6 (a) An element X has an atomic number of 24 and a relative atomic mass of52.06. The natural element consists of four isotopes. The mass spectrum of the element X produced the following peaks of three of the isotopes on the chart recorder.Percentage83.804.302.4050 51 52 53 54 55 56 ...
The atomic weight (or mass number, A) is given as 52. The mass number is the sum of the number of protons and neutrons in the atom. We can use the formula: Mass Number (A)=Number of Protons (P)+Number of Neutrons (N) Plugging in the values we have: 52=24+N To find the num...

Aluminium (or aluminum in North American English) is a chemical element in the periodic table that has the symbol Al and atomic number 13. A silvery and ductile member of the poor metal group of elements, aluminium is found primarily as the ore bauxite and is remarkable for its resistance ...
(Fig.1c). The statistical average size and volume fraction is 0.65 nm and 4%, similar to those previously reported20. By using the atomic-scale geometric phase analysis (GPA) mapping24, strain fields are determined by reconstructing two lattice images of the fcc matrix and LCO regions ...
, it is impossible to only have one isotope especially if the element has more than one naturally-occurring isotope. As such, it is important to always consider that all the naturally-occurring isotopes are considered because, naturally, they will have an effect ...
However, designing materials with strong SOC in realistic materials has been quite straightforward because it simply links to the atomic mass of the constituent elements. Therefore, the candidates for spin-orbit active materials have mostly been limited to solids with heavy elements such as Bi, Sb,...
