Wo different atoms have four protons each and the same mass. However, one has a positive charge while the other is neutral. Describe what each atomic structure could be, listing the possible number and location of all subatomic particles

Fission of uranium-235 products energy and a. isotopes of smaller elements b. isotopes of larger elements c. lighter isotopes of uranium d. heavier isotopes of uranium

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →

As changes in energy levels of electrons increase, the frequencies of atomic line spectra they emit
