Question
Draw the geometric atomic structure of the following atom showing the number of electrons, protons and neutrons in them:
\[\ce{^23_11Na}\]
Advertisements
Solution
Geometric atomic structure of:
\[\ce{^23_11Na}\]
Number of protons p = 11 = e
A = p + n
23 = 11 + n
∴ Number of neutrons n = 12
Electronic configuration 2, 8, 1
