Hich of these elements is most likely to form an ionic bond with potassium in a one-to-one ratio? P (Phosphorous)
P (Phosphorous)

Cl (Chloride)
Cl (Chloride)

S (Sulfur)
S (Sulfur)

Ar (Argo

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the answer is 0.8m.
