Ch. 5 Electron Dot Diagrams

Front

What are Electron Dot Diagrams?

Back

Electron Dot Diagrams are visual representations of the valence electrons in an atom, showing how they are arranged around the atomic symbol.

Front

What is the significance of Group 18 in the periodic table?

Back

Group 18 contains noble gases, which have stable valence electron configurations and are generally unreactive.

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 many valence electrons does phosphorus (P) have?

Back

Phosphorus has 5 valence electrons.

Front

Which group of elements is known for having a full outer shell?

Back

Group 18 (Noble gases) is known for having a full outer shell.

Front

What is the electron configuration of sodium (Na)?

Back

The electron configuration of sodium is 1s² 2s² 2p⁶ 3s¹.

Front

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

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is the electron dot diagram for sodium (Na)?

Back

The electron dot diagram for sodium shows one dot representing its one valence electron.

Front

Why are noble gases considered stable?

Back

Noble gases are considered stable because they have a complete outer shell of electrons, making them less likely to react.

Front

What is the electron dot diagram for phosphorus (P)?

Back

The electron dot diagram for phosphorus shows five dots around the symbol 'P', representing its five valence electrons.
