Question

read the article and answer the following questions. ionic bonding why did it require two sodium atoms to complete the na₂o formula unit? o na has +2 charge and o has -1 charge. o na has +1 charge and o has -2 charge. o na has -2 charge and o has +1 charge. done

Explanation:

In an ionic - compound, the overall charge of the formula unit must be zero. Sodium (Na) typically forms a + 1 ion, and oxygen (O) typically forms a - 2 ion. To balance the charges and make the overall charge of the formula unit zero, two sodium ions (each with a + 1 charge) are needed for one oxygen ion (with a - 2 charge).

Answer:

Na has +1 charge and O has -2 charge.
