can elements or compounds be consists of two or more type of elements

. Metalloids are the elements, which have properties that lie between those of metals and non-metals, e.g., arsenic, antimony, etc. Molecules of elements may consist of single atom, two atoms, or even more. All the hundreds of thousands of compounds..

An element is defined as a pure substance as it is made up of only one kind of atoms having the same atomic number. The smallest particle of an element is the atom, which has all the properties of that element. It cannot be further reduced to simpler substances by ord..

All matter can be broadly divided into two major groups "Pure" and "Impure". The term 'purity' has quite a different meaning in chemistry than in our day-to-day life. Normally when we refer to pure water, pure milk, etc., what is implied is that the water, milk etc., are free from h..

Summary - Pure substances are made up of only one type of constituent particles. They are homogenous and have a definite set of properties characteristic of themselves. An element is a pure substance that is made up of only one kind of atoms. An atom is the smallest particle of ..

Combination of Elements - Atoms of elements combine to form molecules of compounds. This combination can occur in two ways: either by electrovalent bonding or covalent bonding. In all chemical reactions it is the electrons from the outermost shell of an atom ..
