Question

an element x has 2 valence electrons and y has 3 valence electrons
«»Write equation for the conversion of x and y into ions
«»Name the oxidising and reducing agent
«» State
the type of bonding between x and y and give the
chemical formulă between them​

Answer 1

Answer:

1]As element X valency is 2 and element Y valency is 3 so according to cross exchange method the formula of this compound will be XY2. This method says that when elements in a compound has different valencies then in writing its chemical formula, we exchange their valencies with one another

2]Conversion Ionic equation  Oxidation/reduction  

Chloride ion to chlorine molecule 2Cl  

−

→Cl  

2

​  

+2e  

−

   Oxidation

lead(II) ion to lead Pb  

2+

+2e  

−

→Pb   Reduction

3] Unsourced material may be challenged and removed. Reducing agent (also called a reductant or reducer) is an element or compound that loses (or "donates") an electron to an electron recipient (oxidizing agent) in a redox chemical reaction. A reducing agent is thus oxidized when it loses electrons in the redox reaction.

4]E.N. difference  Type of bond

0  Nonpolar covalent

0-1.6  Polar covalent

1.7  50% covalent , 50% ionic

1.7-3.3  Mainly ionic

It is the Gallis scale that explains the type of bond with E.N. difference,

so the compound XY would be ionic if the E.N. difference between X and Y is more than 1.7.
