Hydrogen gas “fire quickly in the Hindenburg accident. In comparison, neon gas and helium gas are non-reactive. This is why helium is safe for F aircraft, and neon is safe for electrical signs. Which statement best explains why helium and neon have similar chemical properties?

Answer:

They have the same number of valence electrons.

Explanation:

As a rule of thumb, elements with the same chemical properties must have the same number of valence electrons. This is why elements in the same group have similar chemical properties.

  • Chemical properties are predicated on the number of valence electrons in an atom.
  • Atoms reacts with other atoms using the number of valence electrons they contain.
  • Helium and neon are in the same group with 8 valence electrons.
  • The valence electrons are the outermost electrons in an atom.
