Back

An atom in period 2 has two energy levels.

Front

What does the group number in the periodic table indicate?

Back

The group number indicates the number of valence electrons in the outermost shell of an atom.

Front

What is the period for the element Bromine (Br)?

Back

The period for Bromine is 4.

Front

What is the relationship between periods and energy levels?

Back

The period number corresponds to the number of energy levels in an atom.

Front

What is a characteristic property of metals?

Back

Metals are malleable, meaning they can be hammered or rolled into thin sheets.

Front

What is the group number for elements that have similar chemical properties?

Back

Elements in the same group have similar chemical properties due to having the same number of valence electrons.

Front

How can you determine the number of valence electrons in an element?

Back

You can determine the number of valence electrons by looking at the group number of the element in the periodic table.

Front

What is the difference between a period and a group in the periodic table?

Back

A period is a horizontal row indicating energy levels, while a group is a vertical column indicating elements with similar properties.

Front

What is the significance of the atomic number in the periodic table?

Back

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