Indium have:
to know how to get the protons, electrons and neutrons:
77 protons, 115 neutrons.
1 atom of iridium has 77 electrons in total.
Isotopes are atoms of the same element with different numbers of neutrons in their nuclei, resulting in different atomic masses. This is how there can be two different atoms of iridium.
Iridium, Einsteinium
Iridium wins when the density is calculated using the "space lattice" method, which is considered to be more accurate, when comparing it to Osmium. An atom of Iridium has 77 protons, 77 electrons and 115 neutrons. At.wt. 192.22 An atom of Osmium has 76 protons, 76 elections and 114 neutrons. At. wt. 190.2 Osmium has a crystal structure that is "Hexagonal" Iridium is a "Cubic face centred" crystal. This crystal structure is how the atoms align with each other to form the material itself. A good example to understand this is with Carbon. A very dense and very hard form is DIAMOND where the carbon atoms are very tightly and closely bonded together. A very soft form is GRAPHITE, where the carbons atoms are very loosely packed and easily parted from each other. The Iridium structure's "space lattice" is more compact than that of Osmium such that more protons, neutrons and electrons fit into a unit volume and thus it is denser.
77 protons, 115 neutrons.
If it is possible without any other nuclear reactions to be done, it'll give you an isotope of iridium.

26,4 g iridium is equal to 0,137 mol.
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.

Iridium, Einsteinium
~58 If iridium has a density of 22.42 g/cm3, 1300 grams of iridium would displace 1300/22.42 grams of water (as water has a density of 1 g/cm3). The shape of the iridium is irrelevant.

Xenon. Take the atomic mass of 131 and subtract it's protons 54, to get 77 neutrons.
How many neutrons would it have if it had 11 neutrons? 11.
