Study Notes

Scientific Notation

Scientific Notation is a way to write very large or very small numbers in a more compact and convenient form.
The format of scientific notation is Nx10^n, where:
- N is a number between 1 and 10.
- n is a positive or negative integer called the exponent.
To represent a number in scientific notation, follow these steps:
- Move the decimal point of the number to the left or right until there is one non-zero digit to the left of the decimal point.
- Count the number of places moved. If the decimal point is shifted to the left, the exponent will be positive, and If the decimal point is moved to the right, the exponent will be negative.
Example: The number of atoms in 12g of carbon-12 (602,200,000,000,000,000,000,000) can be written in scientific notation as 6.022 x 10^23.
Example: The extremely small mass of a single carbon atom in grams (0.0000000000000000000000199) can be written in scientific notation as 1.99 x 10^-23.
