Description

Current topic:

Atomic Physics, Nuclear Physics and Radioactivity

Chapters Text 30.1-31.6 Book: Concept Summary: Goes in depth about what an atom is, how it is used, and how it can be manipulated Name of Physical *Describe IYOW SI Unit Definition Formula Quantity/Concept Me= 9.11 x 10-31 kg 1 Electron Mass The weight of a single Me electron, a negatively charged particle

2

Proton Mass

3 Nuclear Decay

4 Half-life

5 Decay Constant

Scalar The weight of a single Mp proton, a positively charged particle Scalar The process by which an atomic nucleus of an unstable atom loses mass and energy by emitting ionizing particles Scalar The time in which a nucleus will decrease by 50%

E

Mp= 1.67 x 10-27 kg

E = (∆m)c2

T1/2

Scalar λ Quantity that is proportional to the half-life of a nucleus, which is used in the equation for numbers of nuclei as a function of time

λ=(0.693/t1/2)

6 Atom

7 Parent

Scalar Basic unit of matter, which consist of a positively charged nucleus and a negatively charged electron cloud that surrounds the nucleus The original state of nucleus before it starts to decay

8 Isotopes

A nucleus having the same Z (same amount of protons), but a different amount of Ns (different amount of neutrons) Problems Worked Conceptual questions from 30.1-30.9 (the first 2-3 questions), conceptual questions from 31.1-31.7 (one question from each section), the additional problems and solutions (all) **Context This chapter was about what an atom is and the Summary: studies behind the atom regarding its usage, its chemical makeup, and its life expectancy

* If you are describing a quantity also indicate if it is a vector or a scalar and indicate unit. Include the definition formula for each quantity and all formulas that might help in solving the problems on the exam. *IYOW means “In your Own Words” **What did you learn from solving the cited problems that you can use in working out new problems in the future?...
