Identify the type of bonding in solid potassium.
Answers
The answer is: metallic bonding.
Potassium (K) is alkaline metal.
Metallic bond is a type of chemical bond.
Metallic bond is formed between electrons and positively charged metal ions.
Metallic radius is defined as one-half of the distance between the two adjacent metal ions.
Metallic bond increace electrical and thermal conductivity.
Metals conduct heat, because when free moving electrons gain energy (heat) they vibrate more quickly and can move around.
is present in solid potassium.
Further Explanation:
The chemical bond is a link or connection between the atoms present in molecules or between ions and molecules in the crystals. It is responsible to hold the chemical substances together and for the formation of chemical compounds.
Types of chemical bonds:
Covalent bond
This is also known as a molecular bond. It is the chemical bond that results from the electron sharing between the atoms. The compounds resulting from such bonds are called covalent compounds.
Ionic bond
The type of chemical bond that is formed due to the transfer of electrons from one atom to the other is an ionic bond. Ions are produced in the formation of such bonds. The electropositive element forms cations by the loss of electrons while anions are formed by the electronegative element.
Metallic bond
As is evident from its name, this bond exists in metals. Here, electrons are delocalized throughout the metal and are not only shared between two atoms. So the free electrons are present within the sample. Due to the presence of free electrons, metals have high conductivity. This bond is an attraction between the positive ions and the electrons of the same metal.
Potassium belongs to group 1A of the periodic table that is located at the extreme left region of the table. Since metals are present at the leftmost part of the periodic table, potassium is an alkali metal. So metallic bonding is present in solid potassium.

Answer:
Selling price of watch A and watch B= Rs. 425
Let cost price of watch A=x
Profit =10%
∴

For number one, the reaction is the neutralization of a strong acid and a strong base to yield a salt and water. The strong acid is the HCl and the strong base is NaOH. The salt is NaCl.
For number two, the equation is balanced. Na in the reactant side has one atom and also in the product side. O has only one atom in the product and in the reactant. There are 2H’s in the reactant and in the product side (present in H2O, the 2 in H stands for 2 atoms of H). One atom of Cl is present in the reactant and product side.
For number three, the reactants are NaOH-sodium hydroxide and HCl-hydrogen chloride(hydrochloric acid). The products are NaCl-sodium chloride and H2O-water.
