What is the name of the isotope that has 7 neutrons and 6 electrons?
The natural isotope of carbon 13C (abundance 1,1 %) has 6 protons, 6 electrons and 7 neutrons.
How does relative abundance relate to mass?
Biodiversity
The atomic mass of an atom is equal to the sum of the numbers of what?
The mass number of an atom is the average of all it's isotopes in ratio to how often an isotope occurs naturally (abundance). An isotope is a variant of an element that has a different number of neutrons, therefore causing the atom to have a different mass. The percent abundance of an isotope is converted to a fraction, and multiplied by the mass of the isotope. Then all the factional masses of different isotopes are added together. Atomic mass = (mass isotope 1)x(fractional natural abundance of isotope 1) + (mass isotope 2)x(fractional natural abundance of isotope 2) + (mass isotope 3)x(fractional natural abundance of isotope 3) For example: Hydrogen has 3 naturally occurring isotopes: Protium - Abundance - 99.985% (.99985) Mass - 1.0078 Deuterium - Abundance - .015% (.00015) Mass - 2.014 Tritium - Abundance - 0% (.000) Mass - 3.016 Atomic mass number of Hyrdogen = (.99985)(1.0078) + (.00015)(2.014) + (.000)(3.016) = 1.00795 Go look up the mass number of Hydrogen on the periodic table and it says 1.008
How many isotopes of gallium are there?
Natural gallium has 2 stable isotopes
What is the mass number of the most common isotope of carbon?
As the atomic number of nitrogen is 7, the most abundant isotope of this atmospheric gas must have 7 neutrons (14.007 - 7 = about 7), and this will make nitrogen-14 that isotope that is most abundant.
What is the formula to find the natural abundance?
In chemistry, natural abundance refers to the abundance of isotopes of a chemical element that is naturally found on a planet. Its formula is given as: abundance of isotope = average atomic weight of the element / exact weight of isotope.
What is is relative abundance?
The concentration of each isotope of a natural chemical element.
If an element has three isotopes with known natural abundance percentages what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
What does the relative abundance tell you?
The concentration of each isotope of a natural chemical element.
What is the name of the isotope that has 7 neutrons and 6 electrons?
The natural isotope of carbon 13C (abundance 1,1 %) has 6 protons, 6 electrons and 7 neutrons.

What is an isotope with 14 protons and 16 neutrons?
The natural stable isotope of silicon, 30Si, has 14 protons and 16 neutrons.

What is the natural abundance of 63cu?
The natural abundance of 63Cu is about 69.17%.
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.
