Elements on the left side of the zigzag line on the periodic table are:
Group of answer choices
Metals
Nonmetals
Lanthanides
Gases
Metals
The elements on the left side of the zigzag line on the periodic table are mostly metals. Some common examples of these metals include sodium, magnesium, aluminum, potassium, and calcium.
To determine which elements on the periodic table are on the left side of the zigzag line, you need to understand the arrangement of elements in the periodic table.
The periodic table is divided into several different regions based on the properties of the elements. The zigzag line, also known as the "stair-step line," is a boundary that separates metals from nonmetals on the periodic table.
Elements on the left side of the zigzag line are generally classified as metals. Metals are typically shiny, malleable, and good conductors of heat and electricity. Examples of metals include sodium, magnesium, and iron.
On the other hand, elements on the right side of the zigzag line are generally classified as nonmetals. Nonmetals are typically dull, brittle, and poor conductors of heat and electricity. Examples of nonmetals include oxygen, nitrogen, and sulfur.
Lanthanides are a group of elements that are located at the bottom of the periodic table, usually reserved for separate placement. They are not specifically on the left side of the zigzag line.
Gases, on the other hand, can be found throughout the periodic table and are not exclusive to the left side of the zigzag line.
Therefore, the correct answer to your question is "Metals."
