Describe the progress of the formation of an ionic bond in terms of electrons
umka21 [38]

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

A lead sphere has a mass of 1.20 x 104 g, and its volume is 1.05 x 103 cm^3. Calculate the density of lead.
Hatshy [7]

Answer: The density of lead will be 11.42g/cm^3

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Given : Mass of lead=1.20\times 10^4g

Volume of lead =1.05\times 10^3cm^3

Putting in the values we get:

Density=\frac{1.20\times 10^4}{1.05\times 10^3}=11.42g/cm^3

Thus density of lead will be 11.42g/cm^3
