every metal has different atoms
so depending upon the nature of the atom there is different type of bonding of different strength is among the atom
now melting point of a substance depends upon strength of these bonds so every metal has different melting point
Metals have high melting and boiling points because in metals there is a very strong intermolecular force of attraction and it needs a lot of energy to melt or to boil
The question needs to be refined: which metal(s) [Mercury is a liquid at room temperature], and compared to what other element(s) or compound(s) [common table salt requires temperatures comparable to the surface of the sun to melt] are items that need to be specified!
they have height melting and boiling points because their structure is in the "lattice" formation, which gives them flexibility (in general) but the intermolecular forces binding them together are strong, as they are densely packed together
There is NO IONIC BONDING in metals. It is metallic bonding, which is something totally different.
Metallic bonding involves a "sea of electrons" delocalised in a vast array of molecular orbitals that extend over the metal atoms. There are strong forces of attraction between these delocalised electrons and the positive nuclei of the atoms, which are relatively difficult to overcome and thus explain the high melting and boiling points of metals.
The link below has a good explanation.
Source(s):http://www.chemguide.co.UK/atoms/bondingDifferent elements have different chemical properties because they have different atomic structures and characteristics.
Different chemical elements have different atomic structures, and particularly different electron shell structures. Chemical bonding is generally based on electron structures of atoms, and as these structures vary (or are similar) so the chemical properties vary (or are similar).
Different elements have different chemical properties because they have different atomic structures and characteristics.
Due to the different density of objects there will be a variety of melting points
it takes longer for the atoms to get alot of energy
this is because each metal is unique and shares some property
Yes
The melting points of metals would depend on the metal itself- different metals have different melting points. A website is available under "related link" which contains information about the melting points of different metals.
According to RAOULT, when two different metals of different melting points are melted or alloyed there melting points considerably change. So,according to the percentage of impurities, the melting points either increase or decrease.
Alkali Metals
There is no common melting point, it will vary a lot with the type of metal.
Most metals do indeed have high melting points . The simple explanation is that the metallic bonds in these metals are very strong. There are low melting metals, the lowest mp metals are mercury a liquid at room temperature, gallium that melting at around 300C.

Alkali metals have relatively low melting points compared to the other metals. Their exact melting points depend on the element itself. But it would be useful to note that their melting points decreases down group I.
No, the alkali metals are pretty soft and the metals cesium, gallium, and mercury have very low melting points.
Each material has specific melting point; and an alloy is not a single element.
sodium
metals
No. Group 1 metals (commonly called the alkali metals) have low melting points.
All metals have different melting points but they are all high
Alkali Metals
Yes.
Different proteins have different melting points.
