How many lead atoms are in a cube lead that has a volume of 7.00cm3 if the density of leads is 11.3g/cm3

C: plants and animals

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 is "hydrogen".
