Scientific notation is a way of representing numbers, usually very large or very small, in the forma*10^b where 1 <= |a| < 10 is a decimal number and b is an integer (negative or positive). a is called the mantissa and b is called the exponent.
To convert a number to scientific notation:
- If the number has no decimal point, then add one at the end.
- Then move the decimal point to just after the first digit while counting the number of places you have moved it.
- The mantissa of the new number, formed after moving the decimal point is a.
- If the original number is negative, then so is a.
- The number of places to the left that the decimal point was moved is b. If it was moved to the right, then b is negative.
For example:
-0.00023004 becomes -2.3004*10^-4
0.00023004 becomes 2.3004*10^-4

Importance of scientific notation?
Scientific notation provides a compact and clear way to express very large and very small numbers.
What is a type of notation used to express very large or very small numbers called?
scientific notation
What are the advantages of using scientific notation to express very large and very small numbers?
Scientific notation lets us express a large or a small number without having to write a lot of zeros before or after it. Try writing out 3 x 10^9000 without scientific notation.
Why scientific notation useful to scientists?
Scientific notation produces convenient numbers when working with very small or very large quantities.
What is the goal of the scientific notation?
Representation of very large or very small numbers or quantities in a straightforward way.
Do scientist use scientific notation to solve science problems?
Sometimes. Scientific notation is used to express very small or very large numbers. If the problem does not involve any such numbers then there is no need for scientific notation.
Can rare earth metals be used in scientific notation?
Scientific notation is often used to represent very large and very small numbers. Actually, you can also express a "normal-sized" number in scientific notation. So, whenever there is a number, you may use scientific notation.
When is it appropriate to use scientific notation instead of standard form?
It is appropriate to use scientific notation when dealing with very large or very small numbers, particularly when the numbers have many zeroes. Scientific notation is a more compact and efficient way to express these numbers, making calculations and comparisons easier. Additionally, scientific notation is commonly used in scientific fields to express measurements and mathematical equations.
What is a scientific notaton?
Scientific notation is a way to express very large (or very small) numbers. You would represent 1,000,000,000,000,000,000,000 as 1*1021.
Why is the use of scientific notation important to chemistry?
Scientific notation is useful because it helps to read values' significant figures (sigfigs). For example, the number: 6.02^(-10) is much easier to read than .000000000602. When dealing with especially large or small quantities, scientific notation makes it easier to understand how big or small the quantity is.
