Verified Answers
Give the full electron configuration of the element in period 3 with
the highest first ionisation energy. - ✔✔✔ANSWER-1s2 2s2 2p6 3p6
Give an equation, including state symbols to represent the process that
occurs when the second ionisation energy of sodium is measured. -
✔✔✔ANSWER-Na⁺(g) → Na²⁺(g) + e⁻
, Describe the structure and bonding in magnesium - ✔✔✔ANSWER-It
is a lattice of Mg²⁺ ions held together by their attraction for a 'sea' of
delocalised electrons.
State the trend in the atomic radius of the elements down Group 2 from
Mg to Ba. Give a reason for this trend. - ✔✔✔ANSWER-Trend: Increases
Reason: Each successive element has an additional shell of electrons.
Give an equation, including state symbols, for the reaction of
magnesium with steam. State two observations from this reaction. -
✔✔✔ANSWER-Equation:
Mg(s) + H₂O(g)→MgO(s) + H₂(g)
Observation 1: bright white flame
Observation 2: white solid residue formed
The sulphates of elements in Group 2 from Mg to Ba have different
solubilities. State the formula of the least soluble of these sulphates.
Give a use for this sulphate. - ✔✔✔ANSWER-Formula: BaSO₄
Use: barium meal for x-rays
A mixture of gases is analysed using TOF mass spectrometry.
The mixture contains argon, carbon dioxide, nitrogen and oxygen.
