  Valence electronsHydrogen: $1 s^{1}$ , $1$ valence electron. Carbon: $[He] 2 s^{2} 2 p^{2}$ , $4$ valence electrons.
  1 mark · Draw Lewis diagrams
2. ✓
  Lewis diagramCarbon in the centre shares one pair with each of the four H atoms (each pair one dot and one cross), see diagram.
  1 mark · Draw Lewis diagrams
3. Question WE3 · Siyavula Grade 10 Physical Sciences, 2.4 Names and formulae of substances, Worked example 3 · 3 marks
WE3 What is the formula of sodium fluoride?(3)
Show the memo (3 ticks)Memo
1. ✓
  IonsSodium ion $Na^{+}$ and fluoride ion $F^{-}$
  1 mark · Write names and formulae of compounds
2. ✓
  RatioThe $+ 1$ from sodium cancels the $- 1$ from fluoride, so they combine in a $1 : 1$ ratio.
  1 mark · Write names and formulae of compounds
3. ✓
  Formula $NaF$
  1 mark · Write names and formulae of compounds
4. Question 3.2 · May/June 2024 · Paper 2 · National (DBE) · 1 mark
The boiling points of some organic compounds are shown in the table below. The atmospheric pressure is $101, 3$ kPa.

Show the memo (1 tick)Memo
1. ✓
  Liquid at 100 °CC
  1 mark · Explain phase changes with particles
5. Question WE1 · Siyavula Grade 10 Physical Sciences, 4.4 Structure of the atom, Worked example 1 · 4 marks
WE1 Use standard notation to represent sodium and give the number of protons, neutrons and electrons in the element.(4)
Show the memo (4 ticks)Memo
1. ✓
  ProtonsSymbol $Na$ . Sodium has $11$ protons ( $Z = 11$ ).
  1 mark · Find protons, neutrons and electrons
2. ✓
  ElectronsSodium is neutral, so it has the same number of electrons as protons: $11$ electrons.
  1 mark · Find protons, neutrons and electrons
3. ✓
  Mass number and neutronsFrom the periodic table $A = 23$ .
  $N = A - Z = 23 - 11 = 12$ neutrons
  1 mark · Find protons, neutrons and electrons
4. ✓
