Which of the following statements about magnesium atoms is NOT correct? 1. All magnesium atoms have the same number of protons.
Fantom [35]

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>

DNA does help repair genes like per say you got a scrape on your leg or arm the DNA would clot so that the bleeding would stop and that would cause it to scab over.
