[Unit 1.3] | The Arrangement Of Electrons

Question 1

What did Schrödinger suggest in 1926?

Answer 1

Electrons have some properties of waves as well as particles.

Question 2

Who suggested that the inertness of noble gases was due to their full outer shells?

Answer 2

• Gilbert Lewis.
• His proposal also led to the belief that ions were formed due to the loss/gain of electrons to form full outer shells.

Question 3

What do later models of the atom suggest an electron is?

Answer 3

A smeared out cloud of charge, which meant you could never say exactly where an electron is.

Question 4

What formula can be used to determine the number of electrons held in each shell?

Answer 4

2n² (n1=2, n2= 8, n3= 18, n4 = 32)
