Nano particles are very small and can not be seen with eyes measuring between 1 to 100 n m. Because of their small size, they can't be made from macroscopic tools.

<h3>What are particles? </h3>

These refers to those particles whose size lie between 1 to 100 n m. They are extremely small and often can not be seen with the eyes.

Owing to the fact that these particles are very small , they can not be created with very large  substances.

Describe the relationship between potential and kinetic energy
pashok25 [27]

We know potential energy is position relative, and kinetic energy is motion relative. The primary relationship between the two is their ability to transform into each other. In other words, potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and then back again.

Estimate the percent ionic character of the co bond. (note that the electronegativity of c is 2.5 and that of o is 3.5.)
deff fn [24]

From the calcuation, the percent ionic character of the bond is  70%

<h3>What is percent ionic character?</h3>

The term percent ionic character has to do with the degree of ionic bonding that is contained in a compound. It can be estimated from the electronegativity of each element.

We can use the formula; 100(1 - e^(-ΔEN² / 4))

EN = χB − χA * 100/1

EN = 3.5 - 1.5 = 1

100(1 - e^(-1)^2/4)

= 70%
