Draw the geometric atomic structure of the following atom showing the number of electrons, protons and neutrons in them:
\[\ce{^31_15P}\]
उत्तर
Geometric atomic structure of:
\[\ce{^31_15P}\]
Number of protons P = 15 = e number of electrons
A = P + n
31 = 15 + n
∴ n = 31 − 15 = 16 number of neutrons
Electronic configuration 2, 8, 5
In K shell = 2 electrons
In L shell = 8
In M shell = 5
