Front

What are valence electrons?

Back

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

Front

What is the Lewis Dot Structure for oxygen (O)?

Back

The Lewis Dot Structure for oxygen has 6 dots representing its 6 valence electrons.

Front

What is the significance of having 8 valence electrons?

Back

Having 8 valence electrons (octet) generally makes an atom more stable and less reactive.

Front

Which element has 5 valence electrons?

Back

Phosphorus (P) has 5 valence electrons.

Front

What is the Bohr model of an atom?

Back

The Bohr model depicts an atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus.

How many valence electrons does neon (Ne) have?

Back

8

Front

What are transition elements?

Back

Transition elements are the elements found in groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states and colored compounds.
