The radii of most atoms are actually measured in the Ǻ, or Angstrom. We can do it in nanometers too, however.
<span>First, we take the radius of the smallest atom, He (Helium). Atomic radius = .031 nm. The largest atom, stable atom is Fr (Francium), with atomic radius = .27 nm. </span>
<span>Therefore, the typical atomic radius is between .031 and .27 nm.</span>
Answer:
Ionic Compound
Not the answer:
Metallic compounds are just made of one or more than one metal.
Ex. Chloride, Sodium Chloride
Covalent compounds only form between nonmetallic elements because these elements have the same or similar electronegativity values.
Ex. Water, Hydrogen
The correct awnser would be D , hope this helps!
Answer:
A
Explanation:
