How many hydrogen atomes are present in one molecule of ammonium acetate NH4C2H3O2?
To answer this kind of question, all that is required is to add the subscripts that appear immediately after the atomic symbol of the atom in question, remembering that if there is no explicitly written subscript, a subscript of 1 is implied. In this instance, the symbol for hydrogen occurs twice, once with a subscript of 4 and once with a subscript of 3. Therefore, there are 4+3 or 7 hydrogen atoms in the formula unit.
What do the symbol represent in a chemical formula 0 atoms 1 atoms 2 atoms or the need for subscript?
The symbols in a chemical formula represent the elements present in the compound. A zero atom, or no atom, is denoted by omitting the element symbol from the formula. A subscript of 1 is not usually written in a chemical formula as it is implied. If there are more than one atom of an element, the number of atoms is indicated by a subscript after the element symbol.
Do you have to use subscript in chemical formulas?
Not every chemical formula requires subscript. For example table salt is NaCl, sodium chloride. No subscript. But most chemical formulae do require subscript, such as water, H2O.
How can the number of atoms of an individual element be determined by using a chemical formula?
The subscript number after the element symbol, such as the 2 in H2O, tells how many atoms in each molecule. In the example, the 2 refers to H (hydrogen). If there is no number present, then 1 is implied. So H2O has 2 hydrogen and 1 oxygen.
What is the superscript and subscript for platinum?
The superscript for platinum is Pt2+ and the subscript for platinum is Pt.
What is implied when there no subscript on a element?
When there is no subscript on an element, it is implied that one atom of that element is present. For example, "H" would represent one atom of hydrogen.

What is the number of atoms in ZnI2?
Three: Count the subscripts and add them to get the answer. (A subscript of 1 is implied by the atomic symbol itself.
How do you subscript on a Dell?
ctrl = for subscript ctrl shift = for superscript
What does the subscript g on H2Og signify?
the subscript g after H2O indicates that it is water vapour, a gas, which is what the subscript g stands for. If there was a subscript s after the H2O, it would mean that H2O is in a solid form as ice. If there was a subscript l it means that H2O is in the liquid form as water.
How do you write a subscript on excel chart legend?
You are not able to format a single character as subscript, but you can change the entire ledged text to subscript. Right-click on the ledged, select Font, and click on the Subscript option.

How many total atoms are found in one molecule of H2O?
One molecule of H2O contains a total of three atoms: two hydrogen atoms and one oxygen atom.
