What have high melting and boiling points?
metals
All metals are hard and have high melting points?
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.
What do metalls have in common?
Metals with very high melting points are useful
Do group one metals have a high melting point?
No. Group 1 metals (commonly called the alkali metals) have low melting points.
Generally melting points of metals are high name two metals whose melting points are so low that they would melteven when kept in hand?
Galium n Mercury
Do have nonmetals have high melting points?
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.
Why all crystals have high melting points?
because all crystals are metals .
Does a metal have a high or low melting point?
All metals have different melting points but they are all high
Is calcium liquid at room temperature?
No it is a solid. Calcium has a high melting point. Most metals (except mercury) have high melting points.
How are the melting points of salts similar to that of metals?
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.
Do metalloids have high melting points?
Metalloids have melting points that are generally lower than those of metals but higher than those of nonmetals. Their melting points can vary depending on the specific element and its atomic structure.
True of false all metals are hard and have high melting points?
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.
