Chem Vocab

Chemical Bond

• Hold Opposite charger partícula together

• Force that holds 2 atoms together

• Chemical bond sharing valance electrons

• Electrons are shared equaly

Ionic Bond

• Made of ions

• Anion of 1 or more Oxygens

• Holds oppositely Charged Particles together

• Chemical Bond sharing VALANCE electrons

Diatomic Molecule

(Hint: “Di” means 2)

• ELECTRONS shared equally

• 2 atoms in a Chemical Bond

• 3+ elements in a bond

• Attraction between opposite forces

Covalent Bond

(HINT: “Co” means together/shared)

• Sum of atomic masses together

• Electrons are NOT shared

• 2+ NONMETAL atoms in a shared Bond

• A chemical bond sharing Valance Electrons

Nonpolar covalent bond

(HINT: “Co” means together/shared)

• Force that holds 2 atoms together

• Electrons are shared equally

• Holds oppositely charged particles together

• Holds the molecule together (it holds together the CH and the O together in CHO)

Polar Covalent Bond

(HINT: “Co” means together/shared)

• Electrons are NOT shared

• A formula that solves the # of atoms

• Force in-between the individual attractions (if the formula is HCL2 it holds together the H and CL)

• 2+ Atoms bonded

Delocalized Electrons

• % version of the mass

• 2+ NONMETAL atoms in a Covalent Bond

• Ratios of different atoms

• Electrons involved in metallic bonding and can move freely through the metal

Intramolecular Forces

• Attraction between opposite forces

• Force in between the the attraction (like between the H and the Cl in HCl)

• Hold the molecule together (such as the space between the HCl and the HCl

• Made of ions

Molecular Formula

• Formula that solves the # of atoms

• Ratios of different atoms (NO2 = 1:2)

• Sum of atomic masses

• Force that holds 2+ atoms together

Intermolecular Forces

• Force in between (what holds the H and Cl together in HCl

• 2+ atoms bonded

• Hold the whole molecule together (like the 2 HCl’s in HCl2)

• Anion; one or more oxygens
