2.5 Electrons and Bonding Flashcards
1
Q
Atomic orbitals
A
A volume of space which can hold a maximum of 2 electrons, if they are spin paired.
2
Q
Sub-Shell
A
A set of orbitals of the same type in the same energy level
3
Q
Energy level
A
All of the orbitals and sub-shells with the same “principal quantum number”
4
Q
s - orbital shape
A
spherical
5
Q

10
Q
Covalent bond - in terms of orbitals
A
The overlap of attomic orbitals each containing one electron.
11
Q
Dative covlent bond
A
a covalent bond in which the shaired pair of electrons has been supplied by one of the bonding atoms only.
