Exploring the Bohr Model and Atomic Structure

The video tutorial explains how to draw and understand a Bohr model using nitrogen as an example. It covers the basics of atomic structure, including protons, neutrons, and electrons, and provides a step-by-step guide to drawing the Bohr model. The tutorial also discusses electron shells, valence electrons, and offers an alternative method for representing protons and neutrons in the diagram.

What is the first step in drawing a Bohr model?

• Drawing the nucleus

• Identifying the number of protons, neutrons, and electrons

• Adding electrons to the shells

• Calculating the atomic mass

How many protons does nitrogen have?

• 7

• 6

• 8

• 5

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

• Add the atomic number and atomic mass

• Subtract the atomic number from the atomic mass

• Divide the atomic mass by the atomic number

• Multiply the atomic number by the atomic mass

For a neutral atom, the number of protons is equal to the number of:

• Electrons

• Valence electrons

• Neutrons

• Atomic mass units

What do you place in the center of the Bohr model diagram?

• Protons and electrons

• Protons and neutrons

• Neutrons

• Electrons

How many electrons can the first shell of a Bohr model hold?

• 8

• 4

• 2

• 1

How many electrons does nitrogen have in its outer shell?

• 2

• 3

• 5

• 7
