Which of the following could have the electron configuration 2.8?

I. Sodium (Na) atom
II. Lithium (Li) ion
III. Oxygen (O) ion
IV. Neon (Ne) atom
V. Sulfur (S) ion

Respuesta :

Answer:

Sodium, Oxygen and Neon

The Ne has electronic configuration 2,8 because it has 10 electrons.

What is electronic configuration?

Three principles are used to define electronic configuration as that of the allocation of electrons among an atom's multiple orbitals.

What are electrons?

The smallest fundamental electrically charged particle would be an electron, according to definitions. What circles the atomic nucleus of an atom would be an example of an electron.

Therefore, the atomic number of Ne is 10 hence, the electronic configuration will be 2,8.
