Understanding Atomic Structure and APE-MAN Strategy

The video tutorial explains the APE-MAN strategy for determining the number of sub-atomic particles in neutral atoms. It covers how the atomic number equals the number of protons and electrons, and how the mass number minus the atomic number gives the number of neutrons. Examples with sulfur, sodium, and carbon illustrate the process of finding atomic numbers, mass numbers, and calculating neutrons.

What does the 'A' in the APE-MAN strategy stand for?

• Atomic number

• Atomic mass

• Atomic weight

• Atomic structure

In the APE-MAN strategy, what is equal to the number of protons?

• Neutrons

• Electrons

• Atomic mass

• Atomic weight

For sulfur, what is the atomic number?

• 15

• 14

• 16

• 17

How do you calculate the number of neutrons using the APE-MAN strategy?

• Divide atomic number by mass number

• Subtract atomic number from mass number

• Add atomic number to mass number

• Multiply atomic number by mass number

What is the mass number of sulfur when rounded?

• 30

• 31

• 33

• 12

• 11

• 10

What is the rounded mass number for sodium?

• 22

• 24

• 23

• 21

How many neutrons are in sodium according to the APE-MAN strategy?

• 10

• 11

• 12
