Answer:
I believe the answer is the last one answer D: Neutral elements
Explanation:
Ionic bonds are formed through the exchange of valence electrons between atoms, typically a metal and a nonmetal. ... Ionic compounds are typically neutral. Ionic compounds generally form between elements that are metals and elements that are nonmetals.

Answer:
Biolage is the answer
Explanation:
Because it's price is third most
The molecules in gas are farther apart and have more room to bounce around than liquid
The mass of an element listed in the Periodic Table is the weighted average of all its naturally occurring isotopes.
Naturally occurring carbon is about
99 % carbon-12 (12.000 u) + 1 % carbon-13 (13.003 u).
That extra carbon-13 makes the <em>average atomic mass</em> greater than 12.000 u.
Answer is: D. Cl (chlorine).
The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
Barium, potassium and arsenic are metals (easily lost valence electrons), chlorine is nonmetal (easily gain electrons).
Alkaline metals (in this example, potassium) have lowest ionizations energy and easy remove valence electrons (one electron), earth alkaline metals (in this example, barium) have higher ionization energy than alkaline metals, because they have two valence electrons.
Nonmetals (in this example chlorine) are far right in the main group and they have highest ionization energy, because they have many valence electrons.
