Topic 4. Chemistry A level Edexcel rated ADescribe the trend in ionisation energy down group 2. - decreases because extra
shells are added
- meaning more shielding
- outer electrons are further from the nucleus, weakening the attraction
- meaning the outer electrons is easier to remove
- even though there are more protons, the shielding effect overrides the positive
charge
Describe and explain the trends of atom radius as we go down group 2 - increases
because extra shells are added
What ions do group 2 elements form when they react? - +2
Group 2 react with water to produce?
Give the general equation and the ions in the product - Hydroxides. M(OH)₂
M(s) + 2H₂O(l) → M(OH)₂(aq) + H₂(g)
- M²⁺ ions and OH⁻ ions
Group 2 burn in oxygen to form?
,Topic 4. Chemistry A level Edexcel rated A
Give the general equation and the ions in the product - Oxides MO
2M(s) + O₂ → 2MO(s)
- M²⁺ ions and O²⁻ ions
Group 2 react with chlorine to form?
Give the general equation and the ions in the product - Chlorides, MCl₂
M(s) + Cl₂(g) → MCl₂(s)
- M²⁺ ions and Cl⁻ ions
Magnesium reacts with steam to form?
Give the equation - Magnesium oxide, MgO(s)
Mg(s) + H₂O → MgO(s) + H₂(g)
Explain the trend in reactivity of Group 2 down the group. - Increases
- the higher the ionisation energy the less likely they are to react.
Which group 2 oxide is insoluble. - Beryllium oxide
Group 2 oxides react with H₂O to form?
, Topic 4. Chemistry A level Edexcel rated A
Give the general equation - Hydroxides M(OH)₂
MO(s) + H₂O(l) → M(OH)₂(aq)
Group 2 metals react with dilute hydrochloric acid to form?
give the general equation - MCl₂, and H₂
MO + 2HCl → XCl₂ + H₂
Group 2 metals react with dilute sulfuric acid to form?
give the general equation - MSO₄, H₂
MO + H₂SO₄ → MSO₄ + H₂
Group 2 metals react with dilute nitric acid to form?
give the general equation - M(NO₃)₂, H₂
M + 2HNO₃ → M(NO₃)₂ + H₂
Group 2 oxides react with dilute hydrochloric acid to form?
give the general equation - MCl₂, and H₂O
MO + 2HCl → XCl₂ + H₂O
