FLASHCARD REVIEW Valence Electrons & Electron Dot Diagrams

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 Calcium (Ca) have?

Back

Calcium has 2 valence electrons.

Front

What is an electron dot diagram?

Back

An electron dot diagram, or Lewis dot structure, represents the valence electrons of an atom as dots around the element's symbol.

Front

How many valence electrons does Bromine (Br) have?

Back

Bromine has 7 valence electrons.

Front

What is the significance of the periodic table in determining valence electrons?

Back

The periodic table organizes elements by groups, where elements in the same group have the same number of valence electrons.

Front

How many dots would an electron dot diagram for Potassium (K) have?

Back

Potassium has 1 dot in its electron dot diagram.

Front

Which elements have similar chemical properties?

Back

Elements in the same group of the periodic table have similar chemical properties due to having the same number of valence electrons.

Front

What is the electron configuration for Beryllium (Be)?

Back

The electron configuration for Beryllium is 1s² 2s², indicating it has 2 valence electrons.

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 structure for Oxygen (O)?

Back

The electron dot structure for Oxygen has 6 dots, representing its 6 valence electrons.
