Synergy - 4.1.2 - Atomic Structure 0.0 / 5 ? ScienceChemistryGCSEAQA Created by: loganmarsden01Created on: 15-06-16 10:10 What is Atomic structure? Atomic structure is how the atoms are arranged. 1 of 8 What are the sub-atomic particles called? Protons, Neutrons, Electrons. 2 of 8 What is the overall charge of an atom? The overall charge is neutral. 3 of 8 What are isotopes? Isotopes are atoms of the same element with a different mass. 4 of 8 What are the charge of the sub-atomic particles? Protons- +, Neutrons- +, Electrons- -. 5 of 8 What are the masses of the sub-atomic particles? Protons- 1, Neutrons- 1, Electrons- Negligible. 6 of 8 What is Quantum Theory? the modern atomic model. Electrons exist in a "cloud" around the nucleus with different energy levels. 7 of 8 When the mass of the born atom is calculated, the mass of the electrons is ignored. Why is the mass of the electrons ignored? The mass of the electrons is ignored because the electrons are negligible. 8 of 8
