Why magnesium oxide has a higher melting point than phosphorus oxide?

Sulphur dioxide is a covalent compound with a v-shaped structure. Because of this, the molecule is polar and can bond to other molecules due to permanent dipoles, which are relatively strong bonds. Magnesium oxide, on the other hand, is an ionic compound that forms an ionic lattice - due to the attraction between the positive Mg and negative O ions. Because of this, there are strong intermolecular bonds that hold the molecules more tightly together than permanent dipole and so more energy is required to break them than in SO2

∙ 14y agoit is because the charge of the magnesium ion is 2+and oxide ion is 2- they attract each other more strongly than sodium ion is 1 and chloride ion is 1-.

What relationships are there between magnesium and magnesium oxide?
Magnesium is an element. Magnesium oxide is a compound formed from magnesium and oxygen. Magnesium oxide often serves as a magnesium supplement.
Which is more basic Mgo why.?
the answer is BaO..... because the barium is occupy the lower position than the magnesium.....in the same group......... the the alkalinity of the barium oxide is slightly higher than the magnesium oxide.................
Which would you expect to have a higher melting point sodium chloride NaCI or aluminum oxide AI203?
The melting point of sodium chloride is 801 0C. The melting point of aluminium oxide is 2 072 0C.
What is the name of the white powder that is left when you burn magnesium?
the white powder is magnesium oxide. Magnesium burns in air with a dazzling white light to produce magnesium oxide. the equation is- 2Mg + O2 = 2MgO
Which substance sodium oxide or magnesium oxide has higher melting point?
sodium oxide: 1132oC magnesium oxide: 2852oC

What is the name of this compound Mg3 PO42?
i think its Magnesium phosphorus oxide.
What one has a higher mass percent of magnesium MgO or Mg3N2?
Magnesium nitride (Mg3N2) has a higher percentage composition of magnesium than magnesium oxide (MgO) does. The percentage composition of magnesium in magnesium nitride is 72.2% and the percentage composition of magnesium in magnesium oxide is 60.3%.
What is the common name for MgO?
Magnesium Oxide
Does calcium oxide have a higher lattice energy than magnesium oxide?
Cao or CaS have a higher lattice energy
What compound is magnesium and oxygen make?
This compound is magnesium oxide - MgO.
When you heat copper oxide and magnesium why do you get grey powder?
You get a grey powder because magnesium is higher up in the reactivity series than Copper - (magnesium is more reactive than copper) therefore when you heat it up there is a displacement reaction. That grey powder is actully magnesium oxide and copper e.g Copper oxide + magnesium = magnesium oxide and copper.
What does magnesium and copper oxide make?
Magnesium + copper oxide --> magnesium oxide + copper
What has the higher melting point sodium chloride or aluminum oxide?
aluminum oxide : Al2O3
What relationships are there between magnesium and magnesium oxide?
Magnesium is an element. Magnesium oxide is a compound formed from magnesium and oxygen. Magnesium oxide often serves as a magnesium supplement.
