The electronic configuration is already known for each of atoms in these questions according to standard tables.
The change that exist in ionization energy that occurs between removing the first and second electrons from an atom is that the <span> ionization energy increases because the ratio of the protons to electrons increases. The answer is letter B.</span>
Having a definite volume but not a definite shape.
Models in science help you get the idea of what something looks like that's why your teacher may ask you to draw a diagram to help you remember what the object looks like.
