How many neutrons protons and electrons does fermium have?
Fermium has 100 protons and electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of fermium is 100; but fermium has 17 isotopes, each with a different number of neutrons. For the most stable isotope of fermium, 257Fm: protons-100 electrons-100 neutrons-157 atomic mass per unit (AMU)-257
How many protons and electrons and neutrons does berkelium have?
Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of berkelium is 97.Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of berkelium is 97.
How many neutrons dose seaborgium 263 have?
Seaborgium-263 has 157 neutrons.
If an atom has 43 electrons and 56 neutrons and 43 protons what is its approximate atomic mass?
Atomic mass of an element is measured in atomic mass units (amu), and is usually only slightly higher than its atomic mass number (except for elements having many different isotopes). The mass of a neutron is 1.00866 amu and the mass of a proton is 1.00728 amu. The mass of electrons is so insignificant that they are ignored. The atomic mass of an atom with 56 neutrons and 43 protons is (56 x 1.00866 amu) + (43 x 1.00728 amu) = ~99.8 amu.
Mendelevium -256 and mendelevium-258 what is the difference between the nuclei of these two isotopes?
Mendelevium 256 has 155 neutrons and mendelevium 258 has 157 neutrons.
What is the mass number of an ion with 105 electrons 157 neutrons and a 1 charge?
You mean a charge of +1? That would mean that it has 106 protons. That element is seaborgium. The atomic mass, however, can be calculated by a combination of protons and neutrons. 106+157=263. The particle you speak of, seaborgium 157, has an atomic mass of 263.
What is the mass number of an ion with 105 electrons and 157 neutrons and a plus 1 charge?
The problem statement that the ion has a plus 1 charge means that there is one more proton than electron in the ion. Therefore, the ion contains 106 protons and 157 neutrons and thus has a mass number of 106 + 157 or 263 amu.
Highly unstable element atomic number 104?
The element is called Rutherfordium. Atomic Weight: 261 g/mol Neutrons: 157 Protons: 104
How many neutrons does nobelium have?
157; you figure that out by taking the atomic mass (259) and subtract it by the # of protons (102) and the answer is the # of neutrons. ( the atomic #, # of protons, and # of electrons are always the same # 102 ). But each isotope of nobelium has a different number of neutrons, depending on the atomic mass.
What is the number of neutrons in The element fermium?
157
How many neutrons does the element Ds have?
Darmstadtium is an artificial element; no stable isotopes exist. From Wikipedia: "Eight different isotopes of darmstadtium have been reported with atomic masses 267, 269-271, 273, 277, 279, and 281, ..." The numbers are protons + neutrons. Subtract 110 (the atomic number for this element) to subtract the protons, and get the number of neutrons for the different isotopes. In other words, between 157 and 171, depending on the isotope.
How many neutrons protons and electrons does fermium have?

Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of fermium is 100; but fermium has 17 isotopes, each with a different number of neutrons.

How many protons and neutrons does Mendelevium have?
Mendelevium is element 101, so it has 101 protons. Several isotopes are known, with atomic masses ranging from 245 to 262, hence from 144 to 161 neutrons. The most stable, with half-lives measured in weeks rather than hours or less, have atomic mass 258 and 260, thus 157 and 159 neutrons.
How many protons and electrons and neutrons does berkelium have?
Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of berkelium is 97.Number of neutrons = Atomic mass of an isotope - atomic number of the element The atomic number of berkelium is 97.
How many neutrons are in mendelivium?
For Md-258 isotope, there are 157 neutrons (258 - 101 = 157; atomic number = 101)
How many neutrons dose seaborgium 263 have?
Seaborgium-263 has 157 neutrons.
