Why some elements have positive valency and others negative?
it depends if negitive dont put it with a positive
Radical - positive and negative radical in chemistry?
Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent
What is a negative - positive?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Why silicon has valency 4 and chlorine has 1?
I want answer
When multiplying numbers what do you do with the positive and negative signs?
Negative * positive = negative Positive * positive = positive Negative * negative = positive
Does chlorine form positive or negative ions?
Chlorine forms a negative ion.

Does chlorine form a positive or a negative ion?
Negative ion. Cl-
Would chlorine fom a positive or a negative ion?
Chlorine will form a negative ion with a charge of -1 because it gains one electron to complete its octet.
Is arsenic positive negative or neutral?
Arsenic atoms are neutral and they form ions with valency of three.
Does a chlorine ion have a negative or positive charge?
Non it is neutral
Which would form a negative ion lithium aluminum magnesium or chlorine?
Chlorine would form a negative ion and the other three positive ions.
Why does Hydrogen Chloride not conduct electricity when dissolved in hexane but conducts electicity when dissolved in water?
Water is a polar molecule and hexane is non-polar. This means that water has positive charges that grab on to the negative-chlorine and water has negative charges that grab onto the positive-hydrogen. This pulls the hydrogen and chlorine apart as positive and negative ions. The these positive and negative ions can move around separately as positive and negative electrical carriers. In hexane the hydrogen and chlorine are locked together, a single neutral molecule and no charged ions. Any positive movement of the hydrogen is locked to the negative movement of the chlorine, so any movement balances out to zero charge movement and zero electrical movement.

What is the valency of barium chloride ion?
Barium's charge is 2+ and Chlorine's charge is 1- so the formula would be BaCl2
Does Chlorine have a negative or positive charge?
generally negatively charged chloride ion. but there are a few species where chlorine has positive charge like ClO3-, ClO4- etc.
