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 molybdenum in these samples: mass relative isotope (amu) abundance 97, 'Mo 92, 96.91 Mo 91.91 94.6% 0 Mo Use these measurements to complete the entry for molybdenum in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. 5.4% Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for molybdenum in the Periodic Table we use here on Earth.

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.
