The Periodic Table Flashcards
What do you call vertical columns on the periodic table
Groups
What are horizontal rows called on the periodic table
Periods
What can we say about the group number and the electrons in the outer shell
The group number is the same as the number of electrons in the outer shell
What does the period number tell us about the shell
The period number is the number of shells of electrons there are
E.g
Group 7 ( bromine ) group 7 Therefore 7 electrons in outer shell
What does group one contains on the periodic table
The most reactive metals
What are group one metals called
Alkali metals
As we go down group one the metals get what
Get more reactive
How many electrons are in the outer shell in group one
One electron
Group 7 contains the most reactive what
The most reactive non-metals
What are the group 7 elements know as
Halogens
How many electrons are there in the outer shell in group 7
There are 7 electrons in the outer shell
And we go down group 7 the non-metal get what
Less reactive
What is group 8 know as
The noble
What are all the group 8 elements
Unreactive non-metals
Why do they not react
They have a full outer shell of electrons
