No. of atoms of the element in one molecule of the ionic compound
The subscript in a chemical formula tells you the number of atoms. In H2O there are 2 hydrogen atoms and 1 oxygen atom. In Al2O3, there are 2 aluminum atoms and 3 oxygen atoms.
This subscript is the number of atoms in a molecule.
The meaning is number of atoms in formula.
uhh I hoped I helped
number of atoms
it indirectly tells us the number of electrons present in the element
eg: O2(2 is in subscript) it tells us that there are 2 oxygen atoms which have joined together to attain neutrality charge
The electronic configuration of oxygen is = 2,6
so oxygen needs 2 electrons to become neutral ( to have 8 electrons in valence(last) shell )
O2 is a covalent bond (if i am not wrong) i.e 2 oxygen atoms share 2 electrons EACH
Al2O3 (2 and 3 are subscript)
this defines that there are 2 atoms of aluminium and 3 atoms of oxygen which allowed them to become neutral (no charge)
In a molecular formula, the subscript tells us the number of atoms of the element that are present in one molecule of the compound. For instance,H2O tells us that there are two hydrogen and one oxygen atom per molecule of water. As for ionic compounds, it tells us the number of atoms present in one formula unit of the compound.
An ionic compound is an example of a chemical compound.
A covalent compound, not ionic
Copper(II) sulfide is an ionic compound.
No, like all sodium (Na) compound it is ionic.
In a binary compound, the subscript for a compound's formula would tell us how much of a certain atom there is.
Yes. No subscript means that there is just one.

Metal and Non-mental.
Subscript (:This is a subscript: (Na2) the "2" is the Subscript.
Potassium Chloride (KCl) is an ionic salt of a weak acid and a weak base.
A single atom of each constituent element in the molecular formula unit.
This depends on the compound.

No Its an ionic compound
pentanitrogen heptoxide
The 3 is the coefficient because it is the big number before the compound whereas the subscript is the small number after the compound.
