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.
Only one element can have any specified atomic number. For 83, the element is bismuth.
Elements that have atomic numbers than 84 are radioactive.

Transuranium.
Because no element with an atomic number greater than 92 occurs naturally; any such element is made by transmutation of another element.
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.
Chromium (Cr), which has an atmoic number of 24. Beryllium has an atomic number of 4, so 4*6=24, which is Chromium.
Examination of a periodic table shows that the element is potassium.
It could be potassium(K)
Gold is one.
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.
Because no element with an atomic number greater than 92 occurs naturally; any such element is made by transmutation of another element.
Both argon and cobalt have this characteristic.
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.
Atomic number indicates the number of protons in the nucleus of a given element, whereas atomic mass results from protons and neutrons.
More electrons, protons, neutrons and a greater atomic weight.
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.
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.
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
Element 34, Selenium, has an atomic mass of about 78.96.
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.
