What is the nuclear notation for europium?
superscript 63 and subscript 152 Eu (the super and subscript go before the symbol with superscript on top of the subscript)
What is difference between coefficient and a subscript?
The coefficient applies to all of the elements in the compound whereas the subscript applies to only the select elements; unless the subscript follows parenthesis, in which case it applies to all elements inside. ==========================================================Hope it helped!

What is the small number below a variable called?
A subscript.
What is super-subscript?
A superscript is a character set or printer for scripters
What is meant by subscripts?
A subscript is something written below the line.
When a polyatomic ion is in parentheses and there is a subscript on the outside of it is the polyatomic ion multiplied or add?
Multiplied.
How many atoms are in C8H16?
24: The answer to the number of atoms present in a formula that does not include parentheses is always the sum of all the subscript numbers in the formula plus one for each type of atom shown without a subscript. If the formula does contain parentheses, all the subscript numbers inside the parentheses should be multiplied by the subscript number after the closing parenthesis itself before the sum of all subscripts is taken.
How many atoms in the equation CH4 plus 2 O2?
The number of atoms of a particular element in an equation is obtained by multiplying the subscript if any immediately after the symbol for the atom by the coefficient if any of the molecule containing the atom. If a formula includes parentheses, the subscript after the parentheses is also multiplied by the subscript if any of each atomic symbol within the parentheses. If there is no explicit subscript or coefficient, the number 1 is to be assumed. Applying these rules shows that the given equation contains one carbon atom, four hydrogen atoms, and four oxygen atoms, for a total of nine atoms altogether.
What is Ag subscript 3 PO subscript 4?
Ag3PO4 would be silver phosphate.

How do you indicate the number of molecules in a substance?
The subscript outside the parentheses: (H2SO4)2
How many atoms does a molecule contain?
It depends on the molecule! If you have a molecular formula for a molecule and the formula does not contain parentheses, you can find the number of atoms in it by adding all the subscripts, treating no subscript as the number 1. If the formula does contain parentheses, first multiply any subscript within the parentheses by the subscript at the end of the parentheses, then add these modified numbers to those of any other atoms in the formula that are not in parentheses.
The subscript of ammonium in a compound formed between ammonium and phosphate ion is?
3
Number and type of element of the atom fe2o3?
Four: the answer to such questions is always obtainable by summing the subscripts in the formula (remembering that no explicit subscript means one atom per formula unit of the element symbol without a subscript) unless the formula includes parentheses; in that instance, the subscripts within the parentheses must be multiplied by the subscript after the right parenthesis before summing.
How many oxygen atoms are there in aluminium nitrate?
The formula unit for aluminum nitrate has the formula Al(NO3)3. Subscripts within parentheses are multiplied by the subscript after the parentheses. Therefore, this formula unit contains nine oxygen atoms, three nitrogen atoms, and one aluminum atom for a total of 13 atoms.
How should more than one polyatomic ion be indicated in a chemical formula?
One reason is that the composition of a polyatomic ion is fixed, just as that of a compound is fixed. If more than one polyatomic ion is present in an ionic compound, the use of parentheses allows a subscript to be used after the right parenthesis to designate the number of ions just as such subscript is used to designate the number of atoms in a compound.
What is the purpose of a subscript in a chemical formula?
The subscript tells you how many atoms of a certain element are in the representative particle of that substance. For example, H2O means 2 hydrogens and 1 oxygen. (The absence of a subscript means there's just 1.) The subscript only applies to the element immediately before it, unless the subscript occurs outside a set of parentheses, in which case it applies to everything inside the parentheses.
