Positive, 1 and Nucleus. 1 of 30 What is the charge, mass and position of Electrons? Negative,1/1835 and Electron shell. 2 of 30 What is the charge, mass and position of Neutrons? Neutral,1 and Nucleus 3 of 30 Why do atoms have no overall charge? Atoms in elements always have equal numbers of protons and electrons and so have no overall charge, because the charges cancel out. 4 of 30 What is an isotope? An isotope is atoms of the same element with a different number of neutrons. 5 of 30 What is an ionic bond? Ionic bonds are chemical bonds formed, by the transfer of electrons, when a metal reacts with a non-metal. 6 of 30 What is electrostatic force? Electrostatic force holds oppositely joined charged ions. 7 of 30 What happens to an atom when it looses an electron? It has a positive charge. 8 of 30 What happens to an atom when it gains an electron? It has a negative charge. 9 of 30 What is an anion? A negative ion (Non metal). Can be found in groups 5+6+7. 10 of 30 What is a cation? A positive ion (Metal). Can be found in groups 1+2. 11 of 30 What is the ionic formula of Sodium?
