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.
no
No. Group 1 metals (commonly called the alkali metals) have low melting points.
The melting points of salts and metals are both influenced by the strength of the bonds holding their atoms or ions together. In salts, ionic bonds between cations and anions result in high melting points due to strong electrostatic forces. Similarly, metals exhibit high melting points due to metallic bonds, where electrons are shared among a lattice of positively charged ions. Thus, both salts and metals typically have elevated melting points compared to molecular compounds, reflecting the strength of the interactions within their structures.

no
Metals have high melting points. Metals lack ionic bonding and possess metallic bonds that are so strong that it takes so much heat to break them apart.
Yes non metals do have high melting and boiling points. This is because they have strong intemolecular forces that are hard to overcome.A2. Their melting points vary. Obviously gases such as nitrogen and oxygen have low melting points, but Silicon (1414oC) and Diamond ( around 1700oC) are rather high. Phosphorous and Sulfur on the other hand are rather low.
Metals with very high melting points are useful
No. Group 1 metals (commonly called the alkali metals) have low melting points.
Galium n Mercury
Metals are often hard. They conduct both heat and electricity. They often have high densities, high melting points, and high boiling points. And always loose electrons when bonding. Non-metals are the opposite of all the above characteristics.
because all crystals are metals .
All metals have different melting points but they are all high
