Question

What is the IUPAC symbol of Rutherfordium?
A.Rt
B.Ru
C.Rf
D.Rd

Answer 1

Hint:Rutherfordium is an element present in periodic table with atomic number 104.it is named after physicist Ernest Rutherford. Its IUPAC symbol is Rf. It is highly radioactive in nature. Around nine isotopes of this element are known.

Complete step by step answer:
Rutherfordium is a radioactive element with atomic number 104 i.e. it contains 104 protons in it. IUPAC stands for International Union of Pure and Applied Chemistry. The IUPAC symbol for Rutherfordium is ‘Rf’. Its melting point is 2400K and atomic mass is 267u. It is highly radioactive i.e. it spontaneously emits radiation in the form of particles. Out of its nine isotopes, the most stable one has half life time of just about 13 hours. Its location in the periodic table is under group-4, period-7 and block-d. Rutherfordium is categorized under transition metals. It is named after Father of Nuclear Physics, Ernest Rutherford who was from New-Zealand.

So, the correct option is (C).

Note:
This element is dangerous for health as it is radioactive so it emits ionizing radiations. These radiations have quite high penetrating power with which they can even penetrate skin and bones causing various severe health hazards and even death on large exposures to radiation.
Note: Rutherfordium is a synthetic element which means it is not found on earth naturally but created in laboratories. It has been created in small amounts only. It decays through the process of spontaneous fission. It was discovered in 1964. It doesn’t have many uses but due to its highly radioactive nature it is used in nuclear reactions.
