1) elements are composed of atoms 2) atoms of same elements = 3) atoms of different elements not = 4) atoms fomr compounds in definite ratios H2O
no.
In the 1800s John Dalton did some experiments and these are some of his magnificent work: * all elements are composed of atoms. atoms can not be divided or destroyed * atoms of the same element are alike * .atoms of different elements are not alike * the atoms of two or more elements can join together to form compounds
Elements are composed of atoms.
atoms are indivisible,tiniest particles of matter. they combine in simple whole no ratios to form elements or compounds. they can neither be created, nor destroyed.
