When an atom loses an electron, it loses a negative charge and becomes a positive ion. When an atom gains an electron, it gains a negative charge and becomes a negative ion. Ionic bonds form as a result of the attraction between positive and negative ions. When ionic compounds form, the ions come together in a way that balances out the charges on the ions. The chemical formula for the compound reflects this balance. For an ionic compound, the name of the positive ion comes first, followed by the name of the negative ion. In general, ionic compounds are hard, brittle crystals that have high melting points. When dissolved in water or melted, they conduct electricity.

What formula dissolves in water to form an ionic solution?
Ionic compounds, such as sodium chloride (NaCl) or potassium nitrate (KNO3), dissolve in water to form an ionic solution. When these compounds are added to water, they dissociate into ions, which allows them to conduct electricity and exhibit other characteristic properties of ions in solution.
Are acids ionic compounds?
Acids are not typically considered ionic compounds. Acids are usually covalent compounds that contain hydrogen ions. When acids dissolve in water, they release hydrogen ions (H+) and form hydronium ions (H3O+), which gives them their characteristic acidic properties.
Are orderly crystal shapes high melting points and electrical conductivity when dissolved in water properties of ionic compounds?
Yes, orderly crystal shapes and high melting points are properties of ionic compounds due to the strong electrostatic forces between the positively and negatively charged ions. However, ionic compounds do not conduct electricity when dissolved in water because the ions are already separated.
Most compounds that produce this in aqueous solution are ionic?
Most compounds that produce an electrolyte in aqueous solution are ionic. When dissolved in water, ionic compounds such as salts dissociate into their constituent ions, increasing the solution's conductivity, which allows it to conduct electricity. This is why most electrolytes in aqueous solution are ionic compounds.
What statement best describes the properties of ionic compounds?
Ionic compounds are composed of cations (positively charged ions) and anions (negatively charged ions) held together by electrostatic forces. They tend to have high melting and boiling points due to strong ionic bonds. These compounds are often soluble in water and can conduct electricity when dissolved or melted.
Which characteristic of ionic bonds can be used to explain the properties of ionic compounds?
the properties of an ionic compound can be explained by ht e strong attractions among ions within a crystal lattice.
What has positive ions and can form ionic compounds?
Metals form positive ions and form ionic compounds with negative ions.
What formula dissolves in water to form an ionic solution?

What is the conclusion of the properties of ionic and covalent compounds?
Ionic compounds result from the transfer of electrons between atoms leading to the formation of ions, while covalent compounds form from the sharing of electrons. Ionic compounds tend to have higher melting and boiling points compared to covalent compounds due to the stronger electrostatic forces between ions.
Are orderly crystal shapes high melting points and electrical conductivity when dissolved in water properties of ionic compounds?
Yes, orderly crystal shapes and high melting points are properties of ionic compounds due to the strong electrostatic forces between the positively and negatively charged ions. However, ionic compounds do not conduct electricity when dissolved in water because the ions are already separated.

What are three general properties of ionic compounds?
Ionic compounds have high melting and boiling points due to strong electrostatic forces between ions. They are usually soluble in water due to the polar nature of water molecules and the ability of water to surround and separate the ions. Ionic compounds conduct electricity when dissolved in water or when melted, as their ions are free to move and carry electric charge.
What 3 properties may be used to identify ionic compounds?
Three properties that may be used to identify ionic compounds are: Solubility in water: Ionic compounds tend to dissolve in water due to their ability to ionize and form charged species. Conductivity: Ionic compounds in solution can conduct electricity due to the presence of free ions that can carry charge. High melting and boiling points: Ionic compounds have strong electrostatic forces holding the ions together, resulting in high melting and boiling points.
Does ionic compounds make molecules or ions?
Ionic compounds typically form ions when dissolved in water or melted, as the strong electrostatic forces between the positively and negatively charged ions prevent them from forming discrete molecules. In the solid state, ionic compounds exist as a lattice of alternating cations and anions held together by ionic bonds.
