Definitions- Ionic bonding up to electrons (first 7 powerpoints)

Question 1

Electrostatic attraction

Answer 1

The attraction between a positive and negative ion, causing them to stay together, as in ionic bonding

Question 2

Isoelectronic

Answer 2

having the same electronic structure as another element

Question 3

Daitive coordinate bond

Answer 3

A bond where one atom/ ion doesn’t bring any electrons to the pair e.g. when an ammonia molecule gains a hydrogen ion/proton. —->

Question 4

Electron deficiency

Answer 4

where an atoms outer shell is not full e.g. BF3

Question 5

Valence shell electron pair repulsion theory

Answer 5

molecules take up the shape that minimises repulsion between electron pairs within the molecule

Question 6

Electronegativity

Answer 6

the ability of an atom in a covalent bond to attract the shared bonded pair of electrons

Question 7

Polar bond

Answer 7

a covalent bond where there is a separation of charges. one atom is more electronegative than the other so it attracts the shared pair of electrons more than the other atom

Question 8

Polar molecule

Answer 8

a molecule with two poles (positive and negative)

Question 9

Permanent dipole dipole attraction

Answer 9

the attraction between two polar molecules

Question 10

Intermolecular forces

Answer 10

attractions between one molecule and another

Question 11

Hydrogen bonding

Answer 11

where theres a hydrogen atom attached to an oxygen, nitrogen and fluorine atom, and a lone pair of electrons present— strong type of permanent dipole attraction
