Electron Dot Diagrams

Front

What is an Electron Dot Diagram?

Back

An Electron Dot Diagram, also known as a Lewis Dot Diagram, is a representation of the valence electrons of an atom, depicted as dots around the element's symbol.

Front

What do valence electrons determine?

Back

Valence electrons determine an atom's chemical properties and its ability to bond with other atoms.

Front

How many valence electrons does Neon (Ne) have?

Back

Neon has 8 valence electrons.

Front

What is the significance of the octet rule in Electron Dot Diagrams?

Back

The octet rule states that atoms tend to bond in such a way that they have 8 electrons in their valence shell, achieving a stable electron configuration.

Front

Which group of the periodic table contains elements with a full valence shell?

Back

Group 18 (Noble gases) contains elements with a full valence shell.

Front

What is the valence electron configuration for Magnesium (Mg)?

Back

Magnesium has 2 valence electrons, represented as '2' in its outermost shell.

Front

How do you represent a single bond in an Electron Dot Diagram?

Back

A single bond is represented by a pair of dots or a line between two atoms, indicating that they share one pair of electrons.

Front

What is the difference between a Lewis Dot Diagram and a structural formula?

Back

A Lewis Dot Diagram shows only the valence electrons, while a structural formula shows the arrangement of atoms and the bonds between them.

Front

What element is stable with only 2 valence electrons?

Back

Helium is stable with only 2 valence electrons.

Front

How many valence electrons do elements in the same group of the periodic table have?

Back

Elements in the same group have the same number of valence electrons.
