In the periodic table, similar elements are arranged in vertical columns called groups. Some of the major groups include Group 1: alkali metals; Group 2: alkaline earth metals; Group 17: halogens; and Group 18: noble gases. Elements within each group have similar properties and characteristic behaviors because of their similar numbers of valence electrons.
In what direction are groups arranged in the periodic table?
Side to side
Up and down.
Diagonally
In sections.
The periodic table is further arranged into three major regions, including the metals, metalloids, and non-metals. Metals are on the left of the table; they are shiny and flexible, conduct heat and electricity, and participate in ionic reactions. Non-metals are on the far right of the table; they are dull and brittle, are poor conductors, and typically participate in ionic reactions.
Which one is NOT a major region of elements in the periodic table?
Metals
Mettaloids
Non metals
Gases
What do the vertical columns on the periodic table tell us?
The number of orbitals
The number of valence electrons (electrons on the outer most shell)

Why are both hydrogen and cesium s-block elements, when hydrogen has one electron and cesium has 55?
All blocks contain at least one element from each period.
Blocks of elements on the periodic table are based only on an element's valence electrons.
The s-block includes only the most reactive elements.
They have identical electron configurations.
