- Chemistry-C1
- Atoms
- The nucleus
- Middle of atom
- Contains protons and neutrons
- radius of around 1*10/\-14\/m
- Positive charge because of the protons
- Almost the whole mass
- Atomic number
- Tells you how many protons there are
- Mass number
- Tells you total number of protons and neutrons
- Number of protons = number of electrons
- The nucleus
- Elements
- Consists of atoms with the same atomic number
- Isotopes
- Isotopes are different forms of the same element, which have the same number of protons but a different number of neutrons
- So isotopes have the same number of protons but a different number of neutons
- RAM=sum of(IA*IMN)/ sum of (AofAI)
- RAM=Relative atomic mass
- IA=Isotope abundance
- IMN=Isotope mass number
- AofAI= Abundance of all the isotopes
- Isotopes are different forms of the same element, which have the same number of protons but a different number of neutrons
- Atoms
