Chemical 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

How many valence electrons does Silicon have?

Back

Silicon has 4 valence electrons.

Front

What type of bond forms between two nonmetals?

Back

A covalent bond forms between two or more nonmetals.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that involves the transfer of electrons from one atom to another, resulting in the formation of ions.

Front

Which type of element typically forms positive ions?

Back

Metals typically form positive ions.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be of the same or different elements.

Front

What is electronegativity?

Back

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

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a molecule with a slight charge.

Front

What is a nonpolar covalent bond?

Back

A nonpolar covalent bond is a type of covalent bond where the electrons are shared equally between the two atoms.
