Question

model 2 - ground state orbital diagrams and electron configurations

1. examine the orbital diagrams and electron configurations in model 2. match each symbol below

a. □
i. single electron
b. ↑
ii. pair of electrons with opposite spins
c. ↑↓
iii. atomic orbital (region of space where an electron is likely to be found)
d. □□□
iv. sub - level (set of orbitals having equivalent energy)
e. 1s²2s²2p⁴
v. electron configuration

Explanation:

The box represents an atomic orbital where an electron can be found. The single - upward arrow represents a single electron. The pair of arrows with opposite spins represents a pair of electrons with opposite spins. The set of three boxes represents a sublevel of equivalent - energy orbitals. The notation like \(1s^{2}2s^{2}2p^{4}\) is the electron configuration.

Answer:

a. III
b. I
c. II
d. IV
e. V
