Why are the particles in a sodium chloride molecule called ions rather than atoms?

They are called ions because they have an electric charge. The sodium gives up its (valence) electron so it gains a positive electrical charge. The chlorine gains this extra electron so it gains a negative electrical charge.
IONS always refer to particles WITH AN ELECTRICAL CHARGE.

Why was evaporation used to determine the mass percentage of potassium chloride rather than filtration or recrystallization?

Why is the II in copper II chloride important?
the II means that the charge of the copper, in this case, is +2, rather than, say, +1, which is copper's other possible charge. the formula for copper II chloride is CuCl2, rather than copper I chloride, which is simply CuCl. for all transition metals which have multiple charges, it is necessary to state the particular charge thet the atom is using.
What does tin and chlorine make?
When Tin and chlorine combine it creates either:-SnCl2, called tin(II) chloride, stannous chloride. This is molecular in the gas phase and forms polymeric covalent chains in the solid (mp. 247 anhydrous form)), but dissolves to form Sn2+ which may hydrolyse. The electronegativity difference is only 1.2 so it would be expected to be covalent rather than ionic.A covalent molecular compound SnCl4, tin(IV) chloride, stannic chloride, tin tetrachloride.
An unknown compound dissolves in water but the solution does not conduct electricity?
If a compound dissolves into water and allows for the conductance of electrical current its said to be ionic and an electrolyte. Sodium chloride (NaCl) or table salt exhibits this property. Sugar is a compound that will dissolve in water but not conduct current. Sugar is not an electrolyte or ionic; rather a covalent molecule.
Is potassium chloride sublime?
Potassium chloride also known as KCl is a rather ordinary salt, abundantly present in sea water, edible by human beings (in moderate amounts only) and not particularly sublime.
What contains one sodium and one chloride atom?
A "molecule" of sodium chloride, common salt. (Because this is an ionically bonded compound, its molecule is a formal concept only, rather than a unit that can be isolated.).
Is hydrochloic acid a molecule?
Pure hydrogen chloride is molecular. But Hydrochloric acid is hydrogen chloride dissolved in molecules. In this state it exists as ions rather than molecules.
Why is NaCl not a molecule?
Because sodium chloride form giant lattices without a limit between molecules.
Why does increasing the concentration of a reactants increase the reaction rate?
Because it increases the probability of collisions
What do you observe when the mouth of the bottle of hydrochloric acid and a bottle of ammonia are brought together?
You might see the smokey 'fume' of ammonium chloride solid particles formed by reaction of escaping ammonia and hydrogen chloride gas, at best seen when solutions are rather concentrated.NH3(g) + HCl(g) --> NH4Cl(s)
Why do marble particles stay together rather than mixing with water particles?
they are concealed
What is a hetrogeneous mixture?
A heterogeneous mixture is a physical combination of substances where the individual components can be distinguished from one another. Examples include a salad, trail mix, or a mixture of oil and water.
How many nanometers across is the molecule of paper and what is this molecule made of?
there is no "paper" molecule... rather a combination of starches and protein links e.t.c.
What happens when salt goes into water?
Salt dissolves in water. Here's a rather complicated explanation of why this happens: Salt is made when a sodium atom loses one electron, and the electron moves to a chloride atom. When this happens, the sodium atom becomes positively charged and the chloride atom becomes negatively charged. Positive and negative atoms attract each other, so the sodium and the chloride are attracted and form an ion called sodium chloride (otherwise known as salt). Water molecules are made of two hydrogen atoms and one oxygen atom. The electrons in the molecule tend to spend more time around the oxygen atom. This gives the oxygen atom in the molecule a slightly negative charge (and the hydrogen atoms slightly positive charges). When you put salt in water, the ionic bond between the positive sodium and the negative chloride breaks. The positive sodium atom is pulled to the negative end of the water molecules, and the negative chloride atom is pulled to the positive end of the water molecule.
Why is water a molecule rather than an atom?
Water is a molecule rather than an atom because it consists of more than one atom. In fact it consists of atoms of two different elements.
What happens to the particles that make up a solid if enough heat is added to melt it?
The particles begin to separate. If it turns into a gas, the particles will be more spaced out. Rather to a liquid.
Is NaCl butter?
Nope. NaCl is the formula for Sodium Chloride. It is the most common type of salt. Therefore, it is not butter, but rather a table salt.
