Question 1

What is the correct electron configuration of a bromide ion ?

Accepted Answer

A bromide ion (Br-) has gained one electron compared to a neutral bromine atom, resulting in a full 4p subshell, making the configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p⁶.

Question 2

The magnitude of the wavelength of an electromagnetic wave is twice the magnitude of the wave's frequency .

Accepted Answer

The wavelength and frequency of an electromagnetic wave are inversely proportional, not directly proportional.

Question 9

Unlike x-ray fluorescence, a tomic absorption spectroscopy requires sample digestion .

Accepted Answer

Atomic absorption spectroscopy often requires sample digestion to convert the sample into a liquid form suitable for analysis, whereas X-ray fluorescence can analyze solid samples directly.
