How do non metals form negative ions?
They gain the few electrons they need to form full octets
What is a substance that has lost or gained electrons?
Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.
Do noble gases react with metals and non metals?
Nobles gasses will not react with metals or most nonmetals. Only a few noble gasses compounds exits, and none exist naturally. Noble gasses will only form compounds with fluorine and oxygen.
Is magnetism a common property of metals?
No. Only a few metals can be made magnetic
Are elements with very few valence electrons mostly non-metals?
No, they are metals.
What metals have few and form positive ions?
tehey have few electrons
What ions do transitional metals form?
All metals, whether they belong to the transition state or not, will form only positive ions. There are a few metals which are extremely hard to ionize, however, those being the noble metals such as gold and platinum. But if you do manage to ionize them, the ions are positive.
Why do metals tend to lose electrons form positive ions?
Metals tend to lose electrons to form positive ions because, for metals to gain a full outer shell, they need to lose electrons.
Chloride soluble or insoluble in water?
In solid, a chloride ion is bound with a singly-charged positive ion (or two chloride ions with a doubly-charged positive ion). Examples are NaCl, CaCl2, etc. When these salts are added in water, the +ve ions and -ve ions are separated -- the salt dissolves in water and the clear solution can be colorless (e.g. NaCl) or colored (e.g. CuCl2), depends on the type of positive ion. A few chloride ions exist in air, but will not last too long, because negative ions will be attracted to positive ions in air to form solid (like dust).
Why do metals tend to lose electrons to form postivtive ions?
Metals tend to form positive ions because their electron structure causes them to do so. We need to talk briefly about what this means, so put on your thinking cap and grab a seat. We know that electrons form up around atoms in shells (energy levels). And only a certain number of electrons can occupy a given shell. Further, atoms tend to want to have outer electron shells that are filled to capacity, just like the inert or noble gases. To that end, atoms will loan out or borrow electrons, and this is the basis for chemical bonding. Metals are atoms that have incomplete outer electron (valence) shells. But they are also atoms that have a lot fewer electrons in their outer shell than it takes to actually fill that shell. (This is in contrast to the nonmetals, which have outer electron shells that are nearly full.) Because metals have "so few" electrons in their valence shells compared to what it would take to fill them, it is "easier" for these atoms to loan out electrons rather than borrow electrons to reach a point where they are emulating an inert element. Because metals loan out electrons to reach a point where they are "like" inert gases, they will end up as positive ions. And this is why metals form positive ions.
Why mercury is considered as metal as they are bad conductor of heat and electricity?
What are you trying to ask? Your question contains such poor grammar and sentence structure as to be practically indeciferable. First: Mercury is a very good conductor of both heat and electricity. Second: Metals are good conductors. Metals also have LUSTER. They are shiny. Mercury has luster. Metals have few (1 to 3) outer energy level electrons. Mercury has this as well. In reactions, metals tend to lose the outer electrons and form positive ions. Again mercury has this property.

What are the similarities and differences between metals and non metals?
Metals: -Malleable. -Shiny -ductile -good conductor of electricity and heat. -other than mercury, all metals are solid at room temp. -not brittle. -melts at high temp. except mercury Non-metals: -non-malleable -not shiny -not ductile -poor conductor of electricity and heat -at room temp., most are gases. -melts at low temperature.

Why are metals found underground?
Not all metals are found underground- a few can be found at the surface. However, metals are usually not fund in a pure form, but are mixed with impurities in the form of ore, which was distributed vertically and horizontally as that rock strata was formed.
Why do some atoms form positive ions and others form negative ions?
It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
Why there is no formation of ions in case of carbon?
generally carbon forms covalent bonds. there are a few exceptions when carbides are formed in reaction with metals when ions such as (C2)2- (sorry the edit function is rubbish at the momnt and the superscript subscript functions are not working. )
