What else can I help you with?
Is most metals reactive.?
Most metals are reactive to some extent, but their reactivity varies. Some metals, such as gold and platinum, are less reactive and do not easily tarnish or corrode. Other metals, like sodium and potassium, are highly reactive and must be stored in oil to prevent them from reacting with moisture in the air.
Is a cation metal or nonmetal?
A cation is typically formed from a metal atom by losing one or more electrons, so it is generally associated with metals. Metals tend to easily lose electrons, forming positive ions (cations).
What describes the alkaline metals?
The alkaline metals group is the group at the very left group on the periodic table. The elements in this group have only 1 electron in the outer shell, so they react very easily, with for instance water.
The most active metal would be the one that is?
largest
Are non-metals flexible?
No, non-metals are not malleable simply because of the way the atoms are arranged. In metals the atoms are arranged so they will just slide past each other but in non-metals the atoms are arranged differently so they on't just slide past each other.
Why are the metals in the first group of the period table so reactive?
These metals lose easily an electron.
A metal that can be pounded into a shape?
One example of a metal that can be easily pounded into a shape is copper. Copper is malleable, which means it can be hammered or pressed into various forms without breaking or cracking. This property makes copper a popular choice for creating intricate designs in artwork and jewelry.
How can solid change its shape?
You could easily melt it.Or sublimate it.--------------------------------------------------------------------------------------------------------------A:Melting and sublimation change the physical state so you no longer have a solid.Solids can be bent, stretched, and flattened.Ductility and malleability are the properties in which metals can be formed.All materials also have thermal expansion properties. Usually this doesn't affect the overall shape significantly, but it could cause items that fit tightly to become loose. If two metals with different thermal expansion properties are annealed together, they can bend when heated, and return to the original shape when cooled. Thermostats may use this property.Certainly if you think of the rubber in a balloon being a solid, then its shape is dependent on the pressure of the gasses inside and outside of it.
Why do metals form cation?
metals have high electropositivity and low ionisation energy. So they tend to form cations easily.
What does it mean when a liquid has a definite volume but no definite shape?
It means that the liquid takes the shape of its container, but its volume remains constant. This property is characteristic of liquids, where the particles are able to flow and move easily but do not expand to fill the entire space of the container.
A certain substance a cannot be compressed but takes up the shape of any container in which it is placedwhat can be its physical state?
The substance is likely a liquid. Liquids have definite volume but no definite shape and take the shape of their container. Additionally, liquids are generally considered incompressible compared to gases.
What is the appearance of group 1 metals?
High luster, reacts with air on contact so must be stored under kerosene, Soft metals that can easily be cut with a knife.
Why can't we cut liquid and gas?
We can't cut liquids and gases because they don't have a fixed shape like solids. Liquids and gases can flow and change shape easily, so trying to cut them would simply cause them to move and change form rather than being cleanly separated.
Why do cations form?
metals have high electropositivity and low ionisation energy. So they tend to form cations easily.
Why is alkali metal different to other metals?
because it has so many orbitals it has more electrons and it cannot hold onto its electrons as easily and they can easily be snatched away
Why were pencils cut into hexagonal shape?
Pencils are cut into a hexagonal shape for a variety of reasons. One reason is so that the pencil does not roll off a flat surface, such as a desk, quite so easily. Another reason for being cut hexagonally is so that they can stack more easily.
Why are transition metals not as reactive as alkali metals and alkali earth metals?
transition elements are not as reactive as alkali metals or alkaline earth metals.. this is so because of the valence electronic configurations. alkali metals have ns1 configurations which have easy chances of loosing electrons so as to gain the stable state. Attaining a stable state is the law of nature. hence to attain it they have to redily donate electron. this is not so easily possible for the transition elements..
