There is no such isotope. The highest atomic number is 118.
The question is erroneous.
The isotope platinum-190 has the atomic number 78, the mass number 190 and the Atomic Mass 189,959 932(6).
Iridium has an atomic mass of 192 (192.217)
To convert degrees Celsius into degrees Fahrenheit, multiply the number by 9, divide by 5, and add 32. In this instance:190 x 9 = 1710 / 5 = 342 + 374Therefore, 190 degrees Celsius is equal to 374 degrees Fahrenheit.
190°f = 87.8°c
Start by taking the number in Celsius and multiply it by 9. Then divide that number by 5, and then add 32. This is how you convert Celsius to Fahrenheit or use the equation F = (9/5)C + 32In this case, the answer is about 374 degrees Fahrenheit.
Ist= 0-90 II =90 - 180 III= 180-270 IV=270-360
Iridium has an atomic mass of 192 (192.217)
Because this is an element and not an isotope, to find the number of neutrons, take the atomic mass and subtract the atomic number. Osmium has a mass of 190 and a number of 76. This equals 114.
Platinum has six naturally occurring isotopes. They range from 190 to 196 in atomic mass. There are 31 synthetic isotopes in platinum that range from 166 to 202 in atomic mass.
The only stable, and only naturally-occurring isotope of gold has mass number of 197. This is the number of protons and neutrons in each nucleus. Gold's atomic number is 79. This is the number of protons found in each gold atom. This determines its place in the periodic table, and its chemical properties: it is the defining property of gold. A nucleus with a different number of neutrons and the same 79 protons would be a different isotope with a different mass number; a nucleus with a different number of protons would not be gold, but some other element.
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 alpha particle is emitted when Pt-190 decays to Os-186. An alpha particle has a mass number of 4, and an atomic number of 2. When Pt-190 decays to Os-186, the mass number drops by 4, showing that an alpha particle is emitted, along with energy. The other form of particle that could be emitted is a beta particle, which has a mass number of 0. The difference between 190 and 186 is 4, thus showing the emission of an alpha particle.
