Chapter 21 Chemistry Review Questions
And Answers 2026 Update!!!
Who is Doris Zeul? Giganta
What are protons/neutrons scientifically called? Nucleons
What are atoms scientifically called? Nuclides
What is the mass for protons to determine mass
1.007276 amu
defect?
What is the mass for neutrons to determine
1.008665 amu
mass defect?
What is the mass for electrons to determine
0.0005486 amu
mass defect?
Multiply the mass of each (protons, neutrons,
electrons) by the number of nuclides and
electrons, and then subtract the final value from
the value that is provided in the table. Take this
value and multiply it by 1.6605 × 10^-27 kg to
How do you calculate mass defect of an element
convert the atomic mass to kg which will be
And then the Nuclear Binding Energy?
used in E = mc². Take this value, multiply it by
(3×10^8)². To find the binding energy per
nucleon, divide this value by the value of the
protons and neutrons added up. This answer is
in Joules.
What is the ideal ratio of neutron to proton for Low end; 1.5n:1p
something to be stable? Both on the low end
and the high end High end; 1n: 1p
What is the nuclear shell model? Nucleons live in “shells” energy levels
For Nuclear Reaction Transmutations, state Mass Number is On Top
where the mass and atomic numbers are placed
next to each element Atomic Number is On Bottom
