An element on the periodic table has two naturally occurring isotopes one isotope has an atomic mass of about 10 amu the other isotope has an atomic mass of about 11 amu what is the name of this eleme?
Boron.
What is the atomic mass of the unstable isotope sulphur 35?
34.98008 AMU
The naturally occurring isotopes of sulfur have masses of 32 33 34 and 36 amu. The atomic mass of sulfur is 32.06 amu. Which of these isotopes is the most abundant?
The isotope with a mass of 32 amu is the most abundant. This can be determined by comparing the atomic mass of sulfur (32.06 amu) to the masses of the isotopes. Since the atomic mass is closest to 32 amu, this isotope is the most abundant.
Which element has its own isotope and its symbol is D?
Doofus. Atomic # - 128 Atomic mass - 320.04 amu
If the atomic mass of a carbon is 12 amu 1 mole of pure carbon will have a mass of?
If the atomic mass of a carbon is 12 amu, 1 mole of pure carbon will have a mass of 12 g. (that's the way an a.m.u. is defined: 1 a.m.u. = 1/12th of the mass of C-12 isotope atom)
What does amu measure?
amu is an anime character in shugo chara ------------------------------------------------- The atomic mass unit (amu) is 1/12 from the atomic mass of the isotope 12C in his ground state.

What is the AMU of Seaborgium?
IUPAC credited seaborgium with the mass [269]; the atomic mass of this isotope is 269,128 63(39) amu.
The naturally occurring isotopes of sulfur have masses of 32 33 34 and 36 amu. The atomic mass of sulfur is 32.06 amu. Which of these isotopes is the most abundant?
The isotope with a mass of 32 amu is the most abundant. This can be determined by comparing the atomic mass of sulfur (32.06 amu) to the masses of the isotopes. Since the atomic mass is closest to 32 amu, this isotope is the most abundant.
What is the element with the least atomic mass is hydrogen or helium?
Hydrogen's atomic mass (1 amu for the most stable isotope) is less than that of helium (4 amu).
The 1st isotope occurs 75.47 percent of the time and has a mass of 248.7 amu the 2nd isotope occurs 24.53 percent of the time and has a mass of 249.4 amu calculate the average atomic mass?
248.90

If the atomic mass of a carbon is 12 amu, 1 mole of pure carbon will have a mass of 12 g. (that's the way an a.m.u. is defined: 1 a.m.u. = 1/12th of the mass of C-12 isotope atom)
What is the nuclear charge of an atom with an atomic mass of 35amu and atomic number of 17?
The mass number of an isotope of an element is defined as the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope. The atomic number is defined as the number of protons only in the nucleus. Therefore, an atom with an atomic number. Since neutrons have no electric charge, the nuclear charge of the specified atom is 17 amu.
Calculate the average atomic mass of an unknown element that has two naturally-occurring isotopes The first isotope occurs 75.47 percent of the time and has a mass of 248.7 amu The second isotope occu?
the atomic mass is -(248.90)
How do you calculate the average atomic mass of a element?
The mass of the isotope multiplied by its relative abundance plus the the mass times abundance of other isotopes.(mass of isotope)(relative abundance) + (mass of isotope)(relative abundance) = average atomic massExample: Carbon can be naturally found as carbon- 12 or carbon- 13. The mass of carbon- 12 is 12 amu and it makes up 98.93% of naturally found carbon. The mass of carbon- 13 is 13.00335 amu, and it makes up 1.07% of naturally found carbon. So the equation to calculate the average atomic mass of carbon is:(0.9893)(12 amu) + (0.0107)(13.00335 amu) = 12.01 amu
