Answer:
Number of proton is 11
Number of neutrons is 12
Number of electrons is 10
Explanation:
For a neutral Na, Sodium atom:
The mass number P+N = 23
Atomic number(E or P) = 11
A charged Na atom that has lost an electron is positively charged and so:
Number of proton = 11 (Still the same)
Number of neutrons = 12
Number of electrons = 11-1=10 (the atom has lost an electron)
If an atom loses electron, it becomes positively charged ie P>E
Answer:
It contains 11 protons in the nucleus.
It contains 12 neutrons in the nucleus.
It contains 10 electrons surrounding the nucleus.
The number of electrons are calculated from net charge and charge of proton (+1) and electron (–1).
12 neutrons are calculated from atomic number: 11 and mass number: 23.
