Question 5

2015-09-29 06:17:29 UTC

Magnesium (12)

2015-09-29 06:24:34 UTC

3s orbital is the last orbital to be filled with 2 electrons which shows that Mg is in Group 2.

Special Case Chromium & Copper

2015-09-29 06:29:17 UTC

Chromium - 3d orbitals is 5 and 4s orbitals is 1 this is because half filled orbitals are more stable than partially filled orbitals.

Copper - 3d orbitals is 10 and 4s orbitals is 1 this is because half filled orbitals are more stable than partially filled orbitals.

Question 6

2015-09-29 06:35:59 UTC

Sodium & Chloride ions

2015-09-29 06:37:21 UTC

Positive ions are formed by removing electron and negative ions are formed by adding electron.

Pauli's Exclusion Principle

Aufbau principle

2015-09-29 06:44:30 UTC

o Electrons must occupy available orbitals of lower energy before they fill orbitals of higher energy

o Building up concept

P orbital

2015-09-29 06:45:37 UTC

start to appear on 2nd shell / n=2 / energy level 2. 3 types : Px, Py, Pz. Can hold maximum 6 electrons.

Iron to Iron II)

2015-09-29 06:46:59 UTC

Iron is 1s2 2s2 2p6 3s2 3p6 3d6 4s2

in Iron ion it becomes 1s2 2s2 2p6 3s2 3p6 3d6 since 2 electrons have been removed.

H

2015-09-29 06:47:11 UTC

D orbital

2015-09-29 06:50:35 UTC

- start to appear on the third shell/ n=3/ energy level 3. 5 types. Maximum 10 electrons.

S orbital

2015-10-06 05:40:51 UTC

S orbital is the closest orbital to the nucleus, with other orbitals lining up further away. According to Pauli exclusion principle, the maximum is s2, where 2 represents the number of equivalent electrons
