Experiments show that each element in the periodic table has a unique set of spectral lines. What is the best explanation for this observation?

Each atom has a unique nucleus.

The number of electrons within each atom is unique.

Each element has a unique set of interactions between its electrons and its protons.

The motion of the electrons within each atom is unique.

Each atom has a unique set of energy levels.

Solutions

Expert Solution

The best explanation to the question is that each atom has a unique set of energy levels. This is because spectral lines originate due to the transition of electron from one energy level to other and as each atom has unique set of energy levels therefore each set has a unique set of spectral lines.

Each element has a unique atomic number, which is listed on the periodic table above the chemical symbol for the element. The atomic number is equal to the charge on the nucleus. The atomic number also equals the number of protons in the nucleus and the number of electrons in the neutral atom of the element. For example, Fluorine (F) has the atomic number 9, which means that its atoms contain 9 protons and 9 electrons. Zinc (Zn) has the...
