What specific name is given to elements with atom numbers 90 to 103?
Elements with atomic numbers 90 to 103 are known as actinides.
What elements are synthetic elements?
Sythetic elements are those with half lifes to small to be found in nature, they are manmade and generally fairly unstable. The synthetic elements are: All elements with atomic numbers 1 through 98 are naturally occurring at least in trace quantities, but the following elements are usually produced through synthesis. Except for francium, they were all discovered through synthesis before being found in nature.Element nameChemical SymbolAtomic NumberFirst definite discoveryTechnetiumTc431936PromethiumPm611945AstatineAt851940FranciumFr871939NeptuniumNp931940PlutoniumPu941940AmericiumAm951944CuriumCm961944BerkeliumBk971949CaliforniumCf981950 The following elements do not occur naturally on Earth.

What are some elements that do not have a permanent name yet?
In the field of chemistry, elements with atomic numbers higher than 104 are known as transuranium elements and most of them do not have permanent names yet. These elements are typically synthesized in laboratories and are highly unstable, making it challenging to study and name them definitively. Instead, they are often assigned temporary systematic names based on their atomic numbers until further research can confirm their properties and characteristics.
What is the name of any element of the actinide series which have atomic numbers from 89 actinium Ac through 103 lawerencium Lr?
One element in the actinide series is thorium (Th), which has an atomic number of 90.
What is the Name of scientist who sorted the elements into order?
In 1913, almost fifty years after Mendeleev, Henry Moseley published the results of his measurements of the wavelengths of the X-ray spectral lines of a number of elements which showed that the ordering of the wavelengths of the X-ray emissions of the elements coincided with the ordering of the elements by atomic number. With the discovery of isotopes of the elements, it became apparent that atomic weight was not the significant player in the periodic law as Mendeleev, Meyers and others had proposed, but rather, the properties of the elements varied periodically with atomic number. When atoms were arranged according to increasing atomic number, the few problems with Mendeleev's periodic table had disappeared. Because of Moseley's work, the modern periodic table is based on the atomic numbers of the elements.
What specific name is given to elements with atomic numbers 90 to 103?
Actidines.
What specific name is given to elements with atom numbers 90 to 103?
Elements with atomic numbers 90 to 103 are known as actinides.
What is oxide atomic number?
The atomic number of oxide depends on the specific element it is composed of. For example, the atomic number of oxygen, which commonly forms oxides, is 8. Other elements forming oxides will have their own unique atomic numbers.
What are the 4 things that the elements in the p-block contains?
It contains the symbols, atomic number, atomic name and the real name of the elements.
What is the name of a table that shows the element arranged by their atomic numbers?
That table or chart would be the "Periodic Table" commonly found in any good chemistry text book.
What is an element that has the same atomic number but different mass numbers?
Isotopes are elements that have the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. For example, Carbon-12 and Carbon-14 are isotopes of carbon.
What is another name for atomic numbers?
Proton number
What does elements symbol consist of?
A periodic table is a chart with all of the elements and their symbols, their atomic numbers and atomic masses. Good ones will also have the name of the element to make finding them easier.
