What does the ratio of volume of water in beakers a& b at equilibrium represent compared to chemical reactions?

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom

The correct answer should be "electrons orbit the nucleus in circular motions exactly as shown on the classic bohr model."
