D. Matter and energy are the same.
You can use a separating funnel. The person will go the top and the water to the bottom.
Proton number = the atomic number (which is the smaller number
neutron number = the mass number (the bigger number) - the atomic number
number of electrons = the atomic number - the charge (it depends on the element but group 1 is +1 group 2 is +2 group 3 is +3 group five is -3 group six is -2 group seven is -1
i would solve the whole thing but its unclear hope this helps tho
they all have one thing in common and that its all made up of atoms. When these components are active it creates energy
