Water

Question 1

Anion

Answer 1

a negative ion

Question 2

Cation

Answer 2

a positive ion

Question 3

Ionic bonds

Answer 3

bonds formed when atoms give or receive electrons; they result in charged particles called ions

Question 4

Covalent bonds

Answer 4

bonds formed when atoms share electrons; covalent molecules may be polar if the electrons are not shared evenly

Question 5

dipole

Answer 5

the separation of charge in a molecule when the electrons in a covalent bond are not evenly shared

Question 6

polarised

Answer 6

when electrons in a covalent bond are not quite evenly shared

Question 7

Polar molecule

Answer 7

a molecule containing a dipole

Question 8

Dissociation

Answer 8

splitting of a molecule into smaller molecules, atoms or ions, especially by a reversible process

Question 9

Hydrogen bonds

Answer 9

weak electrostatic intermolecular bonds formed between polar molecules containing at least one hydrogen atom

Question 10

Polar solvent

Answer 10

is a solvent that has large dipole moments. The molecules in the solvent are polar because of the different electronegativity values. A polar solvent can dissolve ions and other polar compounds

Question 11

Cohesion

Answer 11

the act, state, or process of sticking together of alike molecules or entities. (the attraction of molecules of other molecules of the same kind)

Question 12

Adhesion

Answer 12

the attraction of molecules of one kind to molecules of a different kind
