How many grams of lead (II) carbonate are produced when 170 grams of sodium nitrate are also produced by the following unbalanced equation? Pb(NO3)2 + Na2CO3 → PbCO3 + NaNO3

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."
