QUESTION Bromine has two isotopes, 79Br and 81B.. To find out the isotopic abundance of each bromine isotope, a sample of Br, was injected to a mass spectrometer which subsequently released the spectra shown below. From each spectrum height was measured and tabulated. Using the data given, calculate the isotopic abundance of each bromine isotope. Using the isotopic abundances you will obtain, calculate the atomic mass of bromine.

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.
