Watch the following video and answer the questions that follow. 

Question 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 

Question 2

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

Requires energy 

Can never happen 

Happens on its own 

Releases energy 

Question 3

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

They are undefined

Orbiting Circles 

Obitals 

Energy Levels 

Question 4

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. 

Question 5

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. 

Question 6

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

n = 0

n = 3 

n = 5 

n = 1 

Question 7

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

n = 3 

n = 5 

n = 6

n = 1 

Question 8

Select all true staments.

n = 3 can hold 18 electrons

n = 3 can hold 8 electrons

n = 1 can hold 2 electrons

n = 1 can hold 3 electrons

n = 2 can hold 18 electrons

n = 2 can hold 8 electrons

Question 9

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

h

p

k

f

d

s

Question 10

10.

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

Question 11

11.

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

d sub-level has 6 obitals

p sub-level has 3 obitals

s sub-level has 1 obitals

p sub-level has 2 obitals

s sub-level has 2 obitals

d sub-level has 5  obitals

Rotate around the nucleus 

Spin in the same direction 

Remain the same 

Question 14

14.

What do we use to represent electron spin?

Dots 

NO representation 

Arrow pointing up or down 

A lovely heart!
