They have the same outer shell electron configuration.
They have similar periodic properties.
They are all solids, or all liquids or all gases.

The diagram shows the electron structures of two alkali metals and two halogens. When these elements react and form compounds, alkali metals lose their one valence electron while halogens gain one additional electron to their valence shell. The vigor of the reaction is directly related to the distance of the valence electrons from the attractive pull of the atom’s nucleus. For alkali metals, it becomes easier to lose the valence electron with increasing distance of that electron from the attractive pull of the nucleus. For halogens, it becomes easier to gain an additional electron to the valence shell with decreasing distance of that shell to the attractive pull of the atom’s nucleus.

The labels on two bottles of powdered metals have fallen off. From the labels, the metals are known to be Mg and Ca. Your friend Jace says it is possible to determine which label should go on which bottle by observing the reaction between small amounts of each metal in separate beakers containing equal quantities of water.
Considering particles at the subatomic level, carrying out this experiment would help to identify the metals given that:
Ca has the (smaller/larger) atomic radius. In chemical reactions, it would be (easier/harder) for it to lose its valence electrons to form ions. This means it has comparatively (lower/higher) ionization energies and would react more (slowly/quickly) with the water.
Which list of words correctly completes (from left to right) the passage?
smaller; easier; higher; quickly
larger; easier; lower; quickly
smaller; harder; higher; slowly
larger; harder; lower; slowly
