The number to the lower right on an element symbol indication the number of atoms of that element?
The number to the lower right on an element symbol is the atomic number, representing the number of protons in the nucleus of an atom of that element. It does not indicate the number of atoms of that element in a compound; that information is conveyed through subscript numbers next to the element symbol in a chemical formula.
The subscript in a chemical formula refers to the?
The subscript in a chemical formula refers to the number of atoms of that element present in the molecule. It is a small number written at the lower right of the element symbol. For example, in the formula H2O, the subscript 2 indicates that there are two hydrogen atoms in each water molecule.
What type of number after a chemical symbol tells how many atoms of that elements in a single molecule?
The number after a chemical symbol in a chemical formula represents the number of atoms of that element in a single molecule. This number is called a subscript, and it indicates the ratio of atoms in the compound.
What part of the chemical formula indicates the number of atoms or molecules involved?
coefficients
Where does a subscript belong in a chemical formula?
A subscript belongs immediately after the symbol of an element in a chemical formula to indicate the number of atoms of that element present in the compound. It is written as a small number at the bottom right of the element's symbol.
Where does the subscript that indicates the number of atoms relative to a chemical symbol located?
The subscript indicating the number of atoms relative to a chemical symbol is located immediately after the chemical symbol and is written in a smaller font size at the bottom right corner of the symbol.
The number to the lower right on an element symbol indication the number of atoms of that element?
The number to the lower right on an element symbol is the atomic number, representing the number of protons in the nucleus of an atom of that element. It does not indicate the number of atoms of that element in a compound; that information is conveyed through subscript numbers next to the element symbol in a chemical formula.
What is a number written to the right of a chemical symbol?
The number of atoms present in a given molecule. Water ; H2O ; means TWO hydrogen atoms and ONE oxygen atoms Similarly Carbon dioxide ; CO2 ; means ONE atom of carbon and TWO atoms of oxygen in the molecule. NB Although 'Answer'com' does not allow me to show it, these numbers after an atom should be written 'subscript'.

Where is the oxidation number written?
In a molecule the oxidation number is written in ROMAN numerals after the given element. Although all Group oxidise, any one Group only oxidises by the Group Number, except the Transition Element. These lie between Group '2' & '3' in the Periodic Table. If we take say, potassium permanganate (KMnO4) The manganese (Mn) has different oxidation states. In the above molecule KMnO4 we could write it as KMn(VII)O4. The potassium(K) is a Group '1' element so its oxidation state is Always '1'. The oxygen (O) has a standard at '-2' . So for four oxygens the overall moiety on oxygen is 4 x -2 = -8 Composing a little sum Mn + 1 - 8 = 0 (Zero for a neutrally charged molecule). We have Mn = 8 - 1 = (+)7 (Roman Numerals VII). The oxidation Number tells us that seven of the manganese electrons in the outer electron energy shell take part in bonding. Compare to nitrogen in Ammonia (NH3) Nitrogen has five electrons in its outer energy (valance) shell , but only three of those five electrons are involved in bonding to hydrogens, leaving a 'lone pair' of unbonded electrons in nitrogen of ammonia. So nitrogen's oxid'n state in ammonia is '+3'. Archaically, there is a subtle change of name to indicate different oxidation states. e.g. Ferrous chloride (Fe(II)Cl2 Ferric chloride (Fe(III)Cl3 However, remember that Oxidation Number refers to the number of electrons in the outer energy(valance) shell that are involved in Bonding.
Where does a subscript that indicates the number of atoms appear?
A subscript that indicates the number of atoms typically appears to the lower right of the chemical symbol in a chemical formula. It represents the number of atoms of that element present in the compound.
What is the chemical symbol of an element?
A chemical symbol for an element is one or two letters. These are found on the Periodic Table of elements. The chemical symbol is an abbreviation of the chemical element name.Example: O is the chemical symbol for Oxygen.K is the chemical symbol for Potassium.Pb is the symbol for lead.He is the symbol for helium.
What is the difference between a subscript and coefficiant?
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation.
What part of the chemical formula indicates the number of atoms or molecules involved?
coefficients
Where does a subscript belong in a chemical formula?

Where are subscripts placed in chemical equations?
Right and down the symbol of a chemical element.
