Elements of Life: Electronic Structure

Question 1

What is another name for electron shells

Answer 1

Energy levels

Question 2

What do electron shells contain

Answer 2

Sub shells

Question 3

How many sub levels are there in the 1st shell

Answer 3

1

Question 4

How many sub levels are there in the 2nd shell

Answer 4

2

Question 5

How many sub levels are there in the 3rd shell

Answer 5

3

Question 6

How many sub levels are there in the 4th shell

Answer 6

4

Question 7

What is the order of subshells ( letters )

Answer 7

s, p, d, f,

Question 8

Number of orbitals in subshell s

Answer 8

1

Question 9

Number of orbitals in subshell p

Answer 9

3

Question 10

Number of orbitals in subshell d

Answer 10

5

Question 11

How many electrons can each orbital hold

Answer 11

2 electrons with opposite spins

Question 12

Max no. electrons for s subshell

Answer 12

2

Question 12

Max no. electrons for p subshell

Answer 12

6

Question 13

Max no. electrons for d subshell

Answer 13

10

Question 14

Explain Hunds Rule ( terms of how electrons fill orbitals )

Answer 14

Bus seat theory = rather sit alone if seats free than in a pair

= electrons prefer to occupy orbitals on there own = only pair up when no empty orbitals of the same energy available

Question 15

In ions what electrons are lost first

Answer 15

Electrons in the highest energy levels

Question 16

What is special about transition metals

Answer 16

Loose 4s electrons before 3d when forming ions

Question 17

Important rule to remember about 4s and 3d

Answer 17

4s = power energy then 3d = 4s orbital filled before 3d orbitals

Question 18

What is the short hand way of representing electronic configuration

Answer 18

Replace sublevels before hand with the noble gas just before the atom

Question 19

Learn sub shell blocks on periodic table

Answer 19

Look at periodic table

Question 20

How do you draw shape of an s orbital

Answer 20

As a circle

Question 21

How do you draw shape of p orbital

Answer 21

Figure of 8
