Why do compounds conduct electricity when in water?
Compounds conduct electricity when in water because water is a polar solvent that can dissociate ionic compounds into ions. These free ions can carry electrical charge and allow for the flow of electricity through the solution. Covalent compounds may also conduct electricity in water if they ionize or undergo chemical reactions that create mobile charges.
What type of bonding is associated with compounds that have the following characteristics?
Ionic bonding is associated with compounds that have high melting and boiling points, are soluble in water, and conduct electricity in molten or aqueous state. Ionic compounds are formed by the transfer of electrons from a metal to a nonmetal.
When a metal reacts with a nonmetal are the substances good conductors of electric current?
It depends on the nature of the metal-nonmetal compound formed. Metal-nonmetal compounds, known as ionic compounds, are usually poor conductors of electric current in solid state due to the lack of free-moving electrons. However, when dissolved in water or melted, they can conduct electricity due to the presence of mobile ions.
Why does lithium metal conduct electricity well where as sold lithium chloride does not?
Lithium chloride is a completely different substance than lithium metal. Sodium chloride is table salt however table salt isn't highly corrosive or explosive in water. Properties can change dramatically when compounds are formed.
What is polyalkene?
it is watretight and doesnt conduct heat or electricity ie fairly unreactive
Can covalent compounds conduct electricity in water?
Generally, molecular covalent substances do not conduct electricity. Carbon as graphite is the exception. This is because they are neutrally charged; they do not have ions or delocalized electrons as these are being shared by the non-metals. Yet some conduct electricity when dissolved in water. This is because some react with water to produce ions which are attracted to the oppositely charged electrodes.

Give the properties of ionic compounds?
Ionic compounds are typically formed between a metal and a nonmetal. They have high melting and boiling points, are soluble in water, and conduct electricity when dissolved in water or as a molten state due to the presence of free ions. Additionally, they tend to have a crystalline structure and are usually hard and brittle.

When ions are formed in water the solution has the ability to conduct what?
electricity
What are the characteristics of ionic compounds vs molecular compounds?
Ionic compounds are formed by the transfer of electrons between atoms to create ions, resulting in a lattice structure with strong electrostatic forces between oppositely charged ions. Molecular compounds, on the other hand, are formed by the sharing of electrons between atoms to create covalent bonds, resulting in discrete molecules held together by weaker forces. Ionic compounds typically have higher melting and boiling points, are usually soluble in water, and conduct electricity in molten or aqueous solutions due to the presence of free ions. Molecular compounds tend to have lower melting and boiling points, are often insoluble in water, and do not conduct electricity.
What are the properties of a covalent compounds?
Covalent compounds are formed when atoms share electrons to achieve a full outer shell. They typically have lower melting and boiling points compared to ionic compounds, and are often gases, liquids, or soft solids at room temperature. Covalent compounds do not conduct electricity in their pure form.
Can you list properties of ionic compounds?
Ionic compounds are formed by the attraction between positively and negatively charged ions. They have high melting and boiling points. Ionic compounds are usually solid at room temperature. They conduct electricity when dissolved in water or melted.
What are the properties of ionic and molecular compounds?
Ionic compounds are between metals and non-metals. Molecular (covalent) compounds are between only non-metals. (Metallic compounds are between metals and other metals) An ionic compound is a pure substance that is formed from a metal and a nonmetal. It has a fairly high melting point and is a conductor of electricity when in a molten or aqueous state. A molecular compound, on the other hand, is a pure substance that is formed from nonmetals. It has a fairly low melting point, and can only conduct electricity unless it is aqueous and polar. Another important difference between the two is that an ionic compound is a crystalline solid at standard temperature and pressure (STP), whereas a molecular compound can be in a solid, gas or liquid state at STP.
What are the characteristic of most ionic compounds?
High boiling/melting points. Very hard. They can conduct electricity when molten or dissolved. EXPLANATION: High boiling/melting points - they form lattices held together by electrostatic forces of attraction which stretches not only to the atom they reacted with but to all the ions in the lattice, which makes it hard to break. Very hard - lattice is a regular structure. Also see above. They can conduct electricity when molten or dissolved - the ions are positively and negatively charged but stuck in fixed positions when a solid. When molten or dissolved, the ions are free to move around and therefore carry the charge so conduct electricity.
Why does an aqueous solution conduct electricity?
An aqueous solution conducts electricity because it contains both positive and negative ions that can move freely in the solution, allowing for the flow of electric current. The ions are formed when ionic compounds dissociate in water, creating a conductive medium for the movement of charged particles.
What are two major characteristics of molecular compounds?
Low melting and boiling points. Some are polar and some are nonpolar. Those that are polar will dissolve in water. They also do not conduct electricity.
