Explanation:
The gamma-ray emitting technetium-99m (metastable) is widely used for medical diagnostic studies. Several chemical forms are used to image different parts of the body. Technetium is a remarkable corrosion inhibitor for steel, and adding very small amounts can provide excellent protection.
hope that helps you :)

Answer:</h2><h2>The primary requirement for good melting point determination is that the sample be in a fine powder form. This makes the heat transfer into the sample more efficient and reproducible, and also enhances the overall reflectivity of the sample for easier automated detection of the melt</h2><h2 />
Answer:
In Cl, the 2 is a subscript because it indicates there are 2 of the same elements. The Lewis structure would display it as Cl-Cl.
On the other hand, a superscript would indicate a specific charge.
All subscripts show the amount of the specific element there is.
An example would be O or N, they both show that there are 2 of the same elements.
If the subscript is outside a parenthesis such as it indicates there are 2 molecules.
