How many liters of nh3, at stp, will react with 5.3 g o2 to form no2 and water? 4nh3(g) + 7o2(g) -> 4no2 + 6h2o(g)?

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
