RnHS Electron Configuration

Basics

100

What four letters represent the sublevels?

What is s, p, d, f

200

How many electrons can a p sublevel have?

6

300

What does a superscript represent in an electron configuration?

electrons

400

Which sublevel is represented by the transition metals?

d block

500

Why does the 3d sublevel follow the 4s sublevel?

3s and 3p hold 8 electrons, which is a full valence shell. A new energy level, represented by 4s, must begin before you can finish filling the 3rd energy level with 3d.
