Question

The 100th element is named in honour of:
A. Einstein
B. Bohr
C. Fermi
D. Curie

Answer 1

First we have to know that the 100th element is a man-made element, present in the F-block of periodic table and is named Fermium with symbol $Fm$.

Complete step by step answer:
Let’s start with discussing the 100th element of the periodic table. The 100th element is not a naturally found element, instead it’s an element which has been developed by scientists in a laboratory. This element was discovered/developed in the year 1952 in Lawrence Berkeley science laboratory and is named Fermium with the symbol Fm. These elements are present in the F-block of periodic table and as we know almost all elements of F-block are radioactive in nature; similarly this element is also radioactive in nature. The expected half-life of this element was measured 100.5 days which is relatively good.
Now coming back to the question, this element was named in the honour of Enrico Fermi. Enrico Fermi was one of the pioneers in nuclear sciences. So out of all the options given i.e. Einstein, Bohr, Fermi and Curie, the answer is Fermi.

So, the correct option to this question is option C. Fermi .

Note:
We must know that the Fermium was produced by the bombardment of actinides with neutrons inside the nuclear reactor. The fermium-257 is the heaviest isotope of this element. This element's first occurrence was in 1952 during a nuclear test where it was found in the debris of the nuclear bond. The element is radioactive with a half-life of 100.5 days.
