Question
- using the symbol readout box, figure out which particles affect each component of the atomic symbol and how the value of the numbers is determined.
\\(_{c}^{d}a^{b}\\)
| position in symbol box | term to describe this information | particle used to determine this | how the value is determined |
|---|---|---|---|
| b | \\(p^{+}+e^{-}\\) | ||
| c | atomic number | ||
| d | protons, neutrons |
- create a definition (write a complete sentence) for each of these items based on your labels from the atomic symbol chart.
Step1: Identify the meaning of each position in the atomic symbol
In the atomic symbol $_{c}^{d}a^{b}$, 'a' is the element symbol determined by the number of protons.
Step2: Analyze position 'b'
'b' represents the charge. The charge is determined by the difference between the number of protons ($p^{+}$) and electrons ($e^{-}$). A positive charge means there are more protons than electrons and a negative charge means there are more electrons than protons.
Step3: Analyze position 'c'
'c' is the atomic number. The atomic number is determined by the number of protons. So the particle used to determine it is protons.
Step4: Analyze position 'd'
'd' is the mass - number. The mass - number is determined by the sum of the number of protons and neutrons.
