A metal is a chemical element that is a good conductor of both electricity and heat and forms cations and ionic bonds with non-metals. Cations are usually formed by electron loss.

How do solid nonmetals differ from solid metals?
Solid nonmetals typically have lower melting points and boiling points compared to solid metals. Nonmetals tend to be brittle in their solid state, while metals are malleable and ductile. Additionally, nonmetals are usually poor conductors of heat and electricity, whereas metals are good conductors.
How does justifiable conduct differ from excusable conduct?
Justifiable conduct means the action was warranted or reasonable given the circumstances, such as self-defense. Excusable conduct refers to actions that are considered wrong but are forgiven due to circumstances like being a minor or mentally ill. In essence, justifiable conduct is seen as acceptable, whereas excusable conduct is viewed as wrong but understandable.
Are the trends for melting point and boiling point the same as nonmetals and explain?
No, the trends for melting points and boiling points in nonmetals are generally different from those in metals. Nonmetals typically have lower melting and boiling points compared to metals, which tend to have high melting and boiling points due to strong metallic bonds. In nonmetals, the melting and boiling points can vary significantly based on molecular structure and intermolecular forces, with noble gases having very low points and some covalent network solids like diamond having high points. Therefore, while both groups exhibit trends, the underlying reasons and values differ significantly.
How are metals and semimetals alike and different?
Metals and semimetals are alike in that they both have high electrical conductivity. They differ in that metals are typically solid at room temperature, while semimetals can exist in both solid and semi-solid forms. Additionally, semimetals have properties that are intermediate between metals and nonmetals.
How do non metals vary from metals?
Metals1 they allow electricity and heat to pass through them easily2 they are all solids in room temperatures exept for mercury , and most of them have high melting points.3 nost of them can be hammed into different shapesnon metals1 they are poor conductorsof electriity and heat2 they usually have low melting points3 when solid non-metals are hammed, they break up-they are brittle.
How does the polarization of insulators and conductors differ in terms of their ability to conduct electricity?
Insulators have tightly bound electrons and do not conduct electricity well, while conductors have loosely bound electrons that can move freely and conduct electricity effectively.
What are metals on the periodic table and how do their properties differ from nonmetals and metalloids?
Metals on the periodic table are elements that are typically shiny, malleable, and good conductors of heat and electricity. Their properties differ from nonmetals and metalloids in that metals tend to be more ductile, have higher melting and boiling points, and are more reactive. Nonmetals, on the other hand, are typically brittle, poor conductors of heat and electricity, and have lower melting and boiling points. Metalloids have properties that are intermediate between metals and nonmetals.
How do ionic bonds differ from covalentbonds?
Ionic bonds are formed between ions with opposite charges, one giving away electrons and the other accepting them, resulting in the formation of a bond. Covalent bonds involve the sharing of electrons between atoms to complete their valence shells. Ionic bonds are typically formed between metals and nonmetals, while covalent bonds are formed between nonmetals.
How does the formation of an ionic bond differ form the formation of a covalent bond?
In an ionic bond, electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that are attracted to each other. In a covalent bond, electrons are shared between atoms to achieve a stable electron configuration. Ionic bonds are typically formed between metals and nonmetals, while covalent bonds are formed between nonmetals.
How does a triac differ from SCR?
An SCR is a rectifier and can only conduct in one direction (half wave).A Triac can conduct in both directions (full wave).
How do ionic bonds differ from covalent bonds-?
Ionic bonds involve the transfer of electrons from one atom to another, resulting in the formation of ions that are attracted to each other due to opposite charges. Covalent bonds involve the sharing of electrons between atoms, creating a strong bond due to the shared electrons. Ionic bonds typically occur between metals and nonmetals, while covalent bonds usually occur between nonmetals.
How do metals differ from nonmetals?
Metals usually have characteristic(s) of at least one of the following: luster, shine, malleable, ductile, and conducts electricity. Non metals don't conduct electricity and are usually brittle.
How do solid nonmetals differ from solid metals?
Solid nonmetals typically have lower melting points and boiling points compared to solid metals. Nonmetals tend to be brittle in their solid state, while metals are malleable and ductile. Additionally, nonmetals are usually poor conductors of heat and electricity, whereas metals are good conductors.
What is the main reason why race horses differ in ability?

How do he seasons differ between the uae and USA?
How do he seasons differ between the uae and USa?
What is the relationship between the speed of light in a medium, characterized by the parameters mu and epsilon, and how does it differ from the speed of light in a vacuum?
The speed of light in a medium is determined by its parameters mu and epsilon, which represent the medium's ability to conduct and store electric and magnetic fields. This speed is slower than the speed of light in a vacuum because the medium affects the propagation of light waves.
What covalent bonds are most polar?
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
