2.2.1 + 2.2.2 Electrons Bonding And Structure (Dr C) Flashcards
What is the first sub shell
S-orbital
How many electrons can the s orbital hold
2
How many s orbitals are there in each shell
1
What is the second sub shell
P-orbital
How many p orbitals are there
3
How many electrons can the p orbitals hold in total
6
What is the shape of an s orbital
Spherical
What is the shape of a p orbital
Dumb-bell shaped (at right angles from each other-along the x,y and z axis)
What is the third sub shell (n=3)
D orbital
How many d orbitals are there
5
How many electrons can the d-orbital hold in total
10
What is the fourth sub shell called (n=4)
The f orbital
How many f orbitals are there
7
Max number of electrons a f orbital can hold
14
Max number of electrons in the first shell
2
Max number of electrons in the second shell
8
Max number of electrons in the third shell
18
Max number of electrons in the fourth shell
32
Why can we put two negative electrons in the same orbital
They have opposite spins (on a box diagram one arrow points upward and one downward)
What is the s block in the periodic table
The first 2 groups
What is the p block in the periodic table
Groups 3,4,5,6,7,0
What is the d block in the periodic table
The transition metals
What is ionisation energy?
The amount of energy that is required to remove an electron from the metals to make them a +ve ion
Definition of the first ionisation
Removal of 1 mol of electrons from 1mol of gaseous atoms to form 1 mol of gaseous 1+ ions
