1. The Big Three: M, N, & M
What elements on the left and center of the periodic table are known for being shiny and good conductors of electricity?
What are Metals?
This group of non-metals is known as the "salt-formers" and is the most reactive group on the periodic table.
What are Halogens?
These highly reactive metals are located in group 1 of the periodic table.
What are Alkali Metals?
The element Gold (Au), a shiny material often used in jewelry, is classified simply as this broad type of substance.
What is a Metal?
The horizontal rows on the periodic table are called this, and they indicate how many electron shells an element has.
What are Periods?
Found along the "staircase" or zig-zag line, these elements have properties of both metals and non-metals.
What are Metalloids?
The elements in this group are found in Group 18 of the periodic table and are highly stable due to having a full outer electron shell.
What are Noble Gases?
This group is located in Group 2 of the periodic table, and while still reactive, they are less reactive than their Group 1 neighbors.
What are Alkaline Earth Metals?
The element Oxygen (O), vital for human life and breathing, falls into this major classification group.
What is a Non-metal?
The vertical columns on the periodic table are referred to as this, and elements within them share similar chemical properties.
What are Groups (or Families)?
These elements are often dull in appearance, are poor conductors of heat and electricity, and break easily if solid.
What are Non-metals?
At room temperature, every single element in the Noble Gas group exists in this state of matter.
What is a Gas?
Because alkali metals react violently with water and oxygen, they are typically stored under this substance.
What is Oil?
The element Silicon (Si), widely used in computer chips and electronics, is found on the staircase line and belongs to this classification.
What is a Metalloid?
The modern periodic table is organized based on the increase of this specific subatomic particle in an element's nucleus.
What is the Atomic Number?
The physical property that describes the ability of a metal to be hammered into thin sheets without breaking.
What is Malleability?
This specific halogen element is added to toothpaste and municipal water supplies to prevent tooth decay.
What is Fluorine?
All elements in the Alkaline Earth Metals group possess this specific number of valence electrons in their outer shell.
What is Two?
The element Calcium (Ca), found in milk and essential for strong bones, belongs to this specific chemical family in Group 2.
When moving down a group of metals (like the Alkali Metals), the general chemical reactivity follows this trend.
The only element that is a liquid at room temperature while still being classified as a non-metal.
What is Bromine?
This is the main reason why Noble Gases are chemically inert and rarely form compounds with other elements.
What is having 8 valence electrons (or a full outer shell)?
Beryllium and Magnesium are part of this specific "Group Dynamics" classification.
What are Alkaline Earth Metals?
The element Xenon (Xe) is used in some specialized light bulbs because it is very stable and non-reactive, placing it in this "rare" group.
What are Noble Gases?
The number of electrons in an atom's outermost shell, which determines much of its chemical behavior, is called this.
What are Valence Electrons?
