To calculate the atomic mass of element R, we can use the following formula, which takes into account the masses and relative abundances of the isotopes: Atomic Mass=(m1×f1)+(m2×f2)+(m3×f3) Where: m1,m2,m3 are the masses of the isotopes, f1,f2,f3 are their respective...
For each atomic symbol, give the name of the element: a) Be b) Ag c) Si d) C Name the period I elements in the periodic table. Name an element in the fourth period (row) of the periodic table with four 4p electrons. For each of the following elements, use th...
aThe element X has three isotopes: X-221, X-220, and X-218, with masses 220.9, 220.0, and 218.1 amu. The relative abundances of these three isotopes are 74.22%, 12.78%, and 13.00%, respectively. Calculate the atomic mass of element X. 元素x有三同位素: X-221, X-220和X-218,与大量...
