#1
Front (Question)

how many electrons do they have on their outer shell

Back (Answer)

1

#2
Front (Question)

where are they found

Back (Answer)

group 1

#3
Front (Question)

why do they react in similar ways

Back (Answer)

because they all have 1 electron on their outer shell

#4
Front (Question)

what is the common name for them

Back (Answer)

Alkali metals

#5
Front (Question)

what are the most reactive metals in the periodic table

Back (Answer)

Alkali metals

#6
Front (Question)

physical properties (4)

Back (Answer)

• shiny and silvery • soft • conduct electricity • low melting points

#7
Front (Question)

what sets them apart from other metals (2)

Back (Answer)

much softer, and they have lower melting and boiling points

#8
Front (Question)

melting and boiling points increase as you go

Back (Answer)

UP

#9
Front (Question)

density increases as you go

Back (Answer)

DOWN the group

#10
Front (Question)

group 1 elements react with water and give (2)

Back (Answer)

metal hydroxide and hydrogen

#11
Front (Question)

what happens to lithium when in water and what does that mean

Back (Answer)

it floats and moves around meaning it reacts gently

#12
Front (Question)

what happens to sodium when it reacts with water

Back (Answer)

immediately melts and skims around surface of water reacting quickly

#13
Front (Question)

what happens when potassium reacts with water and what does this mean

Back (Answer)

immediately melts and catches fire (lilac flame), skimming around the surface meaning it reacts vigorously

#14
Front (Question)

metals become ____ reactive down the group

Back (Answer)

MORE

#15
Front (Question)

How do we know that the alkali metals become more reactive down the group

Back (Answer)

by observing how the first three react with water

#16
Front (Question)

potassium burns with what colour flame

Back (Answer)

LILAC

#17
Front (Question)

what is added after you react one of the metals with water

Back (Answer)

universal indicator

#18
Front (Question)

why do you add universal indicator after you react the metals with water

Back (Answer)

it shows that group 1 metals have a pH that is alkaline

#19
Front (Question)

what is the state symbol needed for group 1 hydroxide and why

Back (Answer)

aq because it is soluble

#20
Front (Question)

chemical/symbol equation for the reaction with water ( for potassium for example)

Back (Answer)

2K(aq) + 2H20 (l) + 2KOH (aq) + H2(g)

#21
Front (Question)

they form what solutions when reacting with water (acid or alkali)

Back (Answer)

ALKALI

#22
Front (Question)

other than water, what do they also react with (less strongly)

Back (Answer)

oxygen

#23
Front (Question)

when the metals react, they lose their outer electron and form

Back (Answer)

positive 1+ ions

#24
Front (Question)

what does an electronic configuration show

Back (Answer)

how many electrons there are on each shell
