False Statements on the Periodic Table
Chapter 11, Problem 116(choose chapter or problem)
Which of the following statements about the periodic table is false?
a. Elements in the same column have similar reactivities because their valence electrons tend to be located in the same types of orbitals.
b. A series of ions that are isoelectronic (contain the same number of electrons) in their ground states must have the same electron configuration.
c. The atomic size of the elements increases going across a period from left to right because the number of electrons increases, so the electrons are located further from the nucleus.
d. It takes more energy to remove an electron from lithium than from cesium because the valence electrons in lithium are located closer to the nucleus.

ANSWER:Step 1 of 3
Periodic trends in the periodic table involve electronegativity, ionization energy, electron affinity, atomic radius, melting point, metallic character, etc.
It comes from the way by which the elements are arranged in the periodic table.
