Question

2.
An element Y that has 17 protons and 17 electrons it gains one electron to form an
ion. What will be the charge on the ion? Write the number of protons and electron
in Y? full solution​

Answer 1

Answer:

As the element gains 1 electron it will have a charge of -1 as an electron has negative charge.

So the ion will become

${y}^{ - 1}$

The new ion will have

17 protons coz there was no change in no. of protons

18 electrons as it gained one electron
