Flashcards in Topic 6 - Groups In The Periodic Table Deck (15):
1

Properties of alkali metals

Low Melting point
Very soft

2

Group 1 reactivity

Readily lose single electron.
As atomic radii increases with shielding its attraction to the nuclei decreases.

3

Alkali metal + cold water.

Hydroxide + Hydrogen

4

Chlorine properties

Toxic, green gas

5

Bromine reactions

Toxic
Red-brown liquid and gives off orange vapour

6

Iodine

Grey solid, purple vapour

7

Test for chlorine

Damp blue litmus paper is bleached. (May turn red as it is acidic)

8

Reactivity and halogens

Lower radii gives a greater attraction to attract electrons.

9

Halogens + metal

Metal halide (salt)

10

Halogen + Hydrogen

Hydrogen Halide (salt)

11

Displacement and halogens

More reactive will displace.

12

Features of a noble gas

Inert, colourless, non-flammable, hard to observe

13

Precipitation reaction

Take 2 transparent solutions. Mix the 2. Until a mark on paper is no longer visible time it.

14

Reaction rate in change of mass

Using a mass balance. Time when the mass stops changing.

15

Reaction rate from gas release

Collect gas over a given time interval. The reaction ends once it stops changing
