Front (Question)

State the number of electrons that can fill the first four shells

Back (Answer)

Front (Question)

Shape of s-orbitals

Back (Answer)

• Spherical shape

Front (Question)

Shape of p-orbitals

Back (Answer)

• 3D dumb-bell shape

Front (Question)

How many electrons can an s-orbital hold?

Back (Answer)

Front (Question)

How many electrons can a p-orbital hold?

Back (Answer)

Front (Question)

How many electrons can a d-orbital hold?

Back (Answer)

Front (Question)

Which shells contain s-orbitals?

Back (Answer)

• All shells

Front (Question)

Which shells contain p-orbitals?

Back (Answer)

• From n=2 upwards

Front (Question)

Which shells contain d-orbitals?

Back (Answer)

• From n=3 upwards

#10

Front (Question)

Does 4s or 3d have a higher energy level?

Back (Answer)

• 3d has a higher energy level so is filled first

#11

Front (Question)

Define ionic bonding

Back (Answer)

• The electrostatic attraction between positive and negative ions

#12

Front (Question)

Describe giant ionic lattice structure

Back (Answer)

• Repeating pattern of oppositely charged ions with strong electrostatic attraction in all directions

#13

Front (Question)

Explain the melting/boiling point of a giant ionic lattice

Back (Answer)

• Strong ionic bonds in all directions means lots of energy needed to overcome these bonds, so has a high mp/bp

#14

Front (Question)

Explain the electrical conductivity of a giant ionic lattice

Back (Answer)

• Giant ionic lattices can only conduct when melted/dissolved because ions are not mobile/cant move in the solid state

#15

Front (Question)

Explain the solubility of a giant ionic lattice

Back (Answer)

• Giant ionic lattices are soluble in polar solvents (e.g water) because polar water molecules can interact/break apart the ions

#16

Front (Question)

Define covalent bonding

Back (Answer)

• The strong electrostatic attraction between a shared pair of electrons and the nucleus of the bonded atoms

#17

Front (Question)

Define dative covalent bonding

Back (Answer)

• When one atom provides both of the shared electrons in a covalent bond

#18

Front (Question)

What type of bonding does average bond enthalpy measure?

Back (Answer)

• Covalent bond

#19

Front (Question)

Compare the relative repulsion strengths of bonded pairs of electrons and lone pairs of electrons

Back (Answer)

• Lone pair repulsion is greater than bonded pair repulsion

#20

Front (Question)

Draw the shape and bond angle of a linear molecule.

Back (Answer)

#21

Front (Question)

Draw the shape and bond angle of a non-linear molecule.

Back (Answer)

#22

Front (Question)

Draw the shape and bond angle of a trigonal planar molecule.

Back (Answer)

#23

Front (Question)

Draw the shape and bond angle of a pyramidal molecule.

Back (Answer)

#24

Front (Question)
