That element is Indium (In) and it's not a commonly encountered element in chemistry.
Ununpentium, with the chemical symbol Uup, has the atomic number 115.
An isotope of indium has 77 protons and 115 neutrons. What is the mass number of this isotope
From the periodic table, indium, In, has an atomic number of 49. Indium's atomic number is always 49, regardless of any isotopes.
Element 115 is Ununpentium, or Uup. It is also known as eka-bismuth. It is a placeholder in the periodic table, and we have not been able to synthesize more than 30 or so atoms of it since 2004. All of its half-lives are very short.
112th element is at current Ununbium. This will change soon though the German scientists who discovered the element have been allowed time to give it a more "personal" name before it is officially added to the periodic table.
Indium, atomic number 49, so 49 Protons. Atomic mass 115, so 115-49 = 66 Neutrons.
This an isotope of osmium, osmium-191. The symbol is 19176Os.
Ununpentium, with the chemical symbol Uup, has the atomic number 115.
An isotope of indium has 77 protons and 115 neutrons. What is the mass number of this isotope
The number 115 is the mass number, so the mass is 115 amu. One amu (atomic mass unit) is about 1.66 x 10-27 kg, so if your looking for the mass of one atom of In-115, multiply 1.66 x 10-27 kg by 115. That's about 1.9 x 10-25 kg. You chemistry teacher should have taught you this, and probably did, if you were paying attention in class.

From the periodic table, indium, In, has an atomic number of 49. Indium's atomic number is always 49, regardless of any isotopes.
Ununpentium is the temporary name of a synthetic superheavy element in the periodic table that has the temporary symbol Uup and has the atomic number 115.
protons 114 electrons 114 number of neutrons: atomic mass of an isotope - atomic number of the element; Uuq has many isotopes, each with a different number of neutrons.
Ununpentium has 115 protons in the nucleus.
Element 115 is Ununpentium, or Uup. It is also known as eka-bismuth. It is a placeholder in the periodic table, and we have not been able to synthesize more than 30 or so atoms of it since 2004. All of its half-lives are very short.
The last metal in the periodic table that is available in nature is uranium with atomic number 92.The newly discovered element, that doesn't have an official name yet, so scientists are calling it ununpentium, based on the Latin and Greek words for its atomic number, is having atomic number 115. The man-made 115 was first created by Russian scientists in Dubna about ten years ago.
