Flashcard - Valence Electrons and Bonding

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

Why do atoms bond?

Back

Atoms bond to achieve a full outer shell of electrons, which makes them more stable.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving stability.

Front

What are noble gases?

Back

Noble gases are elements in Group 18 of the periodic table that are characterized by their lack of reactivity due to having full valence shells.

Front

How many valence electrons does Silicon have?

Back

Silicon has 4 valence electrons.

Front

What happens to electrons in a metallic bond?

Back

In a metallic bond, electrons are shared among a lattice of metal atoms, creating a 'sea of electrons' that allows for conductivity.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons when forming a bond.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between charged ions, while covalent bonds involve the sharing of electrons.
