Element is the simplest form of a pure substance that can neither be broken into nor built from simpler substances by ordinary physical and chemical methods. Atomic Number An important number in an element is the atomic number.

An element is a pure substance consisting only of atoms with the same numbers of protons in their atomic nuclei. Examples of elements include iron oxygen hydrogen gold and helium. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions. What Is an Element.

The equivalent of an element can be defined as the amount of the element that reacts with or supplies 1 mole electron in a reaction so if you try a bit you can conclude that 1 equiv of an element is equal to 1n mole of element where n is the valency of the element.

Even if it strongly perfers the 1 ion the neutral atom is the elemental form. Science Chemistry for Kids An element is a pure substance that is made from a single type of atom. The elemental state is defined as having all electrons in the ground state configuration even if that form never occurs in nature. Elements are the building blocks for all the rest of the matter in the world.

An element is a substance made up of only one type of atom all with the same number of protons. An element in science or specifically chemistry can be defined as any substance that cannot be separated into different substances by ordinary chemical methods Each element is made of a specific and unique type of atom. A typical atom consists of protons neutrons and electrons. Electrons are particles with a negative charge.

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. 122 rows In chemistry an element is a pure substance consisting only of atoms that all have.
