What is the outer electron configuration for all group 1 elements?
1
Why are elements like neon and argon unreactive?
Because they already have a full outer shell of electrons, which is the most stable configuration.
What do elements in each group have in common?
Electron configuration - they have the same number of elements in their outer 'electron shell'. This induces them to have similar bonding properties, and so elements in the same group are chemically similar.
What do elements in the periodic table in the same column have in commin?
The same number of electrons IN THEIR OUTER SHELL. Look up electron configuration for more detail.
Write the outer electron configuration for oxygen?
2s22p4
What is the outer electron configuration for all group 1 elements?
1
What is distinctive about the electronic configuration of the group 2 elements?
They all have 2 electrons in their outer shells.
How can the periodic table help scientist infer the properties of these elements?
Periodic table was constructed by using electronic configuration . Elements have same outer shell electronic configuration were in same group . So they have similar chemical properties . If an unknown element will register in future , its properties are predicted with the help of its outer shell configuration.

Electrons configuration for group18?
Group 18 elements all have an outer shell of 8 electrons, s2 p6
Why are elements like neon and argon unreactive?
Because they already have a full outer shell of electrons, which is the most stable configuration.
What group of elements do not have an identical outer electron configuration?
noble gases Helium has 2 valence electrons, whereas the rest have 8.
How do the electron configurations within?
The core of the configuration is the same for all elements in a group, the outer shell electrons are also arranged similarly.
What do elements in each group have in common?
Electron configuration - they have the same number of elements in their outer 'electron shell'. This induces them to have similar bonding properties, and so elements in the same group are chemically similar.
Will Argon tend to form bonds with other elements?
No it will not because it has a filled outer layer/shell so it has a stable outer energy level as shown by its electronic configuration of 2:8:8
An electron configuration that is not chemically reactive?
Where there are 8 electrons in the outer shell so a full shell. Elements are reactive when they need to lose or gain an electron. The noble gases are unreactive as they have a full outer shell.
What the correct electron configuration for chlorine?
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5.
