1 atom of iridium has 77 electrons in total.
Iridium (Ir), has 77 electrons. The atomic number is equal to the number of protons and since Ir is neutrally charged, equal to the number of electrons.
Iridium's atomic number is 77. Thus it has 77 positively charged protons. To balance out those charges, we find that iridium also has 77 negatively charged electrons.

77 protons, 115 neutrons.
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
Iridium, Einsteinium

Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier

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.

Iridium, Einsteinium
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.

Xenon. Take the atomic mass of 131 and subtract it's protons 54, to get 77 neutrons.
~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.
Lead has a higher atomic number than iridium, which means a lead atom is heavier than an iridium atom. however iridium is denser, therefore if you had a block of iridium and a block of lead,the iridium block would be heavier
