When 50.0 grams of oxygen are used in the reaction, 25.8 g of nitrogen monoxide are collected in a laboratory. What is the percent yield of the reaction?

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

Where is the following?
