Expert Answer

Step 1

Atoms have a tendency to complete their octet of 8 electrons in order to obtain the stable electronic configuration. Therefore, elements accept or donate electrons in order to complete their outermost shell of electrons.

The tendency to accept or gain electrons for an atom depends upon the stability of its electronic configuration. If an atom has a stable electronic configuration, then it has a lesser tendency to accept or donate electrons. Also, reverse is true for the case when atom has less stable electronic configuration.

Step 2

Fluorine has 5 electrons in its 2p subshell and requires only one electron to complete its outermost shell of electrons. Therefore, it has a highest tendency to accept electrons.

Oxygen has 4 electrons in its 2p subshell and requires two electrons to complete its outermost shell of electrons. Therefore, it has a lesser tendency to accept electrons in comparison to fluorine.

Carbon has 2 electrons in its 2p subshell and requires four electrons to complete its outermost shell of electrons. Therefore, it has a lesser tendency to accept electrons in comparison to fluorine and oxygen.

Step 3

Lithium has only one electron in its 2s subshell. It can have fully filled electronic configuration after donating one electron. Therefore, it has a very less tendency to accept electrons but has a high tendency to donate electrons.
