The radius of a copper (cu) atom is roughly 1.3 x 10^-10 m. how many times can you divide evenly a 10-cm-long piece of copper wire until it is reduced to two separate copper atoms? (assume there are appropriate tools for this procedure and that copper atoms are lined up in a straight line, in contact with each other. round off your answer to an integer.)

We can divide the 10 cm long wire 384,615,383 times.

Explanation:

Length of the copper wire ,L= 10 cm

1 m = 100 cm

Radius of the copper atom =

Diameter of the copper atom,d =2 × r

Number of carbon atoms in the wire be n

atoms

Two copper atoms are connected by link, then n atoms will be:

Number of links in copper wire = (n - 1)

We can divide the 10 cm long wire 384,615,383 times.

there are two significant figures.
