76
Atomic number 76 is Osmium, the densest element. Its atomic mass is 190. Atomic number tells you the number of protons, so 76 protons. Atomic mass tells you the sum of protons and neutrons, so there are 190-76 = 114 neutrons.
An osmium atom has 76 protons and 76 electrons, as the number of protons equals the number of electrons in a neutral atom. A niobium atom has 41 protons and 41 electrons. These numbers correspond to their respective atomic numbers on the periodic table.
An Osimum atom with mass number 188 has 118 protons (atomic number for Osmium). To find the number of neutrons, we subtract the atomic number from the mass number: 188 - 118 = 70 neutrons.
An atom of osmium has 76 protons in its nucleus.
an osmium atom has 76 protons.
An osmium atom has 76 of each.
An osmium atom has 76 protons.
The oxidation number of osmium in OsO3F2 is +6. In osmium trioxide (OsO3), each oxygen atom has an oxidation number of -2, so the sum of oxidation numbers of all atoms in the compound must equal the charge of the compound which is zero. Since there are two fluorine atoms each with an oxidation number of -1 in OsO3F2, the oxidation number of osmium must be +6 to balance the charges.
The barium atom has a much bigger radius.
76 of each.
By one mole of osmium, we can say that it contains 6.02 x 10 23 atom. So we can say that one osmium atom contains 76 electrons: 2, 8, 18, 32, 14, 2.
Osmium tetroxide is the chemical compound with the formula OsO4.
