On the basis of electronegativity, which of these pairs of elements is most likely to form monatomic ions?

a. Ba and O
b. Cs and Rb
c. O and F
d. Na and K

Respuesta :

Your answer would be A

A monatomic ion is an ion that is made of more than one atom and is from an element like calcium consisting of Ca²+ and a polyatomic ion that is Co²/³.

  • Many elements such as hydrogen, lithium, sodium, potassium, and magnesium consist of positively charged ions.
  • Other like fluoride, chlorine and iodine, and hydride consists of negatively charged ions.

Thus the correct option is Na and K that is sodium and potassium.
