Verified answer

Answer:

An atom X that has 12 protons and 12 electrons, loses two electrons to form an ion. What will be charge of the ion? What will be the number of protons and electrons in the ion?

Given that:-

• An atom X has 12protons

and

• 12electrons.

It loses 2 electrons to form an ion.

We need to find the charge and the number of protons and electrons after formation of ions.

Solution:-

When the atoms loses 2 electrons then the atom comprises of 10 electrons.

Hence, the ion will have

Charge: two - unit positive charge.

• No. of proton = 12.
• No. of electron = 10.
• Valency = 2.
• Valence electron = 12.
