What else can I help you with?
Are actinoids all transuranium elements?
No, actinoids are a group of elements that include both transuranium elements (elements with atomic number greater than 92) and non-transuranium elements. Transuranium elements are specifically those that have atomic numbers higher than uranium (92).
Are transuranium elements found in small quantities in remote planets?
yes
What is Einsteinium's natural state?
Einsteinium is a radioactive synthetic element that is not found naturally on Earth. It is typically produced in nuclear reactions involving uranium and transuranium elements.
How many places on the periodic table are the elements not in order by increasing atomic mass?
Classical pairs ate tellurium-iodine, thorium-protactinium, uranium-neptunium; and also some transuranium elements.
Why did Edwin Mattison McMillan win The Nobel Prize in Chemistry in 1951?
The Nobel Prize in Chemistry 1951 was awarded jointly to Edwin Mattison McMillan and Glenn Theodore Seaborg for their discoveries in the chemistry of the transuranium elements
Are actinoids all transuranium elements?

Named for the university where many of the transuranium elements were synthesized?

Which is not a property of the transuranium element?
Transuranium elements are synthetic and do not occur naturally in significant quantities.
Which equation represents the synthesis of a transuranium element?
A possible equation for the synthesis of a transuranium element could be: Plutonium-239 + Neutron → Curium-240. This process involves bombarding a transuranium element like plutonium with an extra neutron to create a heavier transuranium element like curium.
Which element has the lowest atomic number transuranium?
The element with the lowest atomic number among the transuranium elements is neptunium, with an atomic number of 93. It is the first transuranium element produced synthetically in a laboratory setting.
How an elements is classified as transuranium elements?
Elements having more than 92 protons, the atomic number of uranium, are called transuranium elements.
What is the first transuranium element?
The first transuranium element is neptunium (Np), with atomic number 93. It was first synthesized in 1940 by Edwin McMillan and Philip H. Abelson at the University of California, Berkeley.
How is an element classiffied as a transuranium element?
An element is classified as a transuranium element if its atomic number is greater than 92, which is the atomic number of uranium. These elements are all synthetic and are typically produced in laboratories through nuclear reactions. They are highly unstable and have very short half-lives.
How do transuranium metals differ from inner transition metals?
Yes
What is the first trans uranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
Is actinoids all transuranium elements?
no. uranium and thorium occur in nature
What elements are synthesized in a laboratory by using nuclear accelerators?
Transuranium metals
