- Chemistry Chapter 3 - Part 1
- Atoms into ions
- Losing an electron forms an positively charged ion
- Gaining an electron forms a negatively charged ion
- Metals loose electron
- Non-metals gain electrons
- Ion - A charged particle produced by the loss or gain of an electron
- Ionic bonding
- Ionic compounds are held together by strong forces of attraction between their oppositely charged ions
- Non-metals and metals
- Gain or loose electrons
- Forms compounds!!!
- + or - charged ions but compound charge is 0
- Covalent bonding
- Non-metal and non-metal
- Forms molecules!!!
- Shares pairs of electrons
- Double covalent bond - when two pairs are shared (one of each)
- Macromolecule
- Huge numbers of atoms are held together by covalent bonds eg. diamond
- Non-metal and non-metal
- Nanoscience
- Possible risks
- Accidental sparks can cause explosion
- Breathing in tiny particles could damage lungs and enter bloostream
- The science of tiny particles or structures
- They have a huge surface area to volume ratio
- Possible risks
- Atoms into ions
