Ions have superscripts, or tiny numbers above the element’s symbol, and they show if an atom has gained or lost electrons. A positive superscript means the atom lost electrons whereas a negative superscript means it gained electrons. For example, Ca +2 lost two electrons.

How do you write a superscript in chemistry?
The atomic number is written as a subscript on the left of the element symbol, the mass number is written as a superscript on the left of the element symbol, and the ionic charge, if any, appears as a superscript on the right side of the element symbol.
What is subscript in chemistry?
Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of. atoms of that element. If an element does not have a subscript, then it is understood that the subscript is 1. Li2Cl3 has two lithium atoms and three chlorine atoms.
What is the difference between a subscript and a superscript in chemistry?
It is usually smaller than the rest of the text. Subscripts appear at or below the baseline, while superscripts are above. Subscripts and superscripts are perhaps most often used in formulas, mathematical expressions, and specifications of chemical compounds and isotopes, but have many other uses as well.
What is a superscript number?
A superscript or subscript is a number, figure, symbol, or indicator that is smaller than the normal line of type and is set slightly above it (superscript) or below it (subscript).If you’re creating a footnote, you might also want to do this with a number.
How do you get a superscript?
You can find the superscript button on the ‘Home’ tab. It’s located near all the font options. Or you can use the keyboard shortcut: press Ctrl and Shift, then hit +.
Is the 2 in O2 subscript or superscript?
Explanation: The formula for a molecule of oxygen gas is O2 . It is a diatomic element, meaning it is composed of two atoms of oxygen, covalently bonded. The subscript 2 means that 2 atoms of oxygen are in one molecule of O2 .
What is a subscript and coefficient in chemistry?
Subscripts – Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element. Coefficient – A small whole number that appears in front of a formula in a balanced chemical equation.
Why do chemists use superscripts?
Chemical formulas also might use superscript after a chemical symbol to identify ions. Ions are atoms or molecules that do not have an equal number of protons and electrons, the negatively charged subatomic particle.For example, a superscript 3+ indicates the ion has three more protons than electrons.
What is the difference between superscript and subscript Class 4?
Superscript is when the text or number is above the text or number. Subscript is when the text or number is below the text or number.
Do subscripts count as moles?
Since compounds consist of elements, the chemical formulas of compounds also consist of elements with subscripts used to denote the number of atoms per molecule.Not only do subscripts denote ratios of atoms, they also denote the ratio of moles of element to one mole of compound.
What does the superscript represent in an electron configuration?
What do the superscripts in an electron configuration represent? Electron configuration notation simplifies the indication of where electrons are located in a specific atom. Superscripts are used to indicate the number of electrons in a given sublevel.
What is superscript example?
Superscript is the small letter / number above a particular letter / number. An example of superscript is 25. The number 5 above the number 2 is an example of superscript. Superscript can be used for exponents in mathematics.
Where do you use superscript?
Common uses for superscript formatting include:
- Ordinal numerals (e.g., 1st, 2nd, 3rd)
- Copyright and trademark symbols (e.g., ©, TM, ®)
- Footnote and endnote numbers.
- Mathematical functions (e.g., to denote an exponent)
- Chemical symbols (e.g., to show charges of ions)
Are footnotes superscript or subscript?
Revised on May 31, 2021. Footnotes are superscript numbers (1) placed within the body of text. They can be used for two things: As a form of citation in certain citation styles.

What is superscript HTML?
The tag defines superscript text. Superscript text appears half a character above the normal line, and is sometimes rendered in a smaller font. Superscript text can be used for footnotes, like WWW. Tip: Use the tag to define subscript text.
What is the superscript of oxygen?
Chemical abbreviation of Oxygen –
Molecular oxygen is abbreviated by the chemical symbol O2. The subscript 2, highlighted in O2 indicates the number of elemental atoms per molecule.
What is CO2 called?
Carbon dioxide is a chemical compound composed of one carbon and two oxygen atoms. It is often referred to by its formula CO2.
What is the subscript of hydrogen?
If we want to represent two atoms of hydrogen, instead of writing H H, we write H2. The subscript “2” means that two atoms of the element hydrogen have joined together to form a molecule.
