2, that's what the 2 means.
3 atoms
5 atoms (one potassium, one chlorine and three oxygen) are there per molecule of KClO3
1 carbon and 4 chlorine
There is 1 hydrogen atom and 1 chlorine atom in Hydrogen Chloride.
5, that's what Cl5 (usually written w/ a subscript) means
Chlorine is an element, not a compound. Moreover, its a diatomic molecule, that is, a molecule of chlorine contains two atoms of chlorine.
A chlorine molecule has the formula Cl2, so it contains two chlorine atoms.
2 -- Cl2 is a molecule of Chlorine and as can be seen it has two atoms.
3 atoms
It has two chlorine atoms.
Cl2 is a molecule formed of 2 atoms of Chlorine.
2
4. 4 atoms of chlorine, one of carbon. The formula is CCl4
There is one covalent bond in a chlorine molecule. The formula for a chlorine molecule is Cl2, which means that there are two chlorine atoms bonded together per molecule. The structural formula for a molecule of chlorine is Cl-Cl, in which the line in between the symbols for the two atoms represents a single covalent bond.
Chlorine gas is a diatomic molecule, Cl2. Two atoms per molecule. A mole contains Avogadro's Number of particles, that being (approximately) 6.02 x 1023. Hence, the number of atoms in one mole of chlorine gas is twice Avogadro's Number, or approximately 1.204 x 1024.
5: One silicon and four chlorine atoms.
There are _no_ fluorine atoms. Rather, there are four chlorine atoms.
