Chapter 3: Bonding Flashcards
Three types of strong chemical bonds.
Ionic, Covalent and Metallic.
What is a covalent bond?
A shared pair of electrons between two non-metals.
What is a noble gas?
An element which has a full outer shell, found in group 8/0.
What are electrostatic forces?
The forces of attraction and repulsion between electrically charged particals.
What bond always makes a structure called a latice?
It’s ionic.
True or false:
Non-metal atoms need to recieve electrons to fill the spaces in their outer shell?
True!
Properties of ionically bonded compounds, give examples:
Always solids at room temprature
Giant structures
high melting temp
Conducts electricity when molton but not when solid
What does dipolar bonds mean?
They are bonds which have to poles which are forces.
Can diamond have intermolecular forces?
No because for intermolecular forces to be present there needs to be multiple molecules, diamond is made up of multiple crabon atoms tehrefore is the molecule.
What is metalic bonding?
A lattice of ions existing in a sea of delocalised electrons.
What are three types of intermolecular forces?
- Van der Waals forces
- Dipole-dipole forces
- Hydrogen bonding
