Bohr Model and Lewis Dot Structure Flashcard (Q1W8)

Front

What is the Bohr Model?

Back

The Bohr Model is a representation of the atom that depicts electrons orbiting the nucleus in defined energy levels.

Front

How many electrons can fit in the 1st energy level of an atom?

Back

2 electrons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

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

Back

The number of valence electrons corresponds to the group number of the element in the periodic table.

Front

What does a Lewis dot structure represent?

Back

A Lewis dot structure represents the valence electrons of an atom as dots around the element's symbol.

Front

How many valence electrons does Lithium (Li) have?

Back

1 valence electron.

Front

How many valence electrons does Magnesium (Mg) have?

Back

2 valence electrons.

Front

What element has 3 valence electrons?

Back

Aluminum (Al) has 3 valence electrons.

Front

What is the maximum number of electrons in the 2nd energy level?

Back

8 electrons.

Front

How would you draw a Lewis dot diagram for an element with 4 valence electrons?

Back

Place 4 dots around the element's symbol, representing each valence electron.
