Group 1 Flashcards
What happens when lithium reacts with oxygen?
After a few minutes it shines.
What happens when lithium reacts with water?
It fizzes as a gas is being produced. It is an exothermic reaction. The universal indicator turned blue due to the fact that an alkali is present. It floated as it is less dense than the water.
What happens with lithium reacts with chlorine?
It glows brightly and a white solid is left behind.
What happens when sodium reacts with oxygen?
Lose it shine after a few seconds.
What happens when sodium reacts with water?
It fizzes as a gas is being produced it has a yellow flame and steam and is less dense than the water as it floats on top of it. It is also an alkaline.
What happens when sodium reacts with chlorine?
It glows brightly and a white solid is left behind.
What happens when potassium reacts with oxygen?
It loses its shine after a few seconds.
What happens on potassium reacts with water?
It floats on top of the water meaning less dense than water. If fizzes as a gas is being produced. The universal indicator turns blue as an alkaline is present. The reaction happened faster than it did for sodium.
Why does the density increase down group 1?
There are more electron shells that are for the atoms get bigger resulting in them filling more space.
Why does the reactivity increases as you go down group 1?
There are more electron shells meaning the outer electron is further away from the positive nucleus. This means there is a weaker attraction and the outermost electron is most easily lost.
