Terms in this set (14)
What is a shell?
A group of atomic orbitals with the same principle quantum number, n
What is an atomic orbital?
A region around the nucleus that can hold up to two electrons, with opposite spins
How many electrons can a shell hold?
What shape is an s orbital?
How many electrons are in an s orbital?
All shells contain an s orbital, that hold up to two electrons
What shape is a p orbital?
3D dumb bell shape
How many electrons are in a p orbital?
From the second shell, each p orbital has three orbitals at right angles to each other, that each contain up to two electrons
How many electrons in a d orbital?
From the third shell, each shell has five orbitals, that each contain up to two electrons
What is the fill order of electrons?
What order do electrons fill up shells in?
In order of increasing energy
What is an ionic bonding?
The electrostatic attraction between oppositely charged ions
What is a giant ionic lattice?
Where the attraction between oppositely charged ions is spread throughout an ionic substance
Do giant ionic lattices have a high or low melting and boiling point?
A high melting and boiling point
Why do giant ionic lattices have a high melting and boiling point?
Lots of energy is needed to overcome the strong electrostatic attraction between ions throughout the structure
