Atomic Structure and Properties

The video tutorial explains the atomic structure of neon, focusing on its atomic number, mass number, and electron configuration. It details how to calculate the number of protons, neutrons, and electrons, and how these particles are arranged in shells around the nucleus. The tutorial emphasizes the stability of noble gases like neon, which do not typically form bonds due to their full electron shells.

What is the atomic number of neon?

• 14

• 8

• 10

• 12

Why is the mass number of neon approximated to 20?

• Because it is a prime number

• To simplify calculations

• To match the atomic number

• Due to rounding errors

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

• Divide the mass number by the atomic number

• Add the atomic number to the mass number

• Subtract the atomic number from the mass number

• Multiply the atomic number by the mass number

What is the charge of a neutron?

• Variable

• Negative

• Positive

• Neutral

How many electrons can the first shell of an atom hold?

• 2

• 8

• 4

• 6

What is the maximum number of electrons the second shell can accommodate?

• 2

• 4

• 6

• 8

Why do noble gases like neon generally not form bonds?

• They have a full outer shell

• They are unstable

• They have an odd number of electrons

• They are too heavy

What happens to electron shell configuration after calcium?

• It is not defined

• It becomes more complex

• It remains the same

• It becomes simpler

How many protons does neon have?

• 10

• 8

• 12

• 14

What is the total atomic mass of neon when protons and neutrons are added?

• 40

• 20

• 10

• 30
