Calcium oxide has a high melting point because it consists of ionic bonds between calcium and oxygen atoms, which are very strong and require a significant amount of energy to break. This gives calcium oxide a high melting point, as a large amount of energy is needed to overcome these strong bonds and transition from a solid to a liquid state.
Because ionic compounds have negative and positive charges known as cations and anions which are attracted ro each other therefore strengthening the bond within the lattice.
Calcium Oxide has a high melting point because it is an ionic compound.

Calcium oxide state?
Calcium oxide exists as a solid at room temperature and pressure. It is a white, crystalline compound with a high melting point.
Is Calcium Oxide a solid at room temperature?
Yes, calcium oxide is a solid at room temperature. It has a high melting point of 2,572 degrees Celsius, so it remains in a solid state at typical room temperatures.
Does the oxide of Barium have a high or low melting point?
Barium oxide has a high melting point of around 1,923 degrees Celsius. This is typical for many metal oxides, as they tend to have high melting points due to the strong ionic bonds between the metal and oxygen atoms.
Why does aluminum oxide have a high melting point?
Aluminum oxide has a high melting point because it has strong ionic bonds between aluminum and oxygen atoms. These bonds require a significant amount of energy to break, leading to a high melting point. Additionally, the structure of aluminum oxide is a giant ionic lattice, which further contributes to its high melting point.
Which property of calcium oxide does the lattice structure explain?
Oh, dude, the lattice structure of calcium oxide explains its high melting and boiling points. Like, the atoms are all arranged in a super organized way, making it harder for them to break apart when you try to heat them up. So yeah, if you're ever wondering why calcium oxide is so stubborn about turning into a liquid or gas, you can blame it on the lattice structure.

Is Calcium Oxide a solid at room temperature?
Yes, calcium oxide is a solid at room temperature. It has a high melting point of 2,572 degrees Celsius, so it remains in a solid state at typical room temperatures.
What phase is CaO?
Calcium oxide (CaO) is a solid at room temperature and is commonly known as quicklime. It has a high melting point of 2,572 degrees Celsius, indicating that it is in a solid phase under normal conditions.
Does the oxide of Barium have a high or low melting point?
Barium oxide has a high melting point of around 1,923 degrees Celsius. This is typical for many metal oxides, as they tend to have high melting points due to the strong ionic bonds between the metal and oxygen atoms.
Is calcium liquid at room temperature?
No it is a solid. Calcium has a high melting point. Most metals (except mercury) have high melting points.

What type of physical properties are in a calcium oxide?
Some physical properties of calcium oxide are:- density: 3,34 g/cm3- melting point: 2 613 oC- boiling point: 3 850 oC (at high pressure)- crystlline structure: face-centered cubic- enthalpy of formation: 635 kJ/mol
Of the following solids has the highest melting point H2Os Na2Os SO2s CO2s?
This element is wolfram (W): 3 422 oC.
Is calcium chloride soluble in water?
because it has high melting/dissolving point.
What can you say about the melting points of the oxides of zinc oxide?
The melting point of zinc oxide is relatively high, around 1975°C. This is because zinc oxide forms a network crystal structure with strong ionic bonds between zinc and oxygen atoms. The high melting point reflects the energy required to break these bonds and transition from a solid to a liquid state.
