atomic number = 17
mass number = 37
The symbol Po-210 represents the isotope of Polonium with a mass number of 210.
You think probable to an isotope.
The symbol for all the isotopes of uranium is U. A number is added after U - the atomic mass of a specific isotope; for example U-235, U-240, etc.
The mass number of zirconium-98 is 98 by definition: The number after a hyphen in the name of an isotope is the mass number of the isotope.
The atomic number 35 corresponds to bromine, and the symbol would be 81Br.
This an isotope of osmium, osmium-191. The symbol is 19176Os.
Si
The chemical symbol of actinium is Ac.The symbol of an isotope:- as superscript to the left of Ac is the atomic mass of the isotope- as subscript to the left of Ac is the atomic number 89
You are looking for the symbol of cesium (Cs) and indication of its mass number. The mass number is the sum of the protons and neutrons. So if every atom of cesium has 55 protons, then the mass number of this isotope is 137. The mass number is indicated in superscript before the symbol: 137Cs
A = mass number z = atomic number so this one is a Ni isotope with a mass of 64
An example with a zinc isotope: 81Zn (mass number as superscript before the chemical symbol)
C15
The symbol Po-210 represents the isotope of Polonium with a mass number of 210.
Mass number is the number of protons and neutrons in the atomic nucleus of an isotope. In order to answer this question, you need to know the number of neutrons.
The mass number 5 is not compatible with the number of neutrons 10.
28/14 Si Its the number they give you which is the atomic mass of the isotope over the atomic number and the symbol of the element.
You think probable to an isotope.
