Pls ! : ) based on valence electron configurations, which of the following is the accurate formula for a compound formed from sodium (na) and oxygen (: all numerical values below are subscripts) *

The study of chemicals is called chemistry. There are two types of solution in the chemistry and these are acid and base.

The correct answer is

What are moles?

Thus sodium needs to lose one electron in order to attain noble gas configuration and Oxygen needs to gain two electrons to attain noble gas configuration.

Thus Na will lose one electron to form and Oxygen gain two electrons to form In order to form a stable neutral compound, two sodium ions are required.

Thus the formula will be .

The accurate formula is .

Explanation: Atomic no of Sodium is 11. The electronic configuration is:

Na:

Atomic no of Oxygen is 8. The electronic configuration is:

O:

Thus sodium needs to lose one electron in order to attain noble gas configuration and Oxygen needs to gain two electrons to attain noble gas configuration.

Thus Na will lose one electron to form and Oxygen gain two electrons to form . In order to form a stable neutral compound, two sodium ions are required.

Thus the formula will be .
