what happens when group 1 metals react with water?
a metal hydroxide and hydrogen are produced
what can be observed when water is reacted with group 1 metals?
• fizzing (hydrogen is produced) • metal floats and moves around on the water • metal disappears
what can be observed when water is reacted with lithium?
• fizzing (hydrogen gas is released) • lithium floats and moves around on the water • lithium disappears
what can be observed when water is reacted with sodium?
• fizzing (hydrogen gas is released) • sodium floats and moves around on the water • sodium melts into a silver-coloured ball • sodium disappears
what can be observed when water is reacted with potassium?
• fizzing (hydrogen gas is released) • potassium floats and moves around on the water • catches fire with a LILAC flame • potassium disappears
what happens when group 1 metals react with air?
they oxidise
what happens to metling point when going down group 1?
melting point decreases
what happens to density when going down group 1?
density increases
what happens to reactivity when going down group 1?
reactivity increases
