The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). An icon of chemistry, the periodic table is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order of their atomic numbers an approximate ...
Periodic table, in chemistry, is an organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern in which elements in the same column (group) have similar properties.
The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number. Scientists use the periodic table to quickly refer to information about an element, like ...

This handout will explain the functions of conclusions, offer strategies for writing effective ones, help you evaluate conclusions you’ve drafted, and suggest approaches to avoid.
Conclusions wrap up what you have been discussing in your paper. After moving from general to specific information in the introduction and body paragraphs, your conclusion should begin pulling back into more general information that restates the main points of your argument.
What should you include in a conclusion? Most conclusions include a restated thesis, a brief synthesis of key points, a statement of significance, and a final insight or clincher. How long should a conclusion be? Conclusions are typically one paragraph for short essays and may be two short paragraphs in longer papers. What makes a conclusion ...
Conclusions should not present new arguments or evidence but emphasize the main ideas of the text. Avoid just reiterating your main argument and points. Use the opportunity of the conclusion to connect with your readers one last time. Avoid cliches such as “in conclusion.”
Below is a range of copy-and-paste essay conclusions with gaps for you to fill-in your topic and key arguments. Browse through for one you like (there are 17 for argumentative, expository, compare and contrast, and critical essays).
Learn how to write strong conclusions in academic work. Explore key moves—summary, applications, evaluation, and future directions—plus examples from Oxford dissertations across disciplines.
Scientific research conclusions must summarize findings, highlight their significance, and suggest future research directions. These examples illustrate how to conclude research papers effectively.
Effective conclusions take the paper beyond summary and demonstrate a further appreciation of the paper’s argument and its significance: why it works, why it is meaningful, and why it is valuable.
