2. sodium and chlorine
NaCl is a molecule composed of two atoms Na and Cl.
The ratio Na/Cl is 1 in the formula unit.
The formula unit of NaCl (sodium chloride) contain 2 atoms.
Sodium (Na) has the positive charge; the chloride ion (Cl) has the negative charge.
Atomic mass of sodium = 22.99 Atomic mass of chlorine = 35.45 Total mass = 58.44g 58.44g of NaCl contains 6.023 x 1023 atoms ... 18.035g of NaCl contains 18.035x6.023x1023/58.44 = 1.858x1023 atoms!
NaCl is a molecule composed of two atoms Na and Cl.
NaCl is an example. It is an ionic compound.
The ratio Na/Cl is 1 in the formula unit.
One molecule has two atoms (one Na and one Cl). So 3NaCl will have six atoms.
The formula unit of NaCl (sodium chloride) contain 2 atoms.
There are 1.41 e24 atoms of Na in 2.35 mol of NaCl.
Sodium chloride (NaCl) is an unique compound.
Sodium chloride (NaCl) is an unique compound.
The answer is 12,004428258.1023.
Two kinds: sodium (Na) and chlorine (Cl).
The formula unit -NaCl - (not a molecule) contain two atoms.
In one molecule of NaCl there are two ions, Na+ and Cl-.
