Proton = r.m is 1, r.c is +1 Neutron = r.m s 1, r.c. is 0 Electron = r.m is 0.0005, r.c is -1 State the relative mass and charge of: a. Proton b. Neutron c. Electron The number of protons in the nucleus of an atom. What does the atomic number represent? The number of protons and neutrons n the nucleus of an atom. What does the mass number represent? NO OVERALL CHARGE - the number of protons is equal to the number of electrons. What s the overall charge of an atom? 2,8,8 What is ...

Experiment for Diffusion? - correct answer 1) HCl placed at one end of the test tube, ammonia solution at the other. 2) Where they meet, a ring of Ammonium Chloride appears. 3) The diagram shows that the ammonia is closer to the ring, showing that ammonia must have travelled faster, showing it's a lighter gas. Experiment for Dilution? - correct answer 1) Put a coloured substance in a solvent e.g f...
