Q1. What does element mean? An element is a substance whose atoms all have the same number of protons: another way of saying this is that all atoms of a given element have the same number of protons. Elements are the simplest chemical forms and thus can not be broken down through chemical reactions. Q2. What are the main elements?
An element is a substance whose atoms all have the same number of protons: another way of saying this is that all of a particular element's atoms have the same atomic number. Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions.
