1. The three major groups on the Periodic Table are the metals, nonmetals, and metalloids. Elements within each group have similar physical properties and chemical properties.

The periodic table is broadly divided into these three categories based on shared physical and chemical traits.

2. Physical Properties:

• Luster = the ability of a substance to reflect light. Usually the descriptive words are either metallic (shiny) or non - metallic (dull).

Luster describes how light interacts with a substance’s surface; metals are typically shiny, nonmetals dull.

• Conductivity = the ability of the substance to conduct heat and electricity. This may be tested with a conductivity meter.

Conductivity measures how well a substance transmits energy (heat/electricity); metals are good conductors, nonmetals poor.

• Malleability = the ability of the substance to be hammered into sheets without breaking.

Answer:

Malleability (e.g., aluminum foil production) is core to metal behavior.

Final Answers (Filled Blanks):

1. The three major groups on the Periodic Table are the $\boldsymbol{\text{metals}}$, $\boldsymbol{\text{nonmetals}}$, and $\boldsymbol{\text{metalloids}}$. Elements within each group have similar $\boldsymbol{\text{physical properties}}$ and chemical properties.
2. - $\boldsymbol{\text{Luster}}$ = the ability of a substance to reflect light. Usually the descriptive words are either $\boldsymbol{\text{metallic (shiny)}}$ or $\boldsymbol{\text{non - metallic (dull)}}$.

• $\boldsymbol{\text{Conductivity}}$ = the ability of the substance to conduct $\boldsymbol{\text{heat and electricity}}$. This may be tested with a conductivity meter.
• $\boldsymbol{\text{Malleability}}$ = the ability of the substance to be $\boldsymbol{\text{hammered}}$ into sheets without breaking.
• $\boldsymbol{\text{Ductility}}$ = the ability of the substance to be pulled into a $\boldsymbol{\text{wire}}$.

1. - Found to the $\boldsymbol{\text{left}}$ of the zigzag line on the periodic table.

• $\boldsymbol{\text{Solid}}$ at room temperature, except for $\boldsymbol{\text{mercury (Hg)}}$, which is a liquid.
• $\boldsymbol{\text{Good}}$ conductors of electricity and $\boldsymbol{\text{heat}}$. But some are better conductors than others!
• Metallic looking with a $\boldsymbol{\text{metallic luster (shiny)}}$.
• $\boldsymbol{\text{Ductile}}$ and can be drawn into wire, but some metals are more ductile than others.
• $\boldsymbol{\text{Malleable}}$ and can be hammered into sheets without breaking.
