Concept 1: Intro to Bonding

Front

What is the primary difference between the forces between different substances and the forces within a substance?

Back

Forces between different substances are weaker than forces within a substance.

Front

What can a chemical formula tell you about a compound?

Back

A chemical formula tells you the elements and their ratios, and you can predict properties like melting point and solubility based on the bonds.

How can you identify a bond or a compound as ionic or covalent based on electronegativity differences?

Back

If the electronegativity difference is large, the bond is ionic.

Front

Why do most atoms form chemical bonds?

Back

Most atoms form bonds to achieve a full outer electron shell, while noble gases already have full shells.

How can an element's location on the periodic table help predict its oxidation number?

Back

Elements in the same group have similar oxidation numbers and bonding tendencies.

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell.

What are valence electrons?

Back

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