Over
100

Question 2

Learn how to rearrange Ar calculations here is an example.

Answer 2

X+Y= 100

Question 3

Give the principal energy levels and what sub levels are in them

Answer 3

Question 4

How many electrons do orbitals hold

Answer 4

2 electrons

Question 5

What is an atomic orbital

Answer 5

A region within an atom that can hold up to 2 electrons with opposite spins

Question 6

Order of increasing energy anomaly ?

Answer 6

4s comes before 3d

Question 7

What is the shape of a p orbital

Answer 7

Peanut shape (dumbbell shape)

Question 8

What id the shape of a S orbital

Answer 8

Sphere (circle )

Question 9

Give the sub level and the number of orbitals it has and how many electrons it can hold

Answer 9

Question 10

Which 2 atoms have an unexpected arrangement of electronic configuration and why

Answer 10

Cr and Cu
Both of them have only one electron in (4s1) as it’s a more stable arrangement
Which means 3d would have one extra electron

Question 11

When showing how electrons are arranged in subshells how are orbitals and electrons represented

Answer 11

Orbitals as boxes or lines
Electrons as arrows
