Which of the following types of electromagnetic radiation has the shortest wavelength? a. gamma rays b. X-rays c. radio waves , d. infrared e. visible 5. Which of the following represents an s orbital? a. d. b. e. c. 6. Which of the following elements has the ground-state electron configuration 1s 2 2p 3s a. Al b. S c. Cl d. P e. Ar

Explanation / Answer

1. m = + l to -l

So, l = 2 will have 5 orbitals (+2, +1, 0, -1, -2)

2. Atomic spectra are due to the changes in the energy of electrons

3. A shell is defined by the n quantum number

4. Gamma rays has the shortest wavelength

5. s orbital spherical so, option a is correct
