The radius of a copper atom is 1.3⋅10^−10m. How many times N can you divide evenly a 11.1 cm long line of copper atoms until it is reduced to a single copper atom?

Given :

Radius of copper atom , .

Length , l = 11.1 cm = 0.0111 m .

To Find :

How many times N can you divide to reduced to a single copper atom.

Solution :

Number of time cuts required is equal to total number of atoms .

Therefore , number of time we need to divide the rod is equal to .

Hence , this is the required solution .

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
