Answer:
a
Explanation:
ability to cause change in matter or the capacity to do work
b . transition metal
c . inner transition metal
d . lanthanides-series element
Answer:
A - actinide-series element
Explanation:
If you go to the periodic table, the atomic number is 92. if you look for 92 you will end up in the inner transition metals then if you get more detail it would be in the actinide section.
The most specific classification for the element uranium is option a, it is an actinide series element. It is a radioactive element.
Uranium is 92nd element in periodic table. This is a f- block element. In periodic table the elements of groups 3-12 is called transition metals. Elements in f block is called inner transition elements.
The inner transition elements contain two classification, lanthanides and actinides. 57th to 71th elements are called lanthanides. 89 to 103 are called actinides.
Thus, uranium belongs to the actinide series of f block elements in the periodic table therefore, option a is correct.
