Which element's atom is larger? Nitrogen or Phosphorus?
Nitrogen
Phosphorus
Which element's atom is the smallest?
Rhodium
Silver
Cadmium
Tin
Which of these best explains the reasoning behind the trend that as you go across a period, size decreases?
As you go across a period, more energy levels are added, which shrinks the atom.
The added electrons in the nucleus give the atom a negative charge, which shrinks the atom.
The added protons in the nucleus pull the electrons closer to them, which shrinks the atom.
All of the above
