What are two synthetic elements with atomic numbers less than 92?
Technetium, Tc, and promethium, Pm
Synthetic elements are found in what group?
Synthetic elements are found in the group of transuranium elements, which are elements with atomic numbers higher than uranium (92) on the periodic table. These elements are artificially created in a laboratory through nuclear reactions and have unstable nuclei.
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.
How many transurnic elements are discovered so far?
There are 26 transuranic elements that have been discovered so far. These elements have atomic numbers greater than uranium (92) and are all synthetic, meaning they do not occur naturally on Earth.
What are the elements in a synthetic diamond?
Carbon

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.

Do all synthetic elements have more than 92 elements?
All the synthetic elements on the Periodic Table appear after Uranium (atomic no. 92). These are the only synthetic elements.
What are elements that are made in lab called?
Elements that are made in a laboratory are typically referred to as synthetic elements. These elements are not found naturally on Earth and are produced by scientists through various experimental methods. Examples of synthetic elements include einsteinium and seaborgium.
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.
Synthetic elements are formed by experimentation?
Yes, all synthetic elements are man made.
What are super heavy elements?
Super heavy elements are elements with atomic numbers greater than 104. They are synthetic and do not occur naturally on Earth. These elements are typically produced in laboratories through nuclear reactions involving heavy 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.
How many transurnic elements are discovered so far?
There are 26 transuranic elements that have been discovered so far. These elements have atomic numbers greater than uranium (92) and are all synthetic, meaning they do not occur naturally on Earth.
What are elements called that are created by main in a laboratory?
Synthetic or man-made elements. Obviously synthetic sounds significantly cooler.
What are elements that can not be found on earth and can be created called?
The forgotten natural rubber that once powered the world, from a tree called balata, which is found in British Guiana, now called ( Guyana) in the north of South America. It is one of the most incredible element, that has been replaced be synthetic rubber and is very polluting for our beautiful planet, because it is petroleum based. The Word of God, the Bible has a lot of wisdom lessons to teach, which we have neglected, and have had detrimentale effects on our world, to this day. The Book of Jeremiah 10: 23 in the Bible explains in simple words that " It does not belong to man who is walking, even to direct his step. History has shown what a poor job we have done so far. Humans are more focussed on their smartphones today, than being focussed on what God's creation could teach us in terms of wisdom. The Book of Proverbs 6: 6-8 in the Bible tells us to go to the ant, observe its ways and become wise. Ants are remarkably cooperative, they keep their environment very clean and show concern for their fellows, at time assisting injured or exhausted ants back to the nest. The Book of 2 Timothy 3: 1-5 describe the way humans behave today, in these words. " People are lovers of themselves, lovers of money, having no natural affection, lovers of pleasure rather than lovers of God, who is the Creator of our beautiful planet. Read Revelation 4: 11 So to answer your question, which is " What are the elements that cannot be found on earth and can be created. The answer is: Human technology have only been able to imitate a pale copy of some elements found on earth, with detrimental effects.
