P1 - 1.10 Metals And Non Metals (And Alloys, Reactions Of Metals) Flashcards
Atomic Structure & The Periodic Table
Where can you find metals on the periodic table
Bottom left
The periodic table mainly consists of which:
Alloys
Gases
Metals
Metals
Do metals form positive or negative ions when they react
Positive
How would you write a calcium ion with a +2
[Ca]^+2
What kind of ions do non metals form
- they dont form ions
Or - they form negative ions
How would we write the negative ion chlorine -1
[Cl]^-
How does the electron arrangement determine whether an ion is formed
If the atom has a full outer shell of electrons in order to be stable
If Ca is in group 2 how many electrons will it have in its outmost shell
2 because it is in group 2
How do we quickly work out how many electrons shells are in an atoms outmost ring
Look at the group number on the periodic table
On the left hand side of the periodic table is it easier for the atoms to gain or lose electrons
Lose electrons which there turns it to be a positive ion
On the right hand side of the periodic table is it easier for the atoms to gain or lose electrons
It is easier to gain electrons making it a negative ion
In a chlorine atom how many electrons are gained or lost
One electron is gained
[Cl]^-
When gaining or losing electrons does it take a lot of energy
It uses up a lot of energy which is why we dont just lose 7 electrons for example in a group 7 atom
Is the top or bottom of the periodic table more reactive
Bottom as they have a lot more shells
Why are the atoms at the bottom of the periodic table more reactive
They have a lot more shells so the outmost shell is the furthest away from the nucleus therefore cant hold onto these rings as strongly so lose electrons easier
Which subatomic particle holds the electron rings in place
Nucleus
In an atom with fewer electron rings is it less or more reactive
Less reactive because the nucleus can easily hold onto the rings
In an atom with more electron rings is it less or more reactive
More reactive because the nucleus cannot easily hold onto the rings
At group 4 is it easier to gain or lose electrons
Losing electrons takes less energy therefore it loses 4 electrons
