What else can I help you with?
When masses of all naturally occurring isotopes of a particular element are averaged the result is called the elements?
When the mathematical products of the mass of each naturally occurring isotope of a particular element, each mass being multiplied by the natural abundance fraction* of the particular isotope, are added, the result is called the element's atomic weight or, if the masses are expressed in grams per Avogadro's Number of atoms, the gram atomic mass._____________________________*The abundance fraction equals exactly 0.01 times the percent abundance of the isotope.
What element has 18 protons 20 nuetrons and 18 electrons What is its atomic number?
The element with 18 protons is argon (Ar), with atomic number 18. Its mass number is calculated by adding the protons and neutrons, so 18 protons + 20 neutrons = mass number 38 for this particular isotope of argon.
Which isotope contains the greatest number of protons?
Atomic number is a measure of protons and electrons. extra or less Neutrons are what make an isotope and are not included in atomic number. therefore element with the highest atomic number will also be the isotope with the highest atomic number. on my periodic table it is lawrencium at 103. (note although this might have extra neutrons making it an isotope, it will always have the same atomic number - atomic number isn't what determines an isotope it is mass number) if you meant mass number (which is what determines an isotope), you can subtract the atomic number from the mass number to find out how many neutrons there are and determine whether it is an isotope or not
If an element has three isotopes with known masses what information is needed to find the average atomic mass of the element?
You would need to know the abundance of each isotope to find the average atomic mass of the element. The average atomic mass is calculated by multiplying the mass of each isotope by its relative abundance and then summing these values together.
What and the difference between an atomic symbol and a chemical symbol?
An atomic symbol represents a specific isotope of an element, including both the element symbol and the atomic mass number. A chemical symbol, on the other hand, is just the unique abbreviation for an element on the periodic table.
What are the atomic number and atomic mass number of?
The atomic number of an element is the number of protons in the nuclei of its atoms. Mass number is the sum of protons and neutrons in the atomic nucleus of a particular isotope of an element.
What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
How do you find the atomic number of an isotope?
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.
How is the mass number of an isotope different from the average atomic mass that is on the periodic table?
The mass number for a particular isotope of an element is a precise value. The average atomic mass for an element is the value you would measure for that element given all the isotopes it has and their abundance in the sample.
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
An isotope shares the atomic number with its element atom How does it differ from the element atom?
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
How do you decide a element is a isotope or ion?
An isotope has a different number of neutrons and therefore a different atomic mass. An ion has a different number of electrons from protons and therefore carries an electric charge
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
What element has the atomic mass of 22?
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
When the masses of all naturally occurring isotopes of a particular element are averaged the result of the elements?
When the mathematical products of the mass of each naturally occurring isotope of a particular element, each mass being multiplied by the natural abundance fraction* of the particular isotope, are added, the result is called the element's atomic weight or, if the masses are expressed in grams per Avogadro's Number of atoms, the gram atomic mass._____________________________*The abundance fraction equals exactly 0.01 times the percent abundance of the isotope.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes, the atomic mass of an element takes into account the relative abundance of each isotope of that element. This is because atomic mass is the weighted average of the masses of all isotopes of an element based on their natural abundance.
When masses of all naturally occurring isotopes of a particular element are averaged the result is called the elements?
