3. A) Boron, element number 5, exists in only two common stable isotopes. They are B-10 and B-11. Given that the periodic table lists the average atomic mass as 10.81, which isotope must be more abundant? Why do you think so? (Prove it by doing some math). B) The average atomic mass of chlorine is 35.453. Does this mean that there are just two stable isotopes, one with atomic mass 35 and the one with atomic mass of 36? Explain your answer.

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.
Question
Transcribed Image Text:3. A) Boron, element number 5, exists in only two common stable isotopes. They are B-10
and B-11. Given that the periodic table lists the average atomic mass as 10.81, which
isotope must be more abundant? Why do you think so? (Prove it by doing some math).
B) The average atomic mass of chlorine is 35.453. Does this mean that there are just two
stable isotopes, one with atomic mass 35 and the one with atomic mass of 36? Explain
