Answer : The correct option is, neutrons

Explanation :

Isotope : It is defined as the element that have the same number of protons but have the different number of neutrons of each of the atom.

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Number of protons

For example : Carbon - 13 isotope has mass number = 13, atomic number = 6 and the number of neutrons = 13 - 6 = 7

Hence, the isotopes of the same element have different numbers of neutrons.

Answer:

First off Life sciences are anything concerned with the study of a living organisms. So ones that would be included would be, microbiology biology, botany, zoology, ecology, genetics and medicine, from what the dictionary states

Explanation:

Biology is the natural science that studies life and living organisms. Which also includes molecular interactions, including their physical structure.

Genetics, is the study of heredity and or the variation of inherited characteristics that we get from family.

Microbiology, is the branch of science which deals with microorganisms.

Let me know if this helps, if not I'll continue researching.

Answer: The correct answer is the mass number of the most common isotope of the element is 24.

Explanation:

We are given:

An element having atomic number 12 is magnesium and atomic mass of the element is 24.305

The image corresponding will be $_{24.305}\textrm{Mg}^{12}\\\text{Magnesium}$

The number '24.305' is the average atomic mass of magnesium element.

Average atomic mass is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

$\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i$

Average atomic mass of magnesium = 24.305 amu

As, the average atomic mass of magnesium lies closer to the mass of Mg-24 isotope. This means that the relative abundance of this isotope is the highest of all the other isotopes.

The 'Mg-24' isotope is the most common isotope of the given element.

Hence, the correct answer is the mass number of the most common isotope of the element is 24.
