Answer:
Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions. The structure of metallic bonds is very different from that of covalent and ionic bonds. While ionic bonds join metals to nonmetals, and covalent bonds join nonmetals to nonmetals, metallic bonds are responsible for the bonding between metal atoms.
In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. The electrons then move freely throughout the space between the atomic nuclei.
Explanation:
Explanation:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
Answer:
The right choice is → a reduction reaction
Explanation:
From the balanced equation
- 3CIO⁻₍aq₎ → CIO⁻ ₍aq₎ + 2Cl⁻ ₍aq₎
we can calculate the change in oxidation number of Cl in reactant and product
in reactant ClO⁻
let x= oxidation number of Cl
and oxidation number of oxygen in its compound is (-2)
and the total charge on the ClO⁻ ion = -1
- ∴x + (-2) = -1 →→→ x = +1
in product Cl⁻
let x= oxidation number of Cl
and the total charge on the Cl⁻ ion = -1
so the oxidation number of Cl decreases from +1 in reactant to -1 in product so it is reduction reaction.
But, disproportionation reaction is defined as the chemical reaction in which a single substance gets reduced as well as oxidized.
For a disproportionated substance , it should contain at least three oxidation states. which isn't the case here.
<u>So, the right choice is: </u>
→ a reduction reaction
