Given information

Here the given information is:

Each core electron reduces the effective nuclear charge by one unit.

We have to determine the effective nuclear charge felt by the valence electrons of 'Ca'.

Step-by-step explanation

Step 1.

 

The electrons which are not valence electrons and are present in an atom can be defined as core electrons. Such electrons do not participate in bonding and are tightly bound to the nucleus.

 

Valence electrons are found to be present in the outermost shell of an atom and such electrons are responsible for the formation of bonds between the atom.
