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.
Sodium chloride is ionically bonded and consists of alternating positive and negative ions. Each ion experiences substantial attraction to at least two ions of the opposite charge, so that there is no coherent unit smaller than the entire mass of solid sodium chloride in a particle that is capable of independent existence, as is required for a molecule.
Hydrogen and chlorine are both nonmetals, and nonmetals form molecular compounds when bonded together. Sodium is a metal and chlorine is a nonmetal, and a metal and a nonmetal form an ionic compound.
No, copper chloride is a compound composed of copper and chlorine elements. It is not a mixture of different substances but rather a specific chemical compound with a fixed composition.
Sodium chloride does not impart a distinct color to a flame test. When sodium chloride is subjected to a flame test, it typically results in a bright yellow flame due to the presence of sodium ions, rather than the chloride ions.
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.
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.).
Potassium chloride is an ionic compound, not a molecule. Ionic compounds like potassium chloride consist of ions held together by electrostatic forces, rather than individual molecules with covalent bonds.
Since there is no product, and only 1 reactant, it is not an equation, and thus, 4 molecules of sodium chloride
Pure hydrogen chloride is molecular. But Hydrochloric acid is hydrogen chloride dissolved in molecules. In this state it exists as ions rather than molecules.
Sodium chloride is ionically bonded and consists of alternating positive and negative ions. Each ion experiences substantial attraction to at least two ions of the opposite charge, so that there is no coherent unit smaller than the entire mass of solid sodium chloride in a particle that is capable of independent existence, as is required for a molecule.
Because sodium chloride form giant lattices without a limit between molecules.
Hydrogen and chlorine are both nonmetals, and nonmetals form molecular compounds when bonded together. Sodium is a metal and chlorine is a nonmetal, and a metal and a nonmetal form an ionic compound.
It would be inaccurate to speak of an NaCl molecule because NaCl is an ionic compound, not a molecule. NaCl is formed from an ionic bond between sodium ions (Na+) and chloride ions (Cl-), not from the sharing of electrons between atoms like in a covalent molecule.
CuCl2 exists as a compound composed of copper and chloride ions, rather than as discrete molecules of CuCl2. In a solid state, it forms a crystal lattice structure where Cu2+ ions are surrounded by chloride ions. When dissolved in water, it dissociates into Cu2+ and Cl- ions.
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)
there is no "paper" molecule... rather a combination of starches and protein links e.t.c.
Egg white suspension is made up of a long molecule made up out of amino acids this why but don't ask how I have no clue :)
