Electron Shell

What do electrons have?

Fixed energies

What are shells or energy levels?

Electrons move around the nucleus in certain regions of the atom

What's each shell given?

A number, the principal quantum number

When a shell is further from the nucleus, what does this mean?

The higher its energy and the larger its principal quantum number

What are shells divided up into?

Sub-shells

What do different electron shells have?

Different numbers of sub-shells, which have a different energy

What are the 4 types of sub-shells?

S sub-shell, p sub-shell, D sub-shell and F sub-shell

What do sub-shells have?

Different numbers of orbitals which can each hold up to 2 elections

How many orbitals can the s sub-shell have and what's the maximum electrons?

1 orbital and 2 electrons

How many orbitals can the P sub-shell have and what's the maximum electrons?

3 orbitals and 6 electrons

How many orbitals can the d sub-shell have and what's the maximum electrons?

5 orbitals and 10 electrons

How many orbitals can the f sub-shell have and what's the maximum electrons?

7 orbitals and 14 electrons

What are the sub-shells in the 1st shell and what are the total number of electrons?

1s and 2 electrons

What are the sub-shells in the 2nd shell and what are the total number of electrons?

2s and 2p and 8 electrons

What are the sub-shells in the 3rd shell and what are the total number of electrons?

3s, 3p and 3d and 18 electrons

What are the sub-shells in the 4th shell and what are the total number of electrons?

4s, 4p, 4d, 4f and 32 electrons
