2022 CHEM FINAL REVIEW Bohr Models and Lewis Dot Diagrams

Front

What is a Bohr model?

Back

A Bohr model is a representation of an atom that depicts electrons orbiting the nucleus in defined paths or energy levels.

Front

What does a Lewis dot diagram represent?

Back

A Lewis dot diagram represents the valence electrons of an atom and how they are arranged in bonds with other atoms.

Front

How many electrons can the first energy level hold in a Bohr model?

Back

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

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the significance of valence electrons?

Back

Valence electrons are important because they determine how an atom can bond with other atoms.

Front

How many valence electrons does carbon (C) have?

Back

Carbon has 4 valence electrons.

Front

What is the correct Lewis dot diagram for neon (Ne)?

Back

Neon has 8 valence electrons, represented as dots around the symbol Ne.

Front

What element has the atomic number 11?

Back

The element with atomic number 11 is sodium (Na).

Front

What is the maximum number of electrons in the second energy level?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What does the term 'isoelectronic' mean?

Back

Isoelectronic refers to different atoms or ions that have the same number of electrons.
