For a: The variety of inner electrons, outer electrons and valence electrons room 28, 7 and 7 respectively.

You are watching: How many inner outer and valence electrons

For b: The variety of inner electrons, external electrons and also valence electrons space 54, 1 and 1 respectively.

For c: The variety of inner electrons, outer electrons and also valence electrons space 23, 1 and also 1 respectively.

For d: The variety of inner electrons, outer electrons and also valence electrons room 36, 2 and 2 respectively.

For e: The number of inner electrons, external electrons and valence electrons space 2, 7 and 7 respectively.

Explanation:

Outer covering electrons room the electrons which are not tightly held by the electrons. They are dubbed as valence electrons. The electrons existing in the highest possible principle quantum number are well-known as valence electrons.

Inner shell electrons room the electron which space tightly held by the electrons. Castle are dubbed as main point electrons.

Inner electron = Total number of electrons - Valence electrons

Total variety of electrons in an atom is equal to the atomic number of the element.
