturally on earth?
URANIUM (:
What element is the heaviest actinide that occurs natrually on earth?
Uranium
What actinide element is the heaviest that occurs naturally on earth?
Uranium because uranium has the highest atomic number, 92, of the natural, actinide elements. Elements higher than 92 are man-made elements. Check the periodic tables to see for yourself!~
What element is the lightest actinide that occurs naturally on earth?
The lightest naturally occurring actinide on Earth is thorium, which has the atomic number 90. It is a naturally occurring radioactive element found in small amounts in soil and rocks.
What is the heaviest element known to exist naturally on earth in quantities detectable by purely chemical test methods?
Now californium is considered as the heaviest naturally occurring chemical element.
What is the heaviest naturally occurring metal on Earth magnesium or radium or plutonium?
Radium: Plutonium does not occur naturally, and magnesium has a low density for a metal.
Are most of the actinides synthetic elements?
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.
Does zirconium occur naturally on earth?
Yes, zirconium occurs naturally on Earth as a mineral called zircon. It is commonly found in igneous and metamorphic rocks and is also present in beach sands. Zirconium is the 18th most abundant element in Earth's crust.
What is nonliving substance that occurs naturally in Earth's crust?
Rock.
What is the difference between Rock minerals?
A mineral is a solid that occurs naturally in the Earth. A rock is a solid combination of minerals which also occurs naturally.
Is zinc extracted or processed?
extracted, it is a mineral that occurs naturally in the earth.
