Question

During the formation of the compound sodium chloride, the correct symbol and charge for each of the ions must be...

O Na+1 and Cl-1
O Na+1 and F-1
O Na+1 and Br-1
O Na+1 and O-2

Answer 1

Answer: The correct answer is option A.
`Na^+\text{ and }Cl^-`

Step-by-step explanation:

An ionic compound is defined as the compound formed by the complete transfer of electrons from one element (forming cation) to another element (forming anion)

Sodium (Na) is an element having atomic number 11 and its electronic configuration is
`1s^22s^22p^63s^1`

It will loose 1 electron to form
`Na^+` ion (cation)

Chlorine (Cl) is an element having atomic number 17 and its electronic configuration is
`1s^22s^22p^63s^23p^5`

It will gain 1 electron to form
`Cl^-` ion (anion)

The ionic compound so formed will have the chemical formula of NaCl.

Hence, the correct answer is option A.
`Na^+\text{ and }Cl^-`
