Chemistry Laws

Question 1

Law of Multiple proportions

Answer 1

law of multiple proportions states that when two elements form more than one compound, masses of one element that combine with a fixed mass of the other are in a ratio of small whole numbers.

Question 2

Aufbau principle

Answer 2

States that electrons occupy orbitals in order of increasing energy

1s<2s<2p….

Question 3

Pauli’s exclusion principle

Answer 3

States that no two electrons can have the same four quantum numbers.

2) the maximum number of electrons in a degenerate orbital is two.

Question 4

Hund’s rule

Answer 4

Electrons occupy singly before pairing takes place in a degenerate orbital.
