What element is will have the most similar physical and chemical properties to the element Bromine (Br)?

• Fluorine (F)
• Carbon (C)
• Krypton (Kr)
• Selenium (Se)

Elements that are arranged in __________ have the most similar physical and chemical properties to each other.

• periods
• groups

Periods on the periodic table are __________.

• Horizontal Rows
• Vertical Columns

Groups on the periodic table are __________.

• Horizontal Rows
• Vertical Columns

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
