Drawing Bohr-Rutherford Diagrams for Phosphorous

This video tutorial explains how to draw Bohr-Rutherford diagrams, using phosphorus as an example. It covers determining the number of protons and neutrons based on atomic number and weight, and placing electrons in shells according to the Bohr model. The tutorial emphasizes the importance of understanding electron configuration and provides tips for drawing diagrams for elements up to atomic number 20.

What is the first step in drawing a Bohr-Rutherford diagram?

• Determine the number of electrons

• Determine the number of protons and neutrons

• Draw the electron shells

• Calculate the atomic weight

How do you find the number of protons in an atom?

• By adding the number of neutrons and electrons

• By looking at the atomic number

• By subtracting the number of neutrons from the atomic weight

• By looking at the atomic weight

What is the atomic number of phosphorus?

• 20

• 15

• 31

• 16

How do you calculate the number of neutrons in an atom?

• Add the atomic number to the atomic weight

• Divide the atomic weight by the atomic number

• Subtract the atomic number from the atomic weight

• Multiply the atomic number by the atomic weight

What represents the nucleus in a Bohr-Rutherford diagram?

• A triangle

• A square

• A small circle with protons and neutrons inside

• A large circle

How many electrons can the first electron shell hold?

• 10

• 8

• 2

• 16

How many electrons can the second electron shell hold?

• 10

• 16

• 5

What should you do if you need to draw a Bohr-Rutherford diagram for elements beyond atomic number 20?

• Ignore the additional electrons

• Refer to a specialized video or resource

• Use the same method as for elements below 20

• Draw only the first two shells

What is the maximum number of electrons that can fit in the fourth shell?

• 2

• 8

• 18

• 32
