Alkali metals can be cut with a knife because they are soft and have low melting points. Iron cannot be cut easily with a knife because it is a strong and hard metal. The differences in properties between alkali metals and iron make alkali metals easier to cut with a knife.
Boron's family has no specific name like the Halogens or the Alkali metals. It is simply the Boron Family.
In the old numbering system, "A" simply refered to the the left side of the table. Group IA,IA are alkali metals.
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.
You would call them pure metals or simply elements, when a metal is mixed with another, usually for dual properties (e.g steel and aluminum alloy - in planes because it is light and strong) it is called an Alloy.
It does not belong to any; it is simply a nonmetal.
Group 1A elements are active metals. They are so active that they are never found free in nature. They are usually stored in oil. They form compounds with oxygen that dissolve in water to give solutions that are alkaline or caustic. They are called alkali metals, or simply the alkalis.
Not necessarily. Non-ferrous simply means not iron. The term may be used to refer to metals that are unlike iron, but there are very many of them which are not alkali either.
Boron's family has no specific name like the Halogens or the Alkali metals. It is simply the Boron Family.
No, because it is not real. One cannot simply walk into Mordor. The evil is much too great there.
because it simply cannot be expressed as a fraction (I think that this is right)
You cannot answer such a question. It's located where it is simply because that's its placement.
no it doesn't, it simply just turns it into an indicator and has not neutralised it.
Simply because - sound cannot travel in the vacuum of space.
Most metals are characterized by freely exchanging electrons among the separate atoms that make up a piece of the metal. This is why they look shiny. Because electricity is simply electrons in motion, electricity travels readily through metals.
Simply because 967 people have chosen to live there. It cannot be explained.
Simply because it doesn't divide by 2 exactly, and therefore cannot be even !
They are highly reactive metals, reacting with water (explosively) and air. In nature they simply would not last very long at all! i don't know. but i am in chemestry and i need to know. what i know so far is, that the are found in common substances. if you are a chemestry teacher you should know! :) plese get back to me by december 13th. i have a short exam then. but i also know that They are unstable in air and in water (moisture).
