Answer:

Option A. Na⁺

Explanation:

Floride ion (F¯) simply indicates that the fluorine atom has gain an extra electron.

Thus, the electronic configuration of the fluoride ion (F¯) can be written as follow:

F¯ (10) => 1s² 2s²2p⁶

Next, we shall determine the electronic configuration of the element given in options to see which is the same as that of the fluoride ion (F¯). This is illustrated below:

Na⁺ (10) => 1s² 2s²2p⁶

Na (11) => 1s² 2s²2p⁶ 3s¹

Cl (17) => 1s² 2s²2p⁶ 3s²3p⁵

Cl¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶

From the above illustrations, we can see that the fluoride ion (F¯) has the same electronic configuration as Na⁺.

Each element is made up of electrons and these electrons are filled in different shells. These are the following shells in the electrons:

  • K shell
  • L shell
  • M shell
  • N shell

According to the question, the fluoride ion has 10 electrons in its 2 shells, that is 2 in K shell and 8 in L shell.

A similar number of shell and electrons to the fluoride ion is sodium ion ([tex]Na^{+}[/tex])

The [tex]Na^+[/tex]has a total 10 number of electrons, hence the electronic configuration is 2 and 8.

Therefore, the [tex]Na^+[/tex] is the correct option.
