Electron Structure

Question 1

What are the number of electrons that can fill the first four shells?

Answer 1

2, 8, 8, 18

Question 2

What are atomic orbitals?

Answer 2

Area of space containing 2 electrons (up, down (spin))

Question 3

What is the shape of an s-orbital?

Answer 3

spherical

Question 4

What is the shape of a p-orbital?

Answer 4

dumbell shape (there are 3 at right-angles to each other)

Question 5

What are the number of orbitals making up s-, p- and d-sub-shells?

Answer 5

1, 3 and 5 orbitals

Question 6

What are the number of electrons that can fill s-, p- and d-sub-shells?

Answer 6

2, 6 and 10 electrons

Question 7

How do you fill orbitals?

Answer 7

You fill the lowest energy levels first

Orbitals fill up singly before pairing up
