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 explain…

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.

Textbook Question

Chapter 2, Problem 121QP

Some tables list relative atomic mass to as many signiï¬�cant ï¬�gures as can be reported accurately. The relative atomic mass of argon, 39,948 amu, is known to ï¬�ve signiï¬�cant ï¬�gures, while that of ï¬‚uorine, 18,9984032 amu, is known to nine significant ï¬�gures. Natural samples of argon contain three isotopes, but natural samples of ï¬‚uorine contain only one. Explain why their relative atomic masses differ in the number of signiï¬�cant ï¬�gures reported.
