The MSDS labels quickly inform the users regarding the level of hazards related to some kinds of chemicals. On the basis of the HCS (Hazard Communication Standard), the distributors, chemical manufacturers, and importers must provide the MSDS (Material Safety Data Sheets), for each hazardous chemical.
The MSDS label helps the individual to work with the chemicals in a safe manner and learns easily how to handle them carefully.

Answer:
5. All magnesium atoms have the same number of neutrons
Explanation:
Magnesium (Mg) is a chemical element. Its atomic number (Z) is 12 (number of protons in the nucleus of the Mg atom).
The Magnesium has three stable isotopes: 24Mg, 25Mg and 26Mg. All these isoforms have 12 protons in their atoms (same atomic number), however they vary in the mass number of the atom (M).
The mass number of the atom (M) is equal to the sum of protons and neutrons in the nucleus.
Based on this information we can know how many neutrons each isotope has
24 Mg = 12 protones + 12 neutrons
25Mg = 12 protones + 13 neutrons
26Mg = 12 protones + 14 neutrons
In this way we conclude that <u>not all magnesium atoms have the same number of neutrons</u>
