Atomic Orbitals video

Question 1

Atomic orbitals

Answer 1

Possible waves that fit the atomic constraints

Question 2

Principle quantum number decides: (n)

Answer 2

The size of the orbitals

Question 3

Possible quantum numbers:

Answer 3

any positive integer no zero

Question 4

angular momentum number defines (l) (3)

Answer 4

Shape of orbital
-tells u if you have s,p,d orbital
*Shape of wave depends on l

Question 4

angular momentum number defines (l) (2)

Answer 4

Shape of orbital

*Shape of wave depends on l

Question 5

Possible values of l

Answer 5

0,…(n-1)

Question 6

Magnetic quantum number (ml) defines (2)

Answer 6

orientation of the orbital
Where it is pointing

Question 7

possible ml numbers

Answer 7

-l to +l (and in between.)

Question 8

l=0 orbital describe (2)

Answer 8

s orbital
sphere

Question 9

l=1 orbital describe(3)

Answer 9

1 angular node
Formation of an orbital with two distinct part
p orbital

Question 10

describe a l=2 orbital (4)

Answer 10

2 angular nodes
sphere cut into 4
every time you cross a node, you switch phases
d orbital

Question 11

as n get bigger…
(2)

Answer 11

size increase
radial nodes increase

Question 12

describe what each value means: 2s

Answer 12

2= value of “n”
s=the shape

Question 13

what orbital has no radial nodes

Answer 13

1s

Question 14

radial node (2)

Answer 14

spherical surface region where the probability of finding an electron is zero.
determined by principal quantum number

Question 15

angular node (5)

Answer 15

flat planes (or cones) where the probability of finding an electron is zero. The number of angular node present in an atom is determined by the angular momentum quantum number. Angular nodes occur as the angular momentum quantum number increases.

cuts across
upper half and bottom half of the wave are different from each other.

Question 16

All of the orbitals with the same value of n are all in the

Answer 16

same shell

Question 17

in n=2 shell there are ___ places to put electrons

Answer 17

4

Question 18

In the n=2 shell there are ___ sub shells

Answer 18

2

Question 19

Whenever we go from one shell to another

Answer 19

there is a big jump in size

Question 20

in terms of n,spd,m what are

shell
subshell
oribital

defined by

Answer 20

shell-quantum number
subshell- spade,
orbital- m

Question 21

electrons located in the outermost level

Answer 21

have higher energy because it takes more effort and energy to pull electrons away from the centre
