Rutherfordium.
Highly unstable element atomic number 104?
The element is called Rutherfordium. Atomic Weight: 261 g/mol Neutrons: 157 Protons: 104
What element contains 104 protons?
As far as mass, Palladium, Pd, is closest at approximately 106.4. If you meant atomic number, than Seaborgium, Sg, has an atomic number of 106
What is the element with104 neutrons?
Lutetium (Lu) has 104 neutrons To find this number for any element, take the atomic number (lutetium is 71 on the periodic table) and the mass number of the element and subtract to find neutrons. The atomic number represents the number of Protons and electrons in an atom, the mass number can be found by rounding the atomic mass. If you subtract the # of protons from the total it will tell you how many particles , or neutrons, are left in the nucleus of the atom.. The atomic mass of Lu is 174.967 amu Therefore 175 (total particles) -71 (proton particles)= 104 Neutron particles.
What is the Atomic Mass of Lutetium?
Number of neutrons = Mass number - Atomic number According to the periodic table, the "Mass number" of lutetium is 174.97, and the "Atomic number" is 71. Therefore, Number of neutrons = 174.97 - 71 = 103.97 neutrons or approximately 104 neutrons.
What is rutherfordiums atomic mass?
261 amu. ------- The most stable isotopes of rutherfordium are: - atomic mass of 265Rf: 265,116 700 - atomic mass of 267Rf: 267,121 530 Masses after IUPAC recommendations, 2009.
What is the atomic number of unnilquadium?
Unnilquadium is a placeholder name for the element with the atomic number 104. It is also known as Rutherfordium (Rf) and is a synthetic element that is created in laboratories and does not exist in nature.
4.8224X104Cg to mass in grams and in amu?
4.8224*104 Cg = 2.9041177498*1026 atomic mass unit [1998] 4.8224*104 Cg = 482.24 gram
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.
What atomic number has 104 protons?
Atomic number 104 has 104 protons.
How many protons and nertons are in Rg-272?
Rutherfordium-272 (Rg-272) has 104 protons, as indicated by its atomic number (104). The number of neutrons can be found by subtracting the atomic number from the mass number: 272 - 104 = 168 neutrons. Therefore, Rg-272 has 104 protons and 168 neutrons.
What is effective atomic number of a transition element?
Atomic numbers of transition elements are: 21-30, 39-48, 57-80, 89, 104-112.
