does it have multiple choice
Answer:
Each row is called a period. Each column is called a group or family.
Explanation:
Sodium (Na) and Argon (Ar) on the periodic table does not have similar properties.
PERIODIC TABLE:
- Periodic table is the organized table that showcases the position of elements. The periodic table is organized into groups and periods.
- Groups of the periodic table is in a vertical format labeled 1 - 7 while the period is in a horizontal format labeled 1 - 7.
- Elements in the same group have the same number of valence electrons and hence, possess similar chemical properties.
- Sodium (Na) belongs to group 1 while argon is a noble gas, hence, they are not in the same group of the periodic table and cannot have same properties.

The element which is least likely to undergo a chemical reaction is (4) neon.
The reason for this is because neon is a noble gas, which means that it doesn't react with other elements as well.
