Question

color coding the periodic table student worksheet part 2: answer the questions. 1. the vertical columns on the periodic table are called __________ 2. the horizontal rows on the periodic table are called ________ 3. most of the elements in the periodic table are classified as ________ 4. the elements that touch the zigzag line are classified as ________ 5. the elements on the right side of the periodic table are classified as________ 6. elements in the first group are extremely reactive. they are called ________ 7. elements in the second group are also very reactive. they are called ________ 8. elements in groups 3 through 12 have many useful properties and are called ________ 9. elements in group 17 are known as \salt formers\. they are called ________ 10. elements in group 18 are very unreactive. they are said to be \inert\. we call these the __________

Explanation:

1. The vertical columns on the periodic table are called groups or families. This is a standard term in chemistry for elements with similar chemical properties.
2. The horizontal rows are called periods. Elements in a period have the same number of electron - shells.
3. Most elements are metals. Metals are typically good conductors of heat and electricity and have a shiny appearance.
4. Elements touching the zig - zag line are metalloids. They have properties intermediate between metals and non - metals.
5. Elements on the right side are non - metals. Non - metals have properties opposite to those of metals, such as being poor conductors.
6. Elements in the first group are alkali metals. They are highly reactive due to having one valence electron.
7. Elements in the second group are alkaline earth metals. They are also reactive but less so than alkali metals.
8. Elements in groups 3 - 12 are transition metals. They have variable oxidation states and many useful properties like catalytic activity.
9. Elements in group 17 are halogens. They readily form salts with metals.
10. Elements in group 18 are noble gases. They have a full outer electron shell, making them very stable and unreactive.
