We look at atomic theory, discuss atomic structure, and finally describe the periodic table, which organizes the elements. indivisible The word atom comes from the Greek atomos, meaning atom
WebIt stated that all matter was made up of small, indivisible particles known as ‘atoms’. All substances, according to Dalton’s atomic theory, are made up of atoms, which are indivisible and indestructible building units. While an element’s atoms were all the same size and mass, various elements possessed atoms of varying sizes and masses. WebAn atom consists of two regions. The first is the tiny atomic nucleus, which is in the center of the atom and contains positively charged particles called protons and neutral, …
