Atoms and bonds are often represented in chemical structures by balls and sticks, but like
organelles, are more complex than they are often represented. Later, you’ll learn about bonds. For
now, you’ll explore what an atom is. – \u2714\u2714An atom is the smallest unit of ordinary matter that
forms a chemical element. It is made up of protons, neutrons, and electrons.
Which of the following would be a good definition of the atom according to Democritus? – \u2714\u2714A
piece of something that is as small as possible
What was J. J. Thomson’s biggest difference from Democritus’ model? – \u2714\u2714Atoms broken into
smaller pieces
Which scenario below do you think is most likely for this experiment’s results? Make a
hypothesis. – \u2714\u2714The beam of alpha particles will pass through mostly unchanged and some will
bounce back
Why did this surprise Rutherford? – \u2714\u2714Thomson’s model of the atom had a diffuse positive
charge, so the particles should not have been deflected very far.<\/li>\n<\/ol>\n\n\n\n
