What element has the atomic number 77?
Well, I couldn't get any stable element with mass number of 77. However the closest ones are arsenic with mass number 75 or selenium with mass number 79. Note: All the following elements listed below have isotopes with mass number 77, but are unstable with half life ranging from a few hours to nano seconds: Nickel, Copper, Zinc, Galium, Germanium, Arsenic, Selenium, Bromine, Krypton, Rubidium, Strontium and Yttrium. If you had meant atomic number, then iridium has the atomic number of 77.
An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
What element has a mass number of 85?
Rubidium is a metal element. Mass number of it is 85.
What is the atomic number of iridium?
The atomic number of iridium (Ir) is 77.The atomic weight of Ir is 192.22 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
An atom of an element has 54 protons some of the elements atoms have 77 neutrons while other atoms have 79 neutrons what are the atomic numbers and mass numbers of the two types of atoms of this el?
The atomic number for an element with 54 protons is 54. For the atoms with 77 neutrons, the mass number would be 54 (protons) + 77 (neutrons) = 131. For the atoms with 79 neutrons, the mass number would be 54 (protons) + 79 (neutrons) = 133.
What element is Ir?
Ir is the chemical symbol for the element iridium. It is a dense, corrosion-resistant metal with a silver appearance. Iridium is commonly used in various industrial applications, such as in electronics and catalytic converters.
What is the mass number of the element Na?
Sodium is a metal element. Mass number of it is 23.
What element has 41 neutrons 36 protons 36 electrons charge unknown?
The element is determined by the atomic number - the number of protons in the nucleus. In this case, element 36 is Krypton. The mass is the sum of protons and neutrons in the nucleus. Here we have a mass of 77, and a quick check confirms that an isotope of Krypton with a mass of 77 does indeed exist.
How many neutrons are in iridium?
Indium have:protons = 49neutrons = 66electrons = 49to know how to get the protons, electrons and neutrons:protons = atomic number of the elementelectrons = protons or atomic number of the elementneutrons = mass number-atomic number
