What are the rows of the periodic table called?
Periods
1 of 8
What are elements arranged in order of? (Example)
In order of increasing atomic number along each row. E.g, the atomic numbers of the Period 2 elements increase from 3 for Li to 10 for Ne.
2 of 8
What is the period number the same as? (Example)
The period number is the same as the number of electron shells. E.g, the Period 3 elements have 3 electron shells.
3 of 8
What happens to the properties of elements as you go along a period?
They change (sometimes quite dramatically).
4 of 8
What are the columns of the periodic table called?
Groups
5 of 8
What do elements in the same group have and why?
Similar properties, as they have the same number of electrons in their outer shell.
6 of 8
What is the group number always equal to? (Example)
The number of electrons in the outer shell. E.g, the Group 2 elements all have two electrons in their outer shell.
7 of 8
What do the properties of elements (such as reactivity) often do?
They often gradually change as you go down a group (as the atomic number increases)
