What causes the reactivity of elements?
What do all atoms want?
A completely full valence shell
What is a full valence shell (normally)?
Noble gases's valence shell
Full (have 8 electrons)
What kind of elements tend to be the most reactive?
Elements that are really close to a full shell (halogens and alkali metals)
Metals ___ electrons to gain a full valence shell
Nonmetals ___ electrons to gain a full valence shell
Metalloids and gaining a full valence shell
Can gain or lose electrons
Quickest way for something with more than 4 electrons to get a full valence shell
Gain electrons through chemical bonds
Halogens want to gain how many electrons?
The Oxygen group wants to gain how many electrons?
The nitrogen group wants to gain how many electrons?
How is it that some elements gain a full valence shell by losing electrons?
There is a full shell underneath (unless it is hydrogen)
Alkali metals want to lose how many electrons?
Alkaline earth metals want to lose how many electrons?
The boron group wants to lose how many electrons?
The carbon group wants to lose how many electrons?
Charged atom or molecule
How does something become an ion?
By gaining or losing
Negatively charged ion
What causes anions?
Positively charged ion
What causes cations?
Alkali metals form ions with a __ charge
Alkaline earth metals form ions with a __ charge
Halogens form ions with a __ charge
The oxygen group forms ions with a __ charge
Elements that gain electrons form what ions?
Elements that lose electrons form what ions?
Ions vs the element of the same name
What is mainly responsible for chemical/physical properties?
Why are alkali metals so reactive?
They "want" to get rid of the 1 electron in their valence shell
Atom reactivity after losing the electron it doesn't want
The atom is nowhere near as reactive as it used to be
Are ions like noble gases?
, they are not
Valence electrons are mainly responsible for chemical/physical properties, but...
They are not solely responsible
What also plays a role in chemical/physical properties?
Protons and neutrons
When K loses an electron or Cl gains an electron...
-They have the same number of electrons as Ar
-But the number of
-So K+, Cl-, and Ar are
, even though they have the
same number of electrons
What do charges also affect?
Properties of an element
Charges on a neutral charge
They are unaffected by a positive or negative charge
Charges on a negative charge
Attracted to a positive charge and repelled by a negative charge
Charges on a positive charge
Attracted to a negative charge and repelled by a positive charge
What will a metal have an ionic bond with?
(Something from the left bonding with something from the right)
A transfer of electrons
-Something gives up electron(s), something takes electron(s)
What holds ionic bonds together?
Electromagnetic force (nothing shared between them, they are opposite charges that attract each other)
Large amounts of ionic bonds that have stacked together
Is there an ionic "molecule"?
-There isn't exactly an ionic "molecule"
-There's just a
ratio of loose ions stacked together
-Is sometimes called a
Ionic bond's strength
Is the weakest bond that is considered a bond
Ionic bonding is only an attraction between particles...
However, the attraction is strong enough to call it a bond
Other attractive forces
There are other attractive forces between particles that are
Different kinds of salts
-Salt does NOT just mean table salt (NaCl)
any of 1000's of ionic crystalline solids
Ionic compounds resulting from an acid-base reaction
