What atom has an atomic number of 56 and a mass number of 137 amu?
Barium has an atomic number of 56 and a mass number of 137 amu
What is the mass in grams of barium in a sample of barium phosphate that also contains 10.0g of oxygen?
To determine the mass of barium in barium phosphate, we need to know the molar ratio of barium to oxygen in the compound. If we assume a 1:3 ratio between barium and oxygen in barium phosphate (Ba3(PO4)2), we can calculate the molar mass of barium and oxygen in the compound. With this information, we can find the mass of barium in the sample by subtracting the mass of oxygen from the total mass.
Which element has atomic number of 56 and mass number of 137?
The element with atomic number 56 is Barium (Ba). Given the mass number of 137, it means there are 137 total particles in the nucleus (protons and neutrons combined), so the number of neutrons for this isotope of Barium would be 137 - 56 = 81 neutrons.
An atom has an atomic number of 56 yet has a mass number of 137 amu evalution of data indicates that the element is?
The element with an atomic number of 56 is barium (Ba). However, the mass number of 137 amu does not match any known isotopes of barium. This suggests that the atom in question may be an isotope of barium that is not naturally occurring or may have been produced in a laboratory setting.
What element has a mass number of 138 and atomic number of 56?
The element with a mass number of 138 and atomic number of 56 is Barium (Ba). The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number indicates the number of protons. In this case, Barium has 56 protons and 82 neutrons (138 - 56 = 82).
What is the atomic mass number in barium?
The mass number is the sum of protons and electrons in the atomic nucleus of an isotope. Barium has many isotopes and each has another mass number.
What is the atomic number and atomic mass number of barium?
The atomic number of barium is 56. It has naturally occurring isotopes with mass numbers of 130, 132, 134, 135, 136, 137, and 138.
How many subatomic particles does barium have?
Barium has 56 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a barium isotope = Mass number - 56
How many neutrons are contained in an atom of barium - 136?
The atomic number of barium is 56. So there are 56 protons and 56 electrons.
How many grams barium hydroxide?
get the volume of the chemical and the mass and divide the mass by it's volume
How many neutrons does Barium -140 have?
Barium-140 has 82 neutrons. This is calculated by subtracting the atomic number (56) from the mass number (140).
What atom has an atomic number of 56 and a mass number of 137 amu?
