Answer:
The metal is Copper(Cu) and the ion is [tex]Cu^{+1}[/tex]
Explanation:
The given compound is XCl.
As the compound is saild to be a salt,Oxidation state of chlorine in the salt= -1(Oxidation state of Cl in all salts = -1)
Concept:
Oxidation state of a compound is zero(Sum of Oxidation states of all its atoms).
Now let the Oxidation state of X be x,
Using the concept,
Oxidation state of X + Oxidation state of Cl = 0
x + (-1) = 0
x = +1;
Therefore Oxidation state of X = +1,
So X lost 1 electron to form the compound XCl,
So, we can say that X originally had 29 electrons.
The only element in the periodic table with 29 electrons in the ground state is Copper(Cu).
