The number represents the charge on the ion. The number is the quantity of electrons lost or gained by the elemental atom to become an ion. Thus gaining 1 electron makes the ion -1, because the electron is negatively charged. Losing an electron results in a positively charged ion +1. So if two electrons are gained the charge is -2. These numbers are also called oxidation numbers, representing the oxidation state of the element as the ion.

The PLUS sign indicates a positive charge.
These are called protons.

Explain how a water molecule can be attracted to both a positive ion and a negative ion when dissolving an ionic compound?
The shape and charge distribution in a water molecule cause it to have a permanent dipole moment, which consist of a positive electric charge and a negative charge separated by a distance in space. Therefore, the part of a water molecule that corresponds to the negative charge of its dipole moment is attracted to positive ions, and the part of a water molecule that corresponds to the positive charge of its dipole moment is attracted to negative ions.

Why does a solid substance not contain conduct electricity but an ionic substance dissolved in water does?
Good question my friend. In the solid state the cations(+vly charged ions) and anions(-vly charged ions)are held together by strong electrostatic forces and hence they behave neutral.But when they are in fused state the oppositely charged ions get separated giving room to electric conductivity (cation of the salt is associated to -ve part of the solvent while anion is with +vly charged part).
Do the polyatomic ions meet the requirements to be called compounds?
No, because part of the definition of a compound is a requirement for lack of net electric charge, but any ion by must have a net electric charge.
Chemical formula for iron 111 bromide?
I'm assuming this was meant to be seeking the chemical formula for Iron (III) bromide, also known as Ferric bromide. In this case, the cation is Fe3+ (The iron III part of the name) The anion is Br- (the bromide part of the name) Since it is an ionic compound, you simply have to put the two ions within the compound in a ratio that will cause their net charge to balance out to zero. If we had one Fe3+ ion and three Br- ions, we would cancel out the charge, since (1)(3)+(3)(-1)=0 (1 ion of plus-3 charge + 3 ions of minus-1 charge). The end result is this formula: FeBr3
How are the ions distinguished from one another in writing formulas for compounds?
When writing a chemical formula, you must recognize the ions which are a part of the ionic compound. To distinguish the ions from one another, you must classify the ions as the cations, the monatomic anions and polyatomic anions.
A diamond symbol painted on a lane indicated what?
A diamond symbol painted on a lane indicates a car pool lane. It is usually not legal to drive in these lanes unless you are part of a car pool.

Is N the symbol for the element nitrogen?
Yes. More exactly, the letter "N" is the symbol for a single atom of nitrogen in a chemical formula. A subscript number following the symbol indicates the number of atoms present in the particular part of a specific molecular formula, but if that number is 1, no subscript is used.

Which ions in a total ionic equation are called spectator ionswhy?
In ionic equations the spectator ions are the ions that do not form a solute in the reactants side. They will have the symbol aq (for aqueous or in water)after it showing that is has not precipitated into a solid.
