Solution:

Sodium is an alkali metal and readily loses one electron to achieve a stable electron configuration.

Which of the following elements is most likely to lose an electron?

Which of the following elements is most likely to lose an electron?

Step 1: Understand that elements can lose or gain electrons to become more stable.
Step 2: Identify that sodium is an alkali metal, which means it is in Group 1 of the periodic table.
Step 3: Know that alkali metals have one electron in their outermost shell.
Step 4: Realize that losing this one electron allows sodium to achieve a stable electron configuration, similar to the nearest noble gas.
Step 5: Conclude that sodium is most likely to lose an electron because it is easier for it to lose one than to gain seven more electrons.
