200分求一道物理题,求懂英文的高手来帮下忙A certain isotope has 80 protons and 122 neutrons in its nucleus.Identify the element involved and find the atomic and mass numbers.Atomic number=Mass number=
Find the relative mass of any atom by adding the number of protons to the number of neutrons. Hydrogen has a relative atomic mass of 1, and carbon-12 has a relative atomic mass of 12. Isotopes of the same element have different numbers of neutrons, so you need to calculate for one spe...
18 is not 17.65625 Average atomic mass is dependent upon the abundance of each isotope What is an isotope? An atom with a different number of neutrons Different isotopes of an element all of the same number of protons
The element's symbol: N 1. One atom of the element above contains a. ___ protons b. ___ neutrons c. ___ electrons d. ___ atomic mass 2. ___ is the element's name. 3. How many isotopes are there? List the isotopes. 4....
The atomic weight is an average of the isotopes of the element, so that's why it's not usually a whole number.[7] 5 Subtract the atomic number from the atomic mass. Since the vast majority of an atom’s mass is made up of its protons and neutrons, subtracting the number of proton...
