Electronic Structure

Question 1

What does the Bohr model of an atom propose

Answer 1

That electrons move around the nucleus following orbits

arranges in orbits called shells which have different energy levels

Question 2

How does quantum theory relate to electrons

Answer 2

exact position of an electron is impossible to know

Question 3

How many electrons can an S sub level hold

Answer 3

S sub-levels can have up to 2 electrons

Question 4

How many electrons can a P sub level have

Answer 4

P sub level can have up to 6 electrons

Question 5

how many electrons can a D sub level hold

Answer 5

D sub level can have up to 10 electrons

Question 6

How many electrons can a F sub level hold

Answer 6

F sub level can have up to 14 electrons

Question 7

What does the aufbau principle say about electrons

Answer 7

they first occupy the lowest energy sub level that is available, so the order of filling the sub levels is in order of increasing energy

Question 8

How many electrons does an orbital hold

Answer 8
