Key distinction – Percent diversity vs family member Abundance  

Percent abundance and relative abundance are percent values of chemical aspects that stand for their event in the environment. The an essential difference between percent abundance and also relative abundance is the percent abundance provides the abundance of isotope whereas relative abundance gives the abundance of chemistry elements. The percent abundance can be offered to recognize the mean atomic massive of a particular chemical element. Family member abundance offers the incident of a specific chemical facet in a given environment, i.e, top top earth.

What is Percent Abundance?

Percent abundance is the percentage amount of all naturally occurring isotopes of one element. Isotopes room atoms of the same element that have identical atom numbers however different massive numbers. This way isotopes room atoms having actually the same number of protons in the atom nucleus, but different numbers of neutrons.

Figure 1: isotopes of Different aspects can be offered to find their mean Atomic Masses

Isotopes of each aspect occur normally in various ratios. The percent diversity of one isotope shows the probability the finding that isotope in nature since elements can be discovered as a mixture of isotopes. The percent abundance can be offered to uncover the atomic mass the the element. The atom mass can be found using the adhering to equation.

Average atom mass = ∑ (mass the isotope x percent diversity of isotope)

Let us consider an example to understand this. The many stable, naturally arising isotopes of chlorine room Cl-35 (mass = 34.969 and percent diversity = 75.53%) and also Cl-37 (mass = 36.966 and percent abundance = 24.47%). Then,

The average mass of chlorine = ∑ (mass that isotope x percent variety of isotope)

= ∑ (34.969 x 75.53/100) + (36.966 x 24.47/100)

= 26.412 amu + 9.045 amu

= 35.46 amu.

What is family member Abundance?

Relative variety of an aspect is a measure up of the event of an element relative to every other aspects in the environment. There are three ways to determine the relative abundance of one element:

Mass fractionMole fractionVolume fraction

Volume fraction method is most typical for gaseous aspects in gas mixtures, i.e, the atmosphere of earth. However, most relative abundance expressions space mass fractions.

When considering the universe, the many abundant chemical elements are hydrogen and also helium. As soon as considering the earth, the most common facet is iron whose mass percentage is 32.1%. Other facets are oxygen (32.1%), silicone (15.1%), magnesium (13.9%), sulfur (2.9%) and also other elements are current in trace percentages.

What space the Similarities in between Percent Abundance and Relative Abundance?

Both percent abundance and also relative variety are portion values.Both percent abundance and also relative abundance to express the percentages of various chemical elements.

What is the Difference in between Percent Abundance and also Relative Abundance?

Percent Abundance vs family member Abundance

Percent diversity is the percentage amount of all naturally occurring isotopes of one element.Relative abundance of an aspect is a portion of the incident of an facet relative to every other facets in the environment.
Percent abundance provides the variety of isotopes.Relative abundance gives the diversity of chemistry elements.

Summary – Percent Abundance vs relative Abundance

Percent abundance and relative abundance space two terms offered to offer the abundance of isotopes and chemical elements. The key difference in between percent abundance and also relative variety is that percent abundance provides the diversity of isotopes whereas loved one abundance provides the variety of chemical elements.
