Is it true that transuranium elements are synthetic elements with atomic numbers greater than 92?

Yes. All elements classified after Element Atomic Number 92 (Uranium) (id est transuranium) are synthesised elements and can not be found naturally. They are also all radioactive, although this is the case for elements from elements 84 onwards.

Why are elements with atomic numbers higher than 92 referred to as transuranium elements?
the atomic number of uranium is 92. the elements after that is thus called trans-uranium (meaning after uranium)
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 does elements with a higher atomic number than uranium have?
More electrons, protons, neutrons and a greater atomic weight.
Chemical elements with atomic numbers greater than that of uranium are called?
Transuranic elements
What are elements that are made in lab called?
Synthetic is the term you are looking for i believe.
What are elements with atomic numbers above 95 called?
These elements (neptunium and heavier) are called transuranic elements or trans-uranium elements. They could also properly be called artificial and radioactive.*Both plutonium and neptunium, first known through synthesis, have been found to occur naturally in trace amounts, along with americium, curium, berkelium and californium. These occur through a natural version of the synthesis process, within quantities of uranium ore.
Any element with an atomic number greater than 92 is?
All elements with atomic numbers greater than 83 are radioactive. All the nuclei of these elements are blown apart because of their enormous positive charges.
Why are elements with atomic numbers higher than 92 referred to as transuranium elements?
the atomic number of uranium is 92. the elements after that is thus called trans-uranium (meaning after uranium)

More electrons, protons, neutrons and a greater atomic weight.
Chemical elements with atomic numbers greater than that of uranium are called?
Transuranic elements
What are two synthetic elements with atomic numbers less than 92?
Technetium, Tc, and promethium, Pm
Does europium occur naturally or is it synthetic?
It is natural. All elements with atomic numbers 92 and lower are naturally occurring.
What are elements that are made in lab called?
Synthetic is the term you are looking for i believe.
What are transuranium elements?
Elements in the periodic table with the atomoc numbers above 92, such as: Neptunium(93), Plutonium(94), Americium(95), Curium(96), Berkllum(97), Californium(98), Einsteinium(99), Fermium(100), Mendelevium(101), Nobellim(102), Lawrencium(103), Rutherfordium(104), Dubnium(105), Seaborgium(106), Bohrium(107), Hassium(108), and Meitnerium(109)
What are transuranics?
transuranic elements are all elements with atomic numbers greater than 92, uranium is 92 so transuranic is past uranium
How do transuranium elements differ from other inner transition metals?
Transition metals are d-block elements. Their general electronic configuration is (n-1)d1-9 ns0-2. The last electron enters the d-subshell.Inner Transition metals are f-block elements. Their general electronic configuration is (n-2)f1-13(n-1)d1-9 ns0-2. The last electron enters the f-subshell.
