C3: Structure And Bonding Flashcards
What is a mettalic bond?
A bond made up of only metal elements
What is a covalent bond?
A bond made up of only non-metal elements
What is an ionic bond?
A bond made up of metal and non-metal atoms
What can group 1 and group 7 elements react together easily?
Because group 1 elements want to loose 1 electron to become noble, and group 7 elements want to gain 1 electron to become noble. So the group 7 element can take the group 1 elements electron so they can both become noble.
What are the 3 states of matter?
Solid, liquid and gas
Do opposite charges repel or attract?
Attract
Do small molecules have high or low melting and boiling points?
Low
What are some physical propertys of a metal?
Solid
Atoms in a fixed position
Cannot change shape
What is nanoscience?
The study of structures between 1 and 100 nanometers (nm) in size
What is a nanoparticle?
A tiny particle that is 1-100nm in size
What are some uses of nanoparticles?
- Transparent sun creams
- Anti-grafitti coating for walls
- Scratchproof glasses
