In the nucleus 6 of 13 Define mass number the total number of protons and nuetrons in an atom 7 of 13 Define relative atomic mass The ratio of the average mass of one atom of an element to one twelfth of the mass of a carbon-12 atom 8 of 13 Define atomic number The number of protons in the nucleus which identifies the atom. 9 of 13 What is an ion? A charged particle. 10 of 13 What is an isotope? elements with different numbers of neutrons in the nucleus 11 of 13 What is it that has an effect on the chemical reactions of an element? the electronic configuration 12 of 13 Why is it that isotopes have similar chemical reactions but different physical properties? because they have the same electronic configuration, but the mass of the isotopes are different so they will have different physcical properties 13 of 13
