Which actinide element is the heaviest that occurs natturally on earth?
URANIUM (:
Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.
What is the heaviest actinide that occurs naturally 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.
Consequence of actinide contraction on actinide element?
as a consequence of actinide contraction the radius of the metal atom decreases as the 5f electrons of the actinides are poorly shielded. (Due to this poor shielding it is more strongly attracted by the nuclear charge resulting in decreased radius)
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.
Give an example of a metallic element and a nonmetallic element that ordinarily occurs as liquid?
An example of a metallic element that occurs as a liquid at room temperature is mercury. An example of a nonmetallic element that occurs as a liquid at room temperature is bromine.
What is the smallest part of a element that occurs naturally?
atom is the smallest part of element
What occurs to reducing agent in a reduction reaction?
An element is REDUCED. By that, it means that an element of a compound or an element in itself has gained electron/s when the reaction occurs. You can find this out when you see a change in their oxidation number.
Where does the element neon naturally occurs?
In the atmosphere.
Does copper occur naturally as an element or as a compound?
Copper occurs naturally as both an element and in various compounds. In its pure form, copper is an element on the periodic table with the symbol Cu. However, it can also be found in nature as compounds such as copper oxide and copper sulfide.
