Question

Which metals have no valency​

Answer 1

Answer:

NO elements

Explanation:

Metals tend to lose electron and cannot have without a valency. But noble gases only will have no valecy. Maybe when u take an ionic bond (eg. NaCl) Na has 1+ Cl has 1-, so this 2 shares by losing and gaining make it valence less.

But in General metals connot be wothout valency.

Answer 2

Explanation:

Whatever loose electrons in outer shell is metal's valence electrons (like 1 in Na = sodium, 2 in Ca=calcium etc.) ; but non-metals whatever stabke no. (usually 8) in outer shell - (minus) electrons in the outer shell is it's valency (like Cl=chlorine has 7 electrons in the outer shell, so valency 8-7 = - 1, means Cl requires only 1 electron to become stable.
