Chemical Bonding

Question 1

Compound

Answer 1

substance made up of 2 or more different elements combined chemically

Question 2

Octet Rule

Answer 2

when bonding occurs atoms tend to reach an arrangement with 8 electrons in outermost energy level

Question 3

Ion

Answer 3

charged atom or group of atoms

Question 4

Ionic Bond

Answer 4

is the force of attraction between oppositely charged ions in a compound. ionic bonds are always formed by the complete transfer of electrons from one atom to another

Question 5

Transition Metal

Answer 5

is one that forms at least one ion with a partially filled d-sublevel

Question 6

Molecule

Answer 6

group of atoms joined together. it is the smallest particle of an element or compound that can exist independently

Question 7

Valency

Answer 7

is the number of atoms of hydrogen or any other monovalent element with which each atom of the element combines

Question 8

Sigma Bond

Answer 8

formed by the head on head overlap of 2 orbitals

Question 9

Pi Bond

Answer 9

formed by the sideways bond of orbitals

Question 10

Electronegativity

Answer 10

the relative attraction that an atom in a molecule has for the shared pair of electrons in a covalent bond

Question 11

Polar Covalent Bond

Answer 11

is a bond in which there is an unequal sharing of the pair(s) of electrons

Question 12

Intramolecular Bonding

Answer 12

the bonding that takes place within a molecule e.g covalent bonding

Question 13

Dipole-Dipole

Answer 13

forces of attraction between the negative pole of one polar molecule and the positive pole of another polar molecule

Question 13

Intermolecular Bonding

Answer 13

are the forces of attraction that exist between molecules from the formation of temporary dipoles

Question 14

Hydrogen Bonds

Answer 14

dipole-dipole bonds which hydrogen is bonded to nitrogen oxygen or fluorine
