Path 2 is a straight line because of the alpha particles' O magnetic repulsion
O high velocity
O distance from gold nuclei
O interaction with electrons

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

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

Ok where is the image ?
