I found in the tables of G. Audi, A. H. Wapstra and C. Thibault seven isotopes having a mass of approx. 264: 102No, 103Lr, 104Rf, 105Db, 106Sg, 107Bh, 108Hs.
Nobelium is credited with a standard atomic weight of [259]; but also Fm, Md, Rf, Db, Sg have isotopes with an Atomic Mass 259.
The atomic mass of magnesium is approximately 24.305 amu (atomic mass units).
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an elementβs isotopes based on their abundance in nature.
the element that has an atomic mass of 16.00 is sulfer.
Fluorine is a meta element. Atomic mass of it is 19.
gold is a meta element. Atomic mass of it is 197.
The mass number of thorium-234 is 234. This number represents the sum of the protons and neutrons in the nucleus of an atom of thorium-234.
The atomic mass of magnesium is approximately 24.305 amu (atomic mass units).
The element is Iodine (I). It has an atomic mass of about 126.9.
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an elementβs isotopes based on their abundance in nature.
the element that has an atomic mass of 16.00 is sulfer.
Fluorine is a meta element. Atomic mass of it is 19.
Gold is a meta element. Atomic mass of it is 197.
Iron is a meta element. Atomic mass of it is 56.
gold is a meta element. Atomic mass of it is 197.
The element with atomic mass 131 is Iodine (I)
