Bonding Flashcards
What does metallic bonding consist of?
Metal ions surrounded by delocalised electrons
What is metallic bonding?
The attraction between the charged metal ions and the electrons
Melting points of metals?
High, due to the high amount of energy required to overcome the strong metallic bonds
Why so metals conduct electricity?
The electrons are free to move
Hydrogen, nitrogen and oxygen are examples of what?
Diatomic molecules consisting of two atoms joined by covelant bonding
3 types of bonding in elements?
Metallic, covelant, LDS
Why are metals malleable and ductile
The metallic bond is not fixed so the atoms can slip past each other
Metals melting and boiling points?
High
What are monotonic gases?
Noble gases, that have full outer electron shells
How are temporary dipoles formed?
When electrons end up on one side of the atom due to election cloud wobble meaning one side is more negative than the other
What is a dipole dipole attraction
When a dipole induces other atoms to form dipoles
Why do bps of Noble gases increase with the size of the atom
London forces are increasing with the number of electrons. The more electrons, the bigger the dipole, the stronger the London forces
Covelant bond?
Formed when a pair of electrons are shared, mutual attraction of two opposite nuclei for a shared pair of electrons
What do most non metals exist as?
Discrete covelant molecules
Larger molecules have_____ lds forces between them because_____
Stronger, more electrons
