Ответ:
In Na-23 atom having +1 charge, the number of
1) Protons = 11
2) Electrons = 10
3) Neutrons = 12
Explanation: There are 3 subatomic particles present in any nucleus: Protons, neutrons and electrons.
For a given
where, 11 = Atomic number
23 = Atomic mass
For an atom having +1 charge on it, the
Electronic configuration for
Electronic configuration for
(It will loose one electron)
Number of electrons = Sum of the superscripts in the above electronic configurationNumber of electrons = 10
Number of protons = Atomic numberNumber of protons = 11
Atomic mass = Number of protons + Number of neutronsNumber of neutrons = 23 - 11 = 12
