- 1Which atomic components does the nucleus of an atom contain?Protons and Neutrons
- 2An atom with a specific combination of neutrons and protons is called a___.Nuclide
- 3Which of the following pairs have the same number of protons?He-3 & He-4
- 4A general term referring to all unstable atoms is?Radionuclide
- 5The energy equivalence of one e- is511 KeV
E=m(mass of e-)c*(speed of light)^2*(1ev/1.6e-19J) - 6How many protons does 44/20Ca have?20
- 7How many neutrons does 32/15P?17
- 8How many electrons does an atom of 28/13Al have?13
- 9How much energy would be produced if 1 amu was completely transformed into energy?1 amu = 1.66E*-27kg
E = mc^2
E = (1.66E-27kg)*(3.0E8m/s^2)^2 = 1.49E-10 J
(1.49E-10J)(1eV/1.6E-19J) = 9.31E8 eV - 10The ___of an atom is calculated by multiplying the Mass Defect by the total amount of energy represented by 1 amu (931MeV).binding energy
- 11Mass Defectwhy atomic mass is always less than sum of atom's parts
