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 fixed paths or energy levels.

Front

What is a Lewis Dot Structure?

Back

A Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

Why are Hydrogen and Helium exceptions to the octet rule?

Back

Hydrogen and Helium are exceptions because they only require 2 electrons in their outermost shell to be stable.

Front

How many valence electrons does Lithium have?

Back

Lithium has 1 valence electron.

Front

What element is represented by the Lewis Dot Structure with 7 dots around it?

Back

Chlorine, which has 7 valence electrons.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the electrons in the outermost shell of an atom and are involved in forming bonds with other atoms.

Front

What does a filled outer shell indicate about an atom?

Back

A filled outer shell indicates that the atom is stable and less likely to react with other atoms.

Front

How many electrons can the first energy level hold?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What is the electron configuration of Argon?

Back

The electron configuration of Argon is 1s² 2s² 2p⁶ 3s² 3p⁶.
