What is the symbol and atomic number for an isotope with an mass number of 191 containing 115 neutrons?
This an isotope of osmium, osmium-191. The symbol is 19176Os.
The nucleus of an atom consists of 8 protons and 6 neutrons The total number of electrons present in a neutral atom of this element is?
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.
What element has an atomic number of 76?
Reference to a periodic table or similar reference source shows that there is such an element, and it has the name "osmium".
Has 114 neutrons within its nucleus?
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.
