Bohr-Rutherford Diagrams and Electron Shells

The video tutorial explains how to draw Bohr diagrams for elements beyond atomic number 20, focusing on germanium. It covers the complexity of electron configurations and the order of filling electron orbitals. The tutorial uses a chart to guide the placement of electrons in different shells, emphasizing the importance of following the correct order for elements with more than 20 electrons. The process is demonstrated step-by-step, culminating in a complete Bohr diagram for germanium with 32 electrons, 32 protons, and 41 neutrons.

Why is it uncommon to draw Bohr-Rutherford diagrams for elements beyond calcium?

• They do not exist in nature.

• They are not stable.

• They are too simple.

• They become complex as you move through the periodic table.

What is the first step in creating a Bohr-Rutherford diagram for germanium?

• Calculate the atomic mass.

• Draw the electron shells.

• Identify the number of protons and neutrons.

• Determine the number of electrons.

In the Bohr-Rutherford diagram, what does the 'S' in the electron orbital chart represent?

• The shape of the orbital.

• The stability of the element.

• The speed of electrons.

• The size of the atom.

How many electrons can the first shell hold in a Bohr-Rutherford diagram?

• Eight

• Six

• Two

• Four

What is the maximum number of electrons that can be placed in the third shell before returning to the fourth shell?

• Ten

• Eight

• Fourteen

• Twelve

Why do you return to the third shell after starting to fill the fourth shell?

• To reduce energy levels.

• To increase stability.

• To follow the order of filling.

• To balance the atom.

How many electrons are in the fourth shell of germanium's Bohr-Rutherford diagram?

• Eight

• Four

• Six

• Two

What is the total number of electrons in germanium's Bohr-Rutherford diagram?

• 30

• 32

• 28

• 34

What is the key challenge when drawing diagrams for elements with atomic numbers greater than 20?

• Following the correct order of electron filling.

• Finding the correct atomic mass.

• Identifying the element's position in the periodic table.

• Determining the number of protons.

What is the significance of the order of filling electron orbitals?

• It influences the element's atomic mass.

• It affects the element's chemical properties.

• It ensures the atom's stability.

• It determines the element's color.
