The Periodic Table Flashcards
1
Q
Properties of metals and non-metals
A
Metals:
- Conduct electricity
- Metal oxides are basic
Non-metals:
- Poor conductors of electricity
- Non-metal oxides are acidic
2
Q
How is electronic configuration related to position on the periodic table?
A
The number of shells is the same as the period. The group number tells you how many electrons there are in the outer shell.
3
Q
Why do elements in the same group have similar properties?
A
They have the same number of outer shell electrons
4
Q
Why do noble gases not react?
A
They are inert because they have a full outer shell of electrons and it takes a lot of energy to add or remove electrons from a noble gas shell
