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>
This is a very hot and dry area. The winter can be mild and usually about 50° F (10°C). It is so hot and dry at 40 °C that fires and droughts are very common.The chaparral biome has many different types of terrain. Some examples are flat plains, rocky hills and mountain slopes. It is sometimes used in movies for the "Wild West". <span>The animals are all mainly grassland and desert types adapted to hot, dry weather. A few examples: coyotes, jackrabbits, mule deer, alligator lizards, horned toads, praying mantis, honey bee and ladybugs.

Because they are autorotrophs(they make their own food)so most organisms depend on them.
