Question

An isotope contains 11 protons, 10 electrons, and 12 neutrons.
What is the identity of the isotope?

Answer 1

Answer:

Ne-20 (with 10 protons and 10 neutrons) Ne-21 (with 10 protons and 11 neutrons) Ne-22 (with 10 protons and 12 neutrons)Follow-Up #1: Atomic properties of Neon

90% of the neon atoms contain 10 neutrons. There are a few with 11 neutrons and around 9% with 12. Those with extra neutrons are called isotopes, the nucleii having 10 protons but a few with different numbers of neutrons

Answer 2

Number of proton =11

No. of neutron =12

No. of electron =10

Atomic number z=11

Element =Na

particle →Na

+

(due to less electrons then proton)
