Which of the following ions can be detected using flame photometry?

Step 1: Understand what flame photometry is. It is a technique used to measure the concentration of certain metal ions in a sample by observing the color of the flame produced when the sample is heated.
Step 2: Identify the types of ions that can be detected. Flame photometry is particularly good at detecting alkali metals (like sodium and potassium) and alkaline earth metals (like calcium).
Step 3: Remember some examples of ions that can be detected: sodium (Na+), potassium (K+), and calcium (Ca2+).
Step 4: Conclude that if you are asked which ions can be detected using flame photometry, you can confidently mention sodium, calcium, and potassium.
