Science Prep 1 Atomic Structure Atomic And Mass Number Unit 1 The number of protons in the nucleus of an atoms is called. atomic number. the mass of a proton is. about the same as a neutron. alpha particles are. 2 protons and 2 neutrons. the denisty of a nucleus is? much greater, it is empty space and there isnt much mass but there is low denisty and alot of volume. describe beta decay. A. being the first to use the term "atom". b. describing the orbits of electrons. c. discovering the proton. d. identifying substances by weight. d. identifying substances by weight. henri becquerel and the curies found out that . a. atoms were not indivisible and indestructible. b. the atom had a nucleus.

This unit explores the atomic theory of matter, the foundational premise of chemistry. learn about moles and molar mass, mass spectrometry, electron configurations, periodic trends, and more. practice what you’ve learned and study for the ap chemistry exam with more than 100 ap aligned questions. The number of protons determines an element's atomic number and identity; protons have a mass of approximately 1 atomic mass unit (amu) neutrons are electrically neutral particles found in the nucleus alongside protons neutrons contribute to the mass of an atom but do not affect its atomic number; like protons, neutrons have a mass of about 1 amu.
