Well, I couldn't get any stable element with mass number of 77. However the closest ones are arsenic with mass number 75 or selenium with mass number 79. Note: All the following elements listed below have isotopes with mass number 77, but are unstable with half life ranging from a few hours to nano seconds: Nickel, Copper, Zinc, Galium, Germanium, Arsenic, Selenium, Bromine, Krypton, Rubidium, Strontium and Yttrium. If you had meant atomic number, then iridium has the atomic number of 77.
Iridium has an atomic mass of 192 (192.217)
this elemnt has an atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
The element with an atomic number that is double the atomic number of silicon is germanium, with atomic number 32. Silicon has an atomic number of 14.
The atomic number of an element is equivalent to the number of protons in its nucleus. In the case of iridium-174, the atomic number of iridium (Ir) is 77.
Iridium is a metal element. Atomic number of it is 77.
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
the symbol for iridium is Ir with an atomic number of 77
Atomic mass = 192.22
The atomic number of iridium is 77. Its symbol is Ir. It is placed in group-9 and period -6 in the periodic table.
The one with atomic number 77, which is iridium.

Ir is the chemical symbol for the element iridium. It is a dense, corrosion-resistant metal with a silver appearance. Iridium is commonly used in various industrial applications, such as in electronics and catalytic converters.
In neutral form, iridium should have 77 electrons. It also has 77 protons due to the fact that its atomic number is 77.
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
