Question

1. If you have a Periodic Table that is NOT color coded, describe WHERE to look on the Periodic Table to find elements which have similar chemical properties. 2. Explain WHY they have similar chemical properties then name three elements that have those similarities.

Answer 1

1. The columns
2. They have close to the same number of valliance electrons
Neon Argon Krypton

Answer 2

Step-by-step explanation:

When a periodic table is not color coded then we can find the elements with same chemical properties in a column.

This is because elements present in a column have same number of valence electrons and it is the valence electrons which help in determining the chemical reactivity and other properties of an element.

For example, chlorine, bromine, and iodine are all group 17 elements and they show similar chemical properties.
