#1
Front (Question)

whats the trend in atomic radius down the group?

Back (Answer)

• increases • electron number increases so the number of shells do

#2
Front (Question)

whats the trend in I.E down the group?

Back (Answer)

• decreases • shielding increases and electrons become further away from the nucleus

#3
Front (Question)

whats the trend in mpt down the group?

Back (Answer)

• decreases electrons get further away from the positive nucleui as atoms get bigger, less attraction between, metal ions and delocalised electrons

#4
Front (Question)

whats the trend in reactivity with water down the group?

Back (Answer)

• increases 2 electrons are lost more easily from Ba than Ca as the outer electrons are further from the nucleus and experience more shielding, so attraction decreases

#5
Front (Question)

whats the trend in solubility down the group with metal hydroxides?

Back (Answer)

• increases • Mg0H2 is insoluble Ca and Mg are solids others are aqueous

#6
Front (Question)

whats the trend in solubilty down the group with metal sulphates?

Back (Answer)

• decreases • Mg is the only aqueos one rest are solids • Sr, Ba, Ra are insoluble

#7
Front (Question)

what is observed in Mg, Ca, Sr, Bacl2 when reacted with NaOH?

Back (Answer)

mg + ca = white percipitate ba + sr = colourless solution

#8
Front (Question)

what is observed in Mg, Ca, Sr, Bacl2 when reacted with H2SO4?

Back (Answer)

mg + ca = colourless solution sr + ba = white percipitate

#9
Front (Question)

what do u add to test for sulphates?

Back (Answer)

add HCL + BaCl2

#10
Front (Question)

what is Mg(OH)2 used for?

Back (Answer)

neutralises stomach acid
