Elements that have been produced artificially through nuclear reactions have what atomic numbers?
Elements produced artificially through nuclear reactions can have atomic numbers ranging from 93 to 118. These elements are generally known as transuranium elements and are typically highly unstable isotopes with very short half-lives. Examples include elements like neptunium (atomic number 93) and einsteinium (atomic number 99).
What are the radioactive elements with atomic number from 90 to 103 in the periodic table called?
The elements with atomic numbers from 90 to 103 are called actinides. These elements are known for being radioactive and having partially filled 5f orbital. They include well-known elements like uranium, plutonium, and americium.
The two rows of elements placed at the bottom of the periodic table represent what elements?
The two rows of elements at the bottom of the periodic table are the lanthanides and actinides. The lanthanides are elements with atomic numbers 57 to 71, while the actinides are elements with atomic numbers 89 to 103. These rows are known as the f-block elements and are placed below the main body of the periodic table to conserve space.
What basic information is contained in the Periodic table of elements?
The periodic table include only chemical elements each has a unique atomic number that represents the number of protons in its nucleus. Most elements have differing numbers of neutrons among different atoms these are referred to as isotopes.
Why transuranic element known synthetic elements?
Transuranic elements are known as synthetic elements because they are not found naturally on Earth and must be created in a laboratory through nuclear reactions. These elements have atomic numbers higher than uranium (92) and are generally unstable and radioactive. Scientists have been able to produce transuranic elements by bombarding heavy elements with particles to create new elements.
Why are the elements 94 through 110 in the periodic table whole numbers?
1. All the atomic numbers are whole numbers. 2. If you think to atomic weight of heavy radioactive elements (atomic numbers from 93 to 118) is a rule of IUPAC to indicate in square parenthesis, [], the atomic mass of the most stable or known isotope.

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 are Lanthanides and Actinides?

The elements with atomic numbers of 58-71 not 5-71 are known as what on the Periodic Table?
lanthanides
What is the arragenment of all the known elements in order of their atomic numbers?
The arrangement of all known elements in order of their atomic numbers is called the periodic table of elements. The periodic table organizes elements based on increasing atomic number, showing similarities in properties and periodic trends across rows and columns.
What are the elements with atomic numbers from 58 to 71 called?
The elements with atomic numbers from 58 to 71 are called the lanthanides. They are a group of metallic elements that have similar chemical properties due to their electron configurations. The lanthanides are commonly used in various applications such as in the production of electronic devices and catalysts.
How are elements with atomic numbers higher than 92 created?
Isotopes were then explained as elements with the same number of protons, --- In the 1950s, the development of improved particle accelerators and --- All known isotopes of elements with atomic numbers greater than 82 are radioactive.Evaa_I_WILL_H3LP_YOU
Where are lanthanides located?
The lanthanide series comprises the fifteen metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. These fifteen elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. In the Group 3, Period 6 slot, After Barium and prior to Hafnium.
