Examples of period in the following topics:

The Periodic Table of Elements
- The periodic table is a tabular display of the chemical elements.
- Groups usually have more significant periodic trends than do periods and blocks, which are explained below.
- A period is a horizontal row in the periodic table.
- Here is the complete periodic table with atomic numbers, groups, and periods.
- Explain how properties of elements vary within groups and across periods in the periodic table
-
Perpetual vs. Periodic Counting
- Perpetual inventory updates the quantities continuously and periodic inventory updates the amount only at specific times, such as year end.
- Periodic inventory is when information about amount and availability of a product is updated only periodically.
- Most companies who use periodic inventory perform this at year-end.
- In earlier periods, non-continuous or periodic inventory systems were more prevalent.
- Many small businesses still only have a periodic system of inventory.

Calculating the Payback Period
- To calculate a more exact payback period: Payback Period = Amount to be initially invested / Estimated Annual Net Cash Inflow.
- Payback period in capital budgeting refers to the period of time required for the return on an investment to "repay" the sum of the original investment.
- Payback period is usually expressed in years.
- The modified payback period algorithm may be applied then.
- To be more detailed, the payback period would be: 4 + 2/7 = 4.29 year.

Pre-Cambrian Animal Life
- Early animal life (Ediacaran biota) evolved from protists during the pre-Cambrian period, which is also known as the Ediacaran period.
- The time before the Cambrian period is known as the Ediacaran period (between 635-543 million years ago), the final period of the late Proterozoic Neoproterozoic Era .
- Fossils of (a) Cyclomedusa and (b) Dickinsonia that evolved during the Ediacaran period.
- (a) Earth's history is divided into eons, eras, and periods.
- The Ediacaran period was the final period of the Proterozoic Era which ended in the Cambrian period of the Phanerozoic Era.
-
Advantages of the Payback Method
- Payback period in capital budgeting refers to the period of time required for the return on an investment to "repay" the sum of the original investment.
- All else being equal, shorter payback periods are preferable to longer payback periods.
- Although primarily a financial term, the concept of a payback period is occasionally extended to other uses, such as energy payback period (the period of time over which the energy savings of a project equal the amount of energy expended since project inception).
- The payback period is an effective measure of investment risk.
- The project with a shortest payback period has less risk than with the project with longer payback period.
-
Calculating Values for Fractional Time Periods
- Up to this point, we have implicitly assumed that the number of periods in question matches to a multiple of the compounding period.
- Compounding periods can be any length of time, and the length of the period affects the rate at which interest accrues.
- In this case, you need to find the amount of money that is actually in the account, so you round the number of periods down to the nearest whole number (assuming one period is the same as a compounding period; if not, round down to the nearest compounding period).
- Even if interest compounds every period, and you are asked to find the balance at the 6.9999th period, you need to round down to 6.
- The last time the account actually accrued interest was at period 6; the interest for period 7 has not yet been paid.
-
Number of Periods
- In , nrepresents the number of periods.
- A period is just a general term for a length of time.
- If one period is one month, the discount rate must be X% per month.
- In compound interest, the interest in one period is also paid on all interest accrued in previous periods.
- Define what a period is in terms of present value calculations
-
Single-Period Investment
- A period is a general block of time.
- Usually, a period is one year.
- The number of periods can be represented as either t or n.
- Let's go through an example of a single-period investment.
- Since this is a single-period investment, t (or n) is 1.
