Question

estimte charge on 10 gm copper ​

Answer 1

The number of atoms in given copper:

63.5

6.023×10

23

×3.11

Given, atomic number of copper =29

So, each atom contains 29 protons and 29 electrons.

So, the positive or negative charge on it =±

63.5

(6.023×10

23

×3.11)×29×1.6×10

−19

=±1.37×10
