All of the actinides are radioactive, and almost all are synthetic.
Yes, Nobelium is a synthetic radioactive metal. It is part of the actinide series on the periodic table.
Db on the periodic table stands for Dubnium. It is a synthetic element with the atomic number 105 and is part of the actinide series. Dubnium is highly radioactive and is produced artificially in laboratory settings.
The actinide series of elements can be found in the f-block of the periodic table, specifically in the 7th row. These elements are known for their radioactive properties and include well-known elements such as uranium and plutonium.
The elements listed after plutonium on the periodic table are americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium. These elements belong to the actinide series and are synthetic, meaning they are not found in nature but are produced in laboratories through nuclear reactions.
Radioactive substances are not exclusive to the last period of elements on the periodic table, but many of the heaviest elements, particularly those in the actinide and transactinide series, are radioactive. These elements, found at the bottom of the periodic table, typically have unstable nuclei that decay over time. However, there are also radioactive isotopes of lighter elements scattered throughout the periodic table. Thus, while many radioactive elements are at the bottom, not all radioactive substances belong to this category.
Curium {Note correct spelling} is only element in the list given that is radioactive and synthetic.^ not correct answer and not even spelled right the correct answer is "lawrencium"The rare earth elements are located at the bottom of the periodic table and are comprised of the lanthanoid series and the actinoid series.The actinoid series is the second row of rare earth elements. All of these elements are radioactive, and all of these elements (except actinium, thorium, protactinium, and uranium) are synthetic.
The actinoids (formerly actinides) are all unstable metallic elements. The period 7 elements with atomic numbers from 89 (actinium, for which the group is named) through 103 comprise these elements. A link can be found below.

The Actinide series.
The Actinide series.
Actinide is not an element, but is a series of elements. Of the actinide series of elements, all except actinium, thorium, protactinium, and uranium are considered to be synthetic elements because they are not found in nature in appreciable amounts.
There are a total of 15 actinides in the actinide series and each are chemical elements with metallic properties. All of the actinide elements are radioactive and upon radioactive decay they release energy.
The element denoted by Rn 7s25f11 is Lawrencium (Lr), which has an atomic number of 103. It belongs to the actinide series of the periodic table. Lawrencium is a synthetic element and is highly radioactive.
Yes, Nobelium is a synthetic radioactive metal. It is part of the actinide series on the periodic table.
Actinide metals have unique properties including high density, high melting points, and the ability to exhibit multiple oxidation states. They are also radioactive and can undergo fission, making them important for nuclear power generation and weapons production. Additionally, actinides have a variety of magnetic and electronic properties that make them useful in various technological applications.
Db on the periodic table stands for Dubnium. It is a synthetic element with the atomic number 105 and is part of the actinide series. Dubnium is highly radioactive and is produced artificially in laboratory settings.
