Question 1: The sample contained the three isotopes 24Mg, 25Mg and 26Mg. The percent abundance of the isotopes and the mass are as follows 78.09% of 24Mg, 10.00% of 25Mg, and 11.01% of 26Mg. Calculate the relative atomic mass (A,) of magnesium, accurate to two decimal places. Three Isotopes: ^24Mg, ^25Mg, and ^26Mg. Stated Percent abundance: Question 2: Naturally occurring chlorine is 75.78% 35Cl which has an atomic mass of 34.969amu and 24.22%. 37Cl, which has an atomic mass of 36.966amu. Calculate the average atomic mass.

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.
