The answer is "No ". Mercury is a liquid (at normal temperatures and pressures) Sodium is a solid, but is quite soft and can be cut with a pen-knife. It is highly reactive and bursts into flame (i.e. it oxidises) on contact with the air.
I should say Farley strong well not hard as a rock some types of metal are bendable but it depends on what metal your talking about
No, I can only think of one example, sodium (not salt because salt is sodium chloride) is clay like metal that also bursts into flames and explodes when it comes into contact with water.
This affirmation is not generally valid.
because its a solid
yes
No, the alkali metals are pretty soft and the metals cesium, gallium, and mercury have very low melting points.
no
No. Group 1 metals (commonly called the alkali metals) have low melting points.
It varies on which metalloid you are talking about but in general they have low melting points
Transition metals tend to have very high melting points.
No, the alkali metals are pretty soft and the metals cesium, gallium, and mercury have very low melting points.
metals
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.
No. Group 1 metals (commonly called the alkali metals) have low 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.
Metals with very high melting points are useful
Pure metals have high density and very high melting and boiling points. In addition, these metals are excellent conductors of heat and electricity.
Galium n Mercury
because all crystals are metals .
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.
All metals have different melting points but they are all high
