An atom of an element contains 66 electrons. What element is it?
Dysprosium, atomic number 66 on the periodic table.
Dysprosium has atomic number 66 so would normally have 66 electrons.
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
A neutral atom with 49 protons must have 49 electrons. This element is Indium. there are two naturally occurring isotopes, 113 and 115 atomic weights, with 64 and 66 neutrons. 49 electrons are arranged in shells with 2, 8, 18, 18, 3 per shell.In 115 is radioactive but with a very long halflife. see Wikipedia entry for Indium.In an atom, the proton and electron number is always the same so the amswer to your question is 49
The element with the atomic number 66 is dysprosium with the symbol Dy.
Like all Zinc isotopes, Zinc-66 has 30 protons and 30 electrons. It has 36 neutrons, which is why it is called zinc-66. 30+36=66.
The element (or particular atom) with 48 protons 48 electrons in it, is always with the atom number 48 (same as proton number).So it is Cadmium, symbol Cd, belonging to group 12, period 5 (d-block transition metals) in the periodic table.If it has 66 neutrons one should look after one of the possible isotopes mass number 114, because 66 neutrons + 48 protons = 114 mass number.So this is the one to be: 110Cd, appearance >29% from total occurring natural isotopesStable, though expected to be radioactive: double beta decay, but its halftime is very long.
See the Web Links for the stable isotopes of Si (subtract 14 from the number after "silicon" -- so for example silicon-30 has 16 neutrons).A neutral Si atom has 14 electrons.See the Related Questions to the left for how to determine the number of protons, neutrons and electrons in ANY atom!
30 protons and 30 electrons as the atomic mass of zinc is 30. Zn-66 isotope has 36 neutrons
Element 66 (Dysprosium) is NOT a non-metal it is a rare earth metal, it is a solid
The Atom Clock has 66 pages.
Indium, (In) atom number 49, has:49 protons (same as atom number)49 electrons (same as protons in the UNcharged neutral atom)113-49=64 neutrons in In-113 isotope or 115-49=66 neutrons in In-115 isotope,both are natural occurring isotopes of In (5% and 95% respectively).
Dysprosium has an atomic number of 66.
30 electrons. Zinc-66 stands for Zinc having 66 as the Atomic Mass. We know Zinc has 30 protons and we can assume that it's in a stable state so there would be 30 electrons. This means there's 36 neutrons. (30[protons] + 36[neutrons] = 66[atomic mass]
66 - 30 = 36
well, the isotope number of the atom doesnt matter, as long is it doesnt decay, as it only specifies the number of neutrons which doesn't have a strong affect on the stable number of electrons. Typically, free atoms are stable when they have a netral net charge, Though, if excited with EM waves, the electrons will want to increase in energy, and eventually leave the atom.For any atom, the number of electrons is simply the atomic number, which for zinc is 30.though, when zinc is in close proximity to itself or other metals, it bonds metallically, and looses its electrons to have a full p orbital, meaning that the only number of electrons actuall in the atom is 18when in ionic bond it looses two electrons, and then only has 28 electrons
An atom's atomic number tells us its number of protons. Checking the periodic table, we see that dysprosium's atomic number is 66. Thus, it is the element with 66 protons.
Zinc-66 or 66Zn consists of 36 neutrons and it is stable
Protons=33 electrons=42 neutrons=66
Element 39, "Y", Yttrium Element 66, "Dy", Dysprosium Element 70, "Yb", Ytterbium
66. Octane is C8H18. therefore the total number of electrons is 6*8 + 18*1
