Electron Configuration I

Watch the following video and answer the questions that follow.

1

According to the Bhor's model, electrons

Are mixed with the neutrons

Orbit around the nucleus

Are very close to the nucleus

Are inside the nucleus

1

According to the Bhor's model, removing electrons from an atom

Requires energy

Can never happen

Happens on its own

Releases energy

1

What do we call the circles where the electrons orbit the atom?

They are undefined

Orbiting Circles

Obitals

Energy Levels

1

Removing an electron to further outer shell requires more energy. What is the reason for this?

The statement is false.

It does not take energy to revove an electron because electrons are also positive.

It takes more energy to remove the electron further away from the nuclues.

It takes more energy to remove the electron further away from the nucleus becasue the electrons become more negative as they move away.

1

How do we label energy levels?

Using numbers, 0, 1, 2, 3 ...

Using numbers, 1, 2, 3...

Using the alphabet

We don't have a way to label energy levels.

1

When an electron is found in the following energy level is closest to the nucleus?

n = 0

n = 3

n = 5

n = 1

1

When an electron is found in the following energy level, it is further from the nucleus?

n = 3

n = 5

n = 6

n = 1

1

Select all true staments.

1

Which of the following are classifed as energy sub-levels?

1

Select all correct elements

n = 1 has the following sub-leves: s, p d

The energy level (n ) determines the number of sub-levels in that energy level.

n = 1 has the following sub-leves: s only

n = 3 has the following sub-leves: s, p d

n = 4 has the following sub-leves: s, p, d and f

n = 2 has the following sub-leves: s and p

n = 2 has the following sub-leves: s, p d

1

Each sub-level has obritals (regions of space). Select all that apply.

1

Each orbital can occupy a maximum of _____ electrons

1

3

2

4

1

Electrons in a orbital must ________ according to Pauli's Exclusion Principal.

Spin in opposite directions

Rotate around the nucleus

Spin in the same direction

Remain the same

1

What do we use to represent electron spin?

Dots

NO representation

Arrow pointing up or down

A lovely heart!
