# data[].attributes.body
Because metals have molecules which are held together by strong molecular forces which make it closely packed together (high density) and require a lot of energy to break the forces and change its state (melting and boiling point)

# data[].attributes.body
Metals have high densities, melting points, and boiling points because the particles are bound together by very strong forces of attraction. These particles form giant lattice structures, which means that it requires large amounts of energy so that the bonds can be broken.

# data[].attributes.body
Metals are able to conduct heat because the free moving electrons can carry the heat energy around easily from one part to another.

# data[].attributes.body
Metals conduct electricity beacuse they have freely moving electrons. When they receive the electricity, the electrons will carry and spread it through the metal

# data[].attributes.body
Because metals have delocalized electrons which allow the layers of metals to slide over one another without breaking apart, making it malleable and ductile

# data[].attributes.body
Metals have atoms that can overlap and roll over each-other without breaking the bonds. The layers of these atoms are still held together by electrons.

# data[].attributes.body
Metals conduct electricity because the electrons inside the metal are relatively free to move

# data[].attributes.body
The metal layers can slide around one another but are still held together by the free moving electrons

# data[].attributes.body
Because metals have giant lattice structures with very strong bonds. High heat and energy is very much needed to break those bonds. This is also caused by the high densities they have due to the amount of atoms inside the metals.

# data[].attributes.body
Metals are able to conduct electricity because the metals have free electrons. This means when an electronic charge passes through the metal, these free electrons pass it through and spreads it across the metal, making metal conductive.

# data[].attributes.body
Because they have electrons which are free to move, therefore when they receive electricity, they will carry and spread it to other electrons, therefore conducting it

# data[].attributes.body
The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points.

# data[].attributes.body
Metals have high melting and boiling temperatures because they have massive lattice structures and require a huge number of electrostatic forces.

# data[].attributes.body
Because metals have free electrons, so that when heat is applied to it, it will vibrate and spread to the other electrons (conduction), therefore conducting heat

# data[].attributes.body
Metals have particles that vibrate which can spread heat around the metal easier. These free moving electrons allow the metal to be a good conductor of heat.

# data[].attributes.body
Metals have high densities because their atoms are closely packed and due to the strong metallic bonding in their giant lattice structure, a large amount of energy is required to break the bonds making their melting and boiling points high.

# data[].attributes.body
Because the metal's layers on ions can slide over each other but still can be held together by the electrons.

# data[].attributes.body
The electrons in them can move around easily, and they can carry heat from one part to another.

# data[].attributes.body
The electrons in metals can will absorb the heat and carry it from one part to another, through vibration. Since metal atoms are packed closely to each other, which makes heat transfer faster.

# data[].attributes.body
Metal have giant lattice structures and due to this requires large amounts of energy to be broken, meaning it requires a ton of heat to supply the large amount of energy needed.

# data[].attributes.body
some metals dont really have high density but most metals do have it because of the tightly packed crystal lattice of the metallic structure due to the metallic bonding

# data[].attributes.body
the ability of the atoms to roll over each other into new positions without breaking the metallic bond.

# data[].attributes.body
Metals can conduct electricity because the electron carries the electricity and can move from one part to another because electrons can spread it all over the metal.

# data[].attributes.body
the electrons inside the metal are relatively free to move

# data[].attributes.body
Because the electrons inside the metals have moves freely. Making any electrical activity pass through the metals/get conducted.

# data[].attributes.body
the electrons in them can move around easily, and they can carry heat from one part to another

# data[].attributes.body
The structure of most metals is they have repeating layer of atoms which can slide over each other but still retain their structure because it is held by delocalised electrons.

# data[].attributes.body
the electrons in them can move around easily, and they can carry heat from one part to another.

# data[].attributes.body
Because the particles in a metal are very closely packed together and will transfer the strong vibrations caused by the energy of the heat.

# data[].attributes.body
Metals can be hammered into various shapes because they are malleable. Their structure, in which we find layers of cations that can slide over one another, explains this. Repulsions between the cations are avoided by the rapidly delocalized electrons.

# data[].attributes.body
because the electrons inside the metal are relatively free to move. So when electricity is pass through metals, electrons carry electricity and spread it all over the metal.

# data[].attributes.body
Metal's layers of ions can slide over each other, but are still held together by the delocalised electrons and it means that metals are malleable because it can be hammered into shapes and ductile because it can be drawn out into wires
