Metals are strong and dense because of the size of the nuclei within the atom. These nuclei have a strong electrostatic force, pulling the electrons that circle them closer. When you get a group of the atoms, they form what is known as a lattice structure, this structure is made from all the atoms bonding together within the solid metal. When this structure is formed, it is very small with allot of atoms inside it due to the strong electrostatic force, making the lattice structure more compact and thus, making it denser and stronger.
It might not have made allot of sense but it can give you th rough outline of what I was trying to say :)
Even if metals can be less dense than the sugar, metals are solid and not of powder
Generally metals are hard, dense, with good thermal and electrical conductivity, can form cations, many are malleable or ductiles, etc.
the atoms are very tightly packed together as there are strong forces of attraction
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.
Gold, platinum. Tin and lead are also quite dense. Osmium is the most dense on the periodic table.
As metals lose Heat (Thermal Energy), they become more Dense. They also become more Brittle, and prone to shatter on strong impact!
Alkali metals are very reactive, not dense or hard metals, monovalent, with low electronegativities, with low melting and boiling points, react violently with water, form strong bases, etc.
Metals like steel are strong in room temperature. If you want anymore, search for metals as strong as steel :)
on metals are brittle. They are less dense and non sonorous
Even if metals can be less dense than the sugar, metals are solid and not of powder
Many metals are lustrous, hard, dense.
Even if metals can be less dense than the sugar, metals are solid and not of powder
Potassium and Lithium
Strong (i.e. bread grade) wholemeal flour is the most dense.
Osmium and gold are more dense than mercury.See the Related Questions for a complete list of the most dense elements (many of which are more dense than mercury).
not sure
Yes, there are at least two: Iodine vapor (molar mass 254) and Radon gas (222, but not natural occurring) are heavier (and so more dense) than Mercury vapor (200 g/mol).
