GENERAL KNOWLEDGE

Detailed explanation-1: -Elements are a class of chemicals that are the simplest forms of matter; those elements in nature range from hydrogen to uranium. Metals (such as aluminum and silver) are elements that tend to be malleable (can be shaped or formed by hammering or pressure without breaking) and ductile (can be drawn into wires).

Detailed explanation-2: -Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions. Elements can only be changed into other elements using nuclear methods. Although an element’s atoms must all have the same number of protons, they can have different numbers of neutrons and hence different masses.

Detailed explanation-3: -An element is the simplest substance and cannot be broken down using chemical methods. It is a substance consisting of atoms which all have the same number of protons (atomic number). For example, oxygen, hydrogen etc. There are 118 elements known till date.

Detailed explanation-4: -The simplest element on the periodic table – hydrogen – is made of zero neutrons, one proton and one electron. The more complex an element, the more neutrons, protons and electrons an atom will contain.
