Periodic Table - Groups and Periods

Front

What is a Period in the Periodic Table?

Back

A period is a horizontal row in the periodic table, indicating the number of energy shells an element has.

Front

What is a Group in the Periodic Table?

Back

A group is a vertical column in the periodic table, indicating elements that have similar properties and the same number of valence electrons.

Front

Which elements are in Group 12 of the Periodic Table?

Back

Group 12 includes elements like Zinc (Zn), Cadmium (Cd), and Mercury (Hg).

Front

What do elements in the same group have in common?

Back

Elements in the same group have the same number of valence electrons, which leads to similar chemical properties.

Front

What is the significance of the Atomic Number?

Back

The atomic number indicates the number of protons in an atom's nucleus and determines the element's identity.

Front

How do you determine the number of energy shells an element has?

Back

The number of energy shells is determined by the period number in which the element is located.

Front

What are Noble Gases?

Back

Noble gases are elements in Group 18 of the periodic table, known for their lack of reactivity due to having a full valence shell.

Front

What is the difference between metals and nonmetals in the periodic table?

Back

Metals are typically shiny, conductive, and malleable, while nonmetals are dull, insulative, and brittle.

Front

What is the role of valence electrons in chemical bonding?

Back

Valence electrons are involved in forming bonds between atoms, determining how elements interact with each other.

Front

Which two elements have similar properties: Na - Sodium and K - Potassium or He - Helium and Ne - Neon?

Back

Na - Sodium and K - Potassium have similar properties because they are in the same group (Group 1).
