Flashcards in Bonding and Structure Deck (10):
1

define ionic bonding

electrostatic attraction between positive and negative ions

2

define a covalent bond

the strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms

3

what is a dative covalent bond?

a shared pair of electrons with the electrons being provided by one of the atoms (e.g. NH4+)

4

what is average bond enthalpy?

the average enthalpy change which
takes place when breaking by homolytic fission one mole of a given
type of bond in the molecules of a gaseous species

5

a dimer is ..

covalent

6

define giant

continuous structure in 3D

7

define metallic bonding

electrostatic attraction between positive metal ions and delocalised electrons

8

why are metals insoluble in water?

too much energy is required to break the strong electrostatic forces

9

define malleable

can easily be bent in to different shapes

10

define ductile

can be drawn in to a wire
