Question

The charge of an electron is 1.6 x 10-19C what
will be the value of charge on Na+ ion.
1)1.6 x 10-19C
2)3.2 x 10-190
3) 2.4 x 10-19C 4) 10 * 1.6 × 10-190


please calculate and explain.​

Answer 1

Answer:

1.6 × 10^-18 C

Explanation:

The charge of 1 electron is 1.6×10^-19

Na atom has 11 electrons. To attain stability, it loses one electron and form Na + cation. So the no.of.electrons in Na+ is 11-1=10 electrons.

The charge of 10 electron = 10× 1.6×10^-19 C

This can be written as 1.6 × 10^-18 C
