Group 1 (alkali metals) - PAPER 2 Flashcards
1
Q
Group 1 metals such as potassium, sodium and lithium, react with water to produce
A
a metal hydroxide and hydrogen
2
Q
The observations for the reaction of water with either potassium or sodium or lithium have the following similarities
A
fizzing (hydrogen is produced)
metal floats and moves around on the water
metal disappears
3
Q
as we go down group 1 (increasing atomic number), the elements become
A
more reactive
4
Q
explain the trend in reactivity in Group 1 in terms of electronic configurations
A
As you go down the group the outer electron lost from the group 1 metal is further from the nucleus therefore the electron is less attracted by the nucleus and therefore more easily lost.
