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)
What is the atomic mass of roentgenium?
The atomic mass of the most stable isotope of Roentgenium is 281. This most stable isotope decays in around 36seconds. Oddly, it's most stable isotope has the same atomic mass as the most stable isotope of the element before: Darmstadtium.
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
What does the atomic mass equals the number of?
An isotope's mass number is the sum of the protons and neutrons in each atomic nucleus of the isotope.
How may neutrons does neon have?
Number of neutrons = Atomic mass - Atomic number Atomic number of neon: 10 Atomic mass: depending on the neon isotope, each isotope has a different mass
The table below gives the atomic mass and the abundance of the two naturally occurring isotopes of chlorine. Which numerical setup can be used to calculate the atomic mass of the element chlorine?
To calculate the atomic mass of chlorine using its naturally occurring isotopes, you can use the formula: Atomic mass = (abundance of isotope 1 × atomic mass of isotope 1) + (abundance of isotope 2 × atomic mass of isotope 2). In this case, you would multiply the atomic mass of each isotope by its respective abundance (expressed as a decimal) and sum the results to find the weighted average atomic mass of chlorine.
What is the atomic mass of einstenium?
The most common isotope is einsteinium-253. So atomic mass is 253 for the most common isotope
What is the mass of the isotope 195Au?
195Au is an isotope of gold with a half life of about 186 days. It decays into 195Pt, an isotope of platinum. Its mass is 194.97 atomic mass units.
What is the defined atomic mass in amu of this isotope?
The atomic mass of an isotope is the weighted average mass of all the isotopes of that element based on their natural abundance. It is expressed in atomic mass units (amu).
How can you dertermine the number of neutrons in a isotope?
Subtract the atomic number of the isotope from its atomic mass number to obtain the number of neutrons in an isotope.
How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
