Finding atomic mass from isotope mass and natural abundance A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of tin in these samples: isotope mass relative (amu) abundance 118.9 93.3% 11⁹ Sn 118, Sn 117.9 0 Sn 6.7% Use these measurements to complete the entry for tin in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for tin in the Periodic Table we use here on Earth. S
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.


Tin (Sn) is a chemical element found on the periodic table with the atomic number 50 and the symbol Sn.
To calculate the atomic mass of an element, you need to consider the contributions from each of its isotopes, weighted by their relative abundances. In this case, we have two isotopes of tin (Sn):
Isotope: 119Sn Mass: 118.9 amu Relative Abundance: 93.3%
Isotope: 118Sn Mass: 117.9 amu Relative Abundance: 6.7%
