Group Chemistry

Question 1

What are g1 like

Answer 1

Highly reactive and metal is electron donors producing cations

Question 2

G1 physical properties

Answer 2

Soft and having for metals relatively low melting and boiling points

Question 3

Why store under oil with moist air?

Answer 3

Reaction with air and water. … Alkali metals need to be stored under oil to prevent them reacting with the oxygen and water vapour in the air. The reactivity of the alkali metals increases down the group. Potassium reacts more vigorously than sodium and lithium is the least reactive

Question 4

How does reactivity work down group 1

Answer 4

It increase

Question 5

What happens when metals react with water?

Answer 5

Oh and h2 gas

Question 6

What happens when o2 reacts with metals?

Answer 6

Oxides

Question 7

Metals and group 17

Answer 7

Eg NaCl

Question 8

Define non metals

Answer 8

Acceptors of electrons so forming anions

Question 9

What are the most reactive non metals

Answer 9

Halogens

Question 10

How does halogens reactivity go down the group

Answer 10

Decrease

Question 11

Test for ions halide

Answer 11

Silver nitrate solution
Cl white
Br cream
I yellow

Question 12

What three properties of transition metals

Answer 12

Form different stable ions in different conditions
Form coloured compounds
Used as catalyst as ions or atoms
