Answer 1

1. True. 2. True. 3. False. Change "Aristotle agreed" to "Aristotle disagreed". 4. True. 5. False. Change "5000 elements" to "118 elements".

Answer 2

1. The statement "It is possible to actually 'see' atoms using a scanning tunneling microscope." is true because scanning tunneling microscopes allow scientists to visualize individual atoms by scanning a sharp tip over a surface at a very close distance. 2. The statement "The submicroscopic world of the atom includes exotic particles called quarks and gluons." is true because quarks and gluons are fundamental particles that make up protons and neutrons within an atom. 3. The statement "Like other well-known Greek philosophers of the time Aristotle agreed with Democritus' ideas about atoms." is false. Aristotle did not agree with Democritus' ideas about atoms; instead, he believed in the concept of continuous matter. 4. The statement "The study of atoms has led to technological advances such as television and computers." is true because understanding atomic and subatomic particles has been crucial in the development of modern electronics and technology. 5. The statement "There are about 5000 elements, which combine to form the vast number of different substances in the world around us." is false. There are only about 118 known elements, not 5000.
