Group 1 - The Alkali Metals Flashcards
(8 cards)
how do lithium, sodium and potassium react with water?
vigorously
what solution is made when group 1 metals react with water?
a metal hydroxide solution - this is an alkaline solution (hence why group 1 metals are called alkali metals)
what does the reaction of group 1 metals with water produce?
hydrogen - this is why there is fizzing
what do group 1 metals form when they react with oxygen?
metal oxides
what type of oxide forms when lithium reacts with oxygen?
lithium oxide (Li2O)
what type of oxide forms when sodium reacts with oxygen?
a mixture of sodium oxide (Na2O) and sodium peroxide (Na2O2)
what type of oxide forms when potassium reacts with oxygen?
a mixture of potassium peroxide (K2O2) and potassium superoxide (KO2)
as you go down group 1 the elements become more…
