A superscript in a chemical symbol indicates the charge of an ion or the mass number of an isotope. For example, a superscript of +2 next to a symbol (like ( \text{Mg}^{2+} )) shows that the ion has a positive charge of 2, while a mass number (like ( \text{C}^{12} )) indicates the total number of protons and neutrons in the nucleus of the atom. This notation is essential for understanding the chemical properties and behavior of elements and compounds.

What does a three letter chemical symbol show?
A three-letter chemical symbol represents an element in the periodic table. Each element is assigned a unique symbol comprised of one to three letters. These symbols are used in chemical formulas and equations to represent specific elements.
What is subscript for h2?
For 'H2' the subscripot is '2'. Although 'Answers' doesn't allow me to show it, the number '2' shoulkd be written slightly smaller, slightly lower, so that the base of the figure '2' is below the writing line'.
How do you show charge over atom 2 or 2?
This cannot be shown correctly on Answers. Firstly, if it's charged it's an ion not an atom. The correct notation is symbol then the number as a superscript, then the plus or minus as a superscript.

In the chemical formula of a binary ionic compound the last part is?
The last part in the chemical formula of a binary ionic compound is usually the anion, which is negatively charged and is represented by its element symbol. It is written after the cation in the formula to show the complete chemical composition of the compound.
What does a three-letter chemical symbol show?

What symbol would you use to show that a reacting substance was a gas?
The symbol (g) is typically used to represent a gas in a chemical reaction equation.
How can you use an exponent to show powers of 10?
The exponent in this case is the small number written in superscript (raised) to the right of the 10.
What is the symbol that means produces in a chemical reaction?
The symbol that means "produces" in a chemical reaction is an arrow pointing to the right (→). This arrow is used to show the direction in which the reactants are transformed into products during a chemical reaction.
What is the chemical symbol for heated water?
All forms of water are shown as H2O. To show the different states use (g) for gas, (s) for solid, and (l) for liquids. To show added heat, you can use the triangle or "delta" symbol. Just like when writing a balanced chemical equation.

How do you write 900 in expanded notation using exponents?
900 = 9 x 100 9 can be written as 3 to the power of 2 100 can be written as 10 to the power of 2 It is then written as (3 squared) x (10 squared) I cannot with the editor we use show how to write 3 squared or 10 squared but I hope you know ( 3 superscript 2) x (10 superscript 2).
What is the symbol for soluble?
The symbol for a substance that is soluble is (aq) which means aqueous or in aqueous solution.
