Electronic Structure Flashcards
1
Q
What are electrons arranged in?
A
Energy levels
2
Q
What is an orbital
A
The shape of the path an electron takes around the nucleus
3
Q
How many electrons can an orbital hold?
A
Two
4
Q
What shape is an s orbital
A
Spherical
5
Q
What shape is a P orbital
A
Figure of eight
6
Q
Which type of orbital comes after 4s and why
A
3D because they have slightly more energy
7
Q
Which are the exceptional elements in the transition metals in period four
A
Copper and chromium
8
Q
Why are copper and chromium exceptional
A
They have 4 and 9 electrons in their outer shells respectively and so a 4s electron joins the 3d orbital to create a half full/full outer shell
9
Q
What is an isoelectronic ion
A
Ions with the same electronic figuration as an atom
