part b\nwhich statement is true regarding main - group families of the periodic table?\na argon is a noble gas that gains 1 electron to become an anion to become stable.\nb flourine is a chalcogen that gains 1 electron to become an anion to become stable.\nc lithium is an alkali metal that loses 1 electron to become a cation to become stable.\nd magnesium is an alkaline earth metal that loses two electrons to become an anion to become stable.

Answer

Brief Explanations:

  • Noble gases like argon already have a full - outer electron shell and do not gain electrons to become anions.
  • Fluorine is a halogen, not a chalcogen.
  • Lithium, an alkali metal, has 1 valence electron and loses it to form a cation and achieve a stable electron configuration.
  • Magnesium loses two electrons to become a cation, not an anion.

Answer:

C. Lithium is an alkali metal that loses 1 electron to become a cation to become stable.
