Suppose that a nickel filter ia required to produced an intensity ratio of cu k alpha to cu k beta of 100/1 in the filtered beam .calculate the thickness of the filter and the transmission factor for the cu k alpha line,

The chemical bubbles

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
