Question

question 1 (5 points)
match each item with the correct statement below.
column a

1. region of high probability of finding an electron
2. lowest energy level
3. tendency of electrons to enter orbitals of lowest energy first
4. arrangement of electrons around atomic nucleus
5. each orbital has at most two electrons

column b
a. pauli exclusion principle
b. aufbau principle
c. electron configuration
d. atomic orbital
e. ground state

Explanation:

• Atomic orbital: It is defined as the region of high probability of finding an electron.
• Ground state: Represents the lowest energy level of an atom.
• Aufbau principle: States that electrons enter orbitals of lowest energy first.
• Electron configuration: Refers to the arrangement of electrons around the atomic nucleus.
• Pauli exclusion principle: Each orbital can hold at most two electrons.

Answer:

1. d. atomic orbital
2. e. ground state
3. b. aufbau principle
4. c. electron configuration
5. a. Pauli exclusion principle
