www.ncert.nic.in4.2 The Structure of an Atom We have learnt Dalton’s atomic theory in Chapter 3, which suggested that the atom was indivisible and indestructible. But the discovery of two fundamental particles (electrons and protons) inside the atom, led to the failur e of this aspect of Dalton’s atomic theory. It was then considered necessary to

projects.iq.harvard.eduChapter 1 Atomic Structure & Chemical Bonding 4 biological matter, about 99%, is made of just six elements: carbon, hydrogen, nitrogen, oxygen, sulfur, and phosphorus. Most biological molecules, such as proteins, carbohydrates, lipids, and nucleic acids, are exclusively composed of these elements. A few other atoms also play roles in biology;

Electronegativity: The atoms should have similar electronegativity, or compounds will form; 4. Valences: If (1) -(3) are favorable, then the metal of lower valence will dissolve more in crystal structure of the higher valence metal than vice
