ChemistryAtomsGCSEOCR Created by: tashlyn20Created on: 23-04-16 12:41 what is the relative charge and mass of a proton? +1 is the charge, 1 is the mass 1 of 10 what is the relative charge and mass of an electron? -1 is the charge, 0.005 (0) is the mass 2 of 10 what is the relative charge and mass of a neutron? 0 is the charge and the mass is 1 3 of 10 how do you work out the number of neutrons, proton or electrons in an atom? Proton- the same as the atomic number. Electron- same as the atomic number. Neutrons- take away the atomic number from the mass number 4 of 10 what is an isotope? an element with the same atomic number but different mass numbers 5 of 10 how many protons, neutrons and electrons does carbon-14 have? it has 6 protons, 8 neutrons and 6 electrons 6 of 10 what row in the periodic table is this element with this electronic structure? 2.8.6 the third row as it has 3 outer shells 7 of 10 what is the name of the element with the electronic structure of 2.8.6 Sulphur as it has 16 electrons so the atomic number is 16. 8 of 10 what do all the elements in the same group have in common? the same number of electrons in the outer shell 9 of 10 who were the four people who developed the atomic theory that is accepted today? John Dalton, J.J. Thompson, Rutherford and Bohr 10 of 10
