Question

A student has an unknown sample. How can spectroscopy be used to identify the sample?

It can identify the elements in the sample.
It can determine the number of electrons in the sample.
It can determine the ratio of the elements in the sample.
It can determine the molecular structure of atoms in the sample.

Answer 1

Answer: A. It can identify the elements in the sample.

Explanation: on edge

Answer 2

Spectroscopy is the technique used in analytical chemistry. An unknown sample can be identified by spectroscopy as it can determine the elements. Thus, option A is correct.

What is spectroscopy?

Spectroscopy is an analytical technique that can determine the atomic and molecular structure of the sample by the method of absorption and emission of the energy by the particles of the matter.

The particles or the atomic elements absorb the electromagnetic radiation from the source and emit a specific spectrum or wavelength that is a characteristic of an element.

This spectrum allows the deduction of the structural details and the electronic configuration that is used to know the element or the atom present in an unknown sample.

Therefore, option A. spectroscopy can identify the elements in the unknown sample.
