ChemistryAtomsGCSEAQA Created by: KatieDanielCreated on: 11-02-18 16:50 Atoms Are made up of protons,nuetrons and electrons 1 of 12 Protons Have a positive charge 2 of 12 Electrons Have a negative charge 3 of 12 Neutrons Have no electric charge 4 of 12 Atomic number Is the bottom number of an element and is the number of electrons in an atom of the element 5 of 12 Mass number Is the top number of an element and is the total number of particles in the nucleus of a atom 6 of 12 Ion Is a charged atom 7 of 12 Atoms that gain electrons... Becomes a negative ion because the ion has more negative electrons than positive 8 of 12 Atoms that lose electrons.. Becomes a positive ion because there are more positive ions(protons) 9 of 12 Isotopes Are atoms of the same element with different numbers of neutrons. An example is carbon 10 of 12 Isotopes of an element have different physical properties but... Always have the same chemical properties 11 of 12 How are electrons arranged? They are arranged around the nucleus in shells.1st shell- up to 2 electrons.2nd-up to 8 electrons.3rd & 4th shell-up to 8 electrons 12 of 12
