Answer:
MgO
Explanation:
A magnesium ion has a charge of +2 and an oxygen ion has a charge of –2.
Molecule made by ions is neutral . In case of Magnesium oxide molecule it is possible only when on magnesium ion and one oxide ion join together to form molecule . The total charge of molecule will be + 2 - 2 = 0 . In this way molecule formed becomes neutral . Hence formula of magnesium oxide is
MgO .
Answer:
A magnesium ion has a charge of +2 and an oxygen ion has a charge of –2. What is the chemical formula of the compound made of these ions?
-- MgO --
