Bonding (whole Book) Flashcards
Most atoms do not have full electron shells: the exception being…..
Noble gases
What does having a full outer shell do to an atom
Gives the Atom a stable , unreactive property
What’s an ion
An ion is a charged particle formed when an atom gains or losses electrons
What’s a cation
A positive ion
What’s an anion
A negative ion
Left side of the elements
Loos electrons
Right side of elements
Gain electrons for a full outer shell
What’s an molecular ion
Is a charged particle containing two or more atoms covalently bonded
Ionic bond
An attraction between oppositely charged ions
Happens between a metal and a non metal
What is the sentence u need to right below ionic bonding diagrams
Opposite charged ions attract to form a strong ionic bond and form ….
This is diagram with brackets and squiggly line to show bond u need either a + or - next to brackets
Covalent bond
Is a shared pair of electrons
Use Bob diagrams to show that
Between two non. Metals
Molecule
Containing two or more atoms covalently bonded
Diatomic
Means that there are two atoms covalently bonded in the molecule
Ina covalent bond letters diagram what does the - represent
1 single covalent bond
What is electrons out of the covalent bond called
Lone pair
Metallic bonding
Is the attraction between delocalised electrons and the positive ions in a regular lattice
Ductile
Can be drawn into wires
What sentence u you write next to metalic bond diagram
Positive metal ions inna sea of delocalised electrons
Ionic bonds are
Stront and need substantial energy to break ionic bonds
