What is an element in science?
1) In chemistry and physics, an element is a substance that cannot be broken down into simpler components by any non-nuclear chemical reaction. An element is uniquely determined by the number of protons in the nuclei of its atoms.
What is an element and give an example?
A chemical element is a substance that cannot be further broken down by any chemical reaction. Each element has a unique number of protons in its atom. For example, a hydrogen atom has 1 proton, while a carbon atom has 6 protons. Varying the number of electrons in an atom of an element produces ions.
What are all the examples of elements?

What are the 5 most important elements?
1. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles. These five elements also constitute the bulk of our diet; tens of grams per day are required for humans.
What are the 3 main types of elements?
Group and Periods of the Periodic Table of Elements. The three major groups on the Periodic Table are the metals, nonmetals and metalloids. Elements within each group have similar physical and chemical properties.
What are the basic elements?
Classical elements typically refer to water, earth, fire, air, and (later) aether, which were proposed to explain the nature and complexity of all matter in terms of simpler substances.
Is water an element?
Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen.

Is fire an element?
Fire is made up of many different substances, so it is not an element. For the most part, fire is a mixture of hot gases. Flames are the result of a chemical reaction, primarily between oxygen in the air and a fuel, such as wood or propane.

How do you calculate mass number?
Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How do you find the number of elements in a period?
- the formula to find the number of elements in a given period is.
- where n is the period number.
- if n is even – ((n+2)2)/2.
- if n is odd – ((n+1)2)/2.
