The danger from radon gas would most likely be greatest in well-insulated homes. It is a toxic gas.
<h3>What is radon gas?</h3>
Radon is a naturally radioactive gas generated from different elements such as uranium or radium.
Radon is generated when these radioactive materials naturally decompose in the soils and/or rocks.
Radon is highly toxic and therefore this gas must be avoided to maintain healthy conditions in a home.

Answer:
(a) 5s. n = 5. Sublevel s, l = 0. Number of orbitals = 1
(b) 3p. n = 3. Sublevel p, l = 1. Number of orbitals = 3
(c) 4f. n =4. Sublevel f, l = 3. Number of orbitals = 7
Explanation:
The rules for electron quantum numbers are:
1. Shell number, 1 ≤ n
2. Sublevel number, 0 ≤ l ≤ n − 1
So,
(a) 5s. n = 5, shell number 5. Sublevel s, l = 0. Number of orbitals = 2l +1 = 1
(b) 3p. n = 3, shell number 3. Sublevel p, l = 1. Number of orbitals = 2l +1 = 3
(c) 4f. n =4, shell number 4. Sublevel f, l = 3. Number of orbitals = 2l +1 = 7
