. Explain the role of relative weight in determining the atomic mass of an element. 2. Differentiate between atomic number and mass number. Why is atomic number listed on the periodic table but mass number is not? 3. An element has five isotopes. Calculate the atomic mass of this element using the information below. Show all your work. Using the periodic table, identify the element this is likely to be and explain your choice. Isotope 1 – mass: 64 amu; percent abundance: 48.89% Isotope 2 – mass: 66 amu; percent abundance: 27.81% Isotope 3 – mass: 67
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.
