Electron configuration and introduction to periodic table

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating how electrons are arranged around the nucleus.

Front

What does the periodic table represent?

Back

A tabular arrangement of elements organized by increasing atomic number, showing periodic trends in properties.

Front

What is a group in the periodic table?

Back

A vertical column in the periodic table where elements share similar chemical properties.

Front

What is a period in the periodic table?

Back

A horizontal row in the periodic table that indicates the number of electron shells in the elements.

Front

What are metals?

Back

Elements that are typically shiny, good conductors of heat and electricity, and malleable.

Front

What are nonmetals?

Back

Elements that are generally poor conductors of heat and electricity and can be gases, liquids, or brittle solids.

Front

What is the significance of the atomic number?

Back

It represents the number of protons in an atom's nucleus and determines the element's identity.

Front

How do you determine the group number of an element?

Back

By looking at the number of valence electrons in its outermost shell.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is an atomic orbital?

Back

A region in an atom where there is a high probability of finding electrons.
