2a. Group 1 Flashcards
Group 1 Metal + Water
Group 1 Metal (Lithium) + Water -> Group 1 Metal (Lithium) Hydroxide + Hydrogen
Observations when potassium or sodium or lithium reacts
Fizzing
Metal floats and moves around the water
Metal Disappears
As we go down group 1, what happens?
The elements become more reactive
What is an extra observation we can see when potassium reacts?
catches fire with a LILAC flame
What is an extra observation we can see when sodium reacts?
sodium melts into a silver-coloured ball
What is the trend in reactivity in Group 1 in terms of electronic configurations
As you go down the group the outer electron lost from the group 1 is less attracted by the nucleus and therefore more easily lost.
