Dalton’s Atomic Theory Elements are made of atoms that cannot be divided Atoms of same element have same mass, atoms of different elements have different masses Compounds contain atoms of more than one element In compounds, atoms of different elements always combine in the same way Dalton’s A...
The Wave Model The most current atomic model is based on the principles of wave mechanics. According to the theory of wave mechanics, electrons do not orbit the atom like planets around the sun. It is impossible to determine the EXACT location of an electron. The Wave Model Instead we can ...

The Machine Age refers to the era from 1880 to 1945, where technology was advancing at such a rapid pace, punctuated by both the later stages of the Second Industrial Revolution and the start of the Atomic Age. Because of all the exciting progress in machine-related activity at the time–...

History of Chemistry and Atomic Structure Unit 3 Early ideas Chemistry has been around ever since people started working with dyes (more than 20,000 years ago) and hardening clay for ceramics (8,000 years ago). Later people worked with (pure) metals (Iron Age, Bronze age; 4,000 – 1,...
