What is the Valency of rutherfordium?
The oxidation state +4 is the only stable state for the latter two elements and therefore rutherfordium should also exhibit a stable +4 state. In addition, rutherfordium is also expected to be able to form a less stable +3 state.

How do you make rutherfordium?
Rutherfordium can be made by bombarding plutonium-242 with accelerated neon ions or by bombarding californium-249 with accelerated carbon ions. Isotopes: Rutherfordium has 15 isotopes whose half-lives are known, with mass numbers from 253 to 268. None are stable.
In what group of periodic table is rutherfordium?
Group IVb
rutherfordium (Rf), an artificially produced radioactive transuranium element in Group IVb of the periodic table, atomic number 104. Soviet scientists at the Joint Institute for Nuclear Research at Dubna, Russia, U.S.S.R.
What is rutherfordium classified?
transition metal
Rutherfordium is a chemical element with symbol Rf and atomic number 104. Classified as a transition metal, Rutherfordium is a solid at room temperature.
How many protons and neutrons does rutherfordium have?
How many isotopes does rutherfordium have?
15 isotopes
Rutherfordium has 15 isotopes with mass numbers ranging from 253Rf to 268Rf. None of them are stable and occur in nature. Rf is the longest-lived isotope with a half-life of 1.3 hours.
What group is rutherfordium in the periodic table?
How many electrons are there in a neutral atom of rutherfordium?
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Rutherfordium is 104. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom.
What is the half life of rutherfordium?
Rutherfordium is element #104 and is a man-made element, meaning it is not found in nature. This is due to it’s relatively short half-life. As a trans-uranium element (all those that come after the element Uranium) it’s radioactive. The most stable isotope is Rf 267, with a half-life of just over an hour.
Where are valence electrons found in an element?
For main group elements (i.e s-block and p-block elements), the valence electrons are the electrons present in the outermost orbit. But for most of the transition and inner transition elements, the valence electrons are the electrons present in the shells outside the noble gas core.
