These are quite significant in the discoverings of new elements; they are known widely as the "post-uranium" elements. i.e. the elements discovered after uranium, which is the main component in nuclear bombs.

Why atomic mass is always greater than atomic number?
Atomic number indicates the number of protons in the nucleus of a given element, whereas atomic mass results from protons and neutrons.
How are mass number and atomic number of an element related?
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
What element is in group 1 and has a higher atomic number than chlorine but a lower atomic number than chlorine?
It is K, or Potassium, which atomic number is 19, which is greater than 17 and less than 35, and in group 1 of the periodic table, which is the alkali metals.
3 element with atomic number greater than 92?
#93 Neptunium See also the periodic table at the link below.
Why is the atomic number included in the periodic table?
Presumably because atomic number is the fundamental characteristic for organizing the periodic table itself. Every element in the interior of a period of the periodic table has an atomic number greater by 1 than its neighbor to the left and less by 1 than its neighbor to the right; every element (except hydrogen) at the left end of a periodic table period has an atomic number greater by one than the rightmost member of the preceding period; and every element at the right end of a periodic table periodic has an atomic number less by 1 than the leftmost element in the succeeding period, if such a succeeding period exists.
What element has an atomic number greater than 32?
Gold is one.
What element has an atomic number that is six times greater than element beryllium?
The atomic number of beryllium is 4. The required element should have the atomic number 4x6=24. The corresponding element is Vanadium (V).Atomic number of Beryllium is 4. Six times of it is 24. Chromium has an atomic number of 24.
Why are Elements whose atomic numbers are greater than 92 are sometimes referred to as the transmutation elements?
Because no element with an atomic number greater than 92 occurs naturally; any such element is made by transmutation of another element.
What element has a gram atomic mass that is greater than the gram atomic mass of the element with an atomic number higher by one unit?
Both argon and cobalt have this characteristic.
Which element is thousands time greater than uranium?
It is not clear what "greater" means. In terms of atomic number (number of protons in the nucleus) there is not even an element which is twice as great.
Why atomic mass is always greater than atomic number?
Atomic number indicates the number of protons in the nucleus of a given element, whereas atomic mass results from protons and neutrons.
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.
What does elements with a higher atomic number than uranium have?
More electrons, protons, neutrons and a greater atomic weight.
What is the first transuranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
What is the first trans uranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
How are mass number and atomic number of an element related?
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
What element has an atomic mass greater than 75 but less than 79?
Element 34, Selenium, has an atomic mass of about 78.96.
