Station Three: Groups And Periods On The Periodic Table

1. The periodic table is often separated into three categories:

Metals, Gases and Liquids

Metals, Organic, and Atoms

Nonmetals, Metals and Metalloids

Metalloids, Plastics and Plasma

The periodic table is organized into three main categories based on the properties of the elements: metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are generally poor conductors and have a variety of properties, such as being brittle and having low melting points. Metalloids have properties that are intermediate between metals and nonmetals. This categorization helps to classify and understand the different elements and their properties.

2. What are the vertical columns on the periodic table called:

Periods

Symbols

Atomic Mass

Groups

The vertical columns on the periodic table are called groups. Each group contains elements that have similar chemical properties and share the same number of valence electrons. The elements within a group often exhibit similar trends in their physical and chemical properties, making it easier to predict their behavior. The groups are numbered from 1 to 18, with the exception of the transition metals in the middle of the table.

3. The term metalliod refers to:

Elements that are 80% metal and 20% nonmetal

Elements can have both characteristics of metals and nonmetals

Elements that have metal characteristics

Elements that have a charged nucleus

The term metalliod refers to elements that can have both characteristics of metals and nonmetals. This means that these elements exhibit properties of both metals and nonmetals, such as being able to conduct electricity like metals but also being brittle like nonmetals. They have intermediate properties between metals and nonmetals, making them unique in terms of their physical and chemical properties.

The term metalliod refers to elements that can have both characteristics of metals and nonmetals. This means that these elements exhibit properties of both metals and nonmetals, such as being able to conduct electricity like metals but also being brittle like nonmetals. They have intermediate properties between metals and nonmetals, making them unique in terms of their physical and chemical properties.

4. The ___________________ are found in the first group of the periodic table. They have the repuatation of being very_____________________.

Alkali Metals, Reactive

Alkaline Earth Metals, Good Conductors

Alkali Metals, Flammable

Transition Metals, Reactive

Alkali Metals are found in the first group of the periodic table. They have the reputation of being very reactive.

Explanation

Alkali Metals are found in the first group of the periodic table. They have the reputation of being very reactive.

5. The rows going across the table are called ______________. The elements in a row all have the same number of _____________.

Periods,Electron Shells

Periods,Protons

Group,Electron Shells

Group, Nuetrons

The rows going across the table are called periods. This is because the elements in each row have the same number of electron shells.

Explanation

The rows going across the table are called periods. This is because the elements in each row have the same number of electron shells.

6. Hydrogen is considered to be an Alkali Metal.

True

False

Hydrogen is considered to be a nonmetal.

Explanation

Hydrogen is considered to be a nonmetal.

7. In what group do you find the non-reactive Noble Gases?

Period 8

Group 7

Group 18

Group 1

The non-reactive Noble Gases are found in Group 18. This group is also known as the "noble gases" or "inert gases" because they are highly stable and do not easily react with other elements. These gases include helium, neon, argon, krypton, xenon, and radon. They have a full outer electron shell, making them very stable and unreactive.

8. Elements in the same group will possess...

Similar Chemical Properties

Similar Physical Properties

The Same Number of Protons

Both A and B

A,B, and C

Elements in the same group of the periodic table exhibit similar chemical properties due to their similar electron configurations. This similarity arises because elements in the same group have the same number of valence electrons, which determines their chemical behavior and reactivity.

Explanation

Elements in the same group of the periodic table exhibit similar chemical properties due to their similar electron configurations. This similarity arises because elements in the same group have the same number of valence electrons, which determines their chemical behavior and reactivity.
