Questions & Step-by-Step Solutions

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.
