The number of neutrons in the main isotopes of osmium and their abundance is116 (41%),114 (26%),113 (16%),112 (13%)There are three more isotopes with fewer protons and abundance below 5%.
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.
Platinumit has 6 naturally occurring isotopes: 190 (78 protons and 112 neu-trons), 192 (78 protons and 114 neutrons), 194 (78 protons and 116 neu-trons), 195 (78 protons and 117 neutrons), 196 (78 protons and 118 neu-trons), 198 (78 protons and 120 neutrons).
Te2- ion
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
Te-128 has 52 protons, 52 electrons, and 76 neutrons.

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.
Osmium, if you take the Atomic Mass (190.2) and subtract the Atomic number (76), you get the result of 114, this is the number of protons, not the protons and neutrons combined.
The atomic number of tellurium is 52. So there are 52 protons and 52 electrons. the number of isotope depends on the isotope. Te-128 has 76 neutrons. Note: Mass number = number of protons + number of neutrons
Osmium atoms have 76 electrons and protons, and between 108 and 116 neutrons. The isotopes with more neutrons are more abundant.

This element is tin; for the natural isotopes the number of neutrons is between 62 and 76.
It's 53, because the number of protons equal the element's atomic number. You can easily find it on a periodic table.
