Question
Draw the geometric atomic structure of the following atom showing the number of electrons, protons and neutrons in them:
\[\ce{^39_19K}\]
Advertisements
Solution
Geometric atomic structure of:
\[\ce{^39_19K}\]
Number of protons P = 19 = e
A = P + n
39 = 19 + n
∴ n = 39 − 19 = 20
e = 19 (2, 8, 8, 1)
Electronic configuration
2, 8, 8, 1 electronic arrangement
