because they are ionic compounds and have strong electrostatic force of attaction
Because they have interlocking electrons as the different elements' electrons have been 'tangled'
Not all metals are hard, as some metals like gold and lead are relatively soft. Additionally, while many metals have high melting points, some metals like mercury have low melting points. The properties of metals can vary widely depending on the specific metal in question.
False. While many metals are hard and have high melting points, not all metals exhibit these properties. For example, metals such as mercury and gallium have low melting points and are liquid at room temperature. Additionally, some metals can be relatively soft, such as gold and lead.
Melting points vary with pressure. In nearly all substances the melting point increases with increasing pressure. The peridotite in the mantle is extremely hot and under immense pressure. When it is decompressed some melting occurs. The composition is not uniform and some minerals have lower melting points than others. The mafic minerals will be able to melt while the ultramafic mineralls generally will not.
Which metal needs to be specified. Look in a Chemistry book or reference book. All metals have their own melting and boiling points - that's one of the ways we identify which metal the item is made of.
False, all minerals DO NOT have the same melting point
All metals have different melting points but they are all high
because all crystals are metals .
No, minerals have different melting points depending on their chemical composition and structure. The melting point of a mineral is influenced by factors such as the type of bonding between atoms, presence of impurities, and pressure conditions.
At 6000K all elements will turn into a gas.there could be hundreds of unknown elements in space so there could be even higher melting points

No, all metals melt. Though some have extremely high melting points.
yes all metals melt but at differenttemperatures some have low and some have high melting points
Yes, all metals have definite melting points. Most, under earths atmospheric pressure, have very high (hot) melting points, but mercury is liquid at room temperature. Mercury begins to "melt" from it's solid form at 39 degrees below zero!
Covalent structures have high melting points because the covalent bonds between atoms are strong and require a significant amount of energy to break. This high energy barrier results in a high melting point for covalent structures.
No, not all rocks can be melted. Rocks with high melting points, such as granite, can require very high temperatures to melt. Additionally, some rocks can react chemically or decompose before reaching their melting point.
