Atoms, Compounds and Isotopes
- Contains 3 smaller types of particle
- Protons
- Neutrons
- Electons
- Atomic number and Mass number
- Atomic Number
- Number of protons
- Atoms from the same
element have the same
number of protons
- The Mass Number
- Total number of protons and neutrons
- To get the number of neutrons
just subtract the atomic number
from the mass number.
- Compounds are chemically bonded
- Compounds are formed when
atoms of two or more elements are
chemically combined together
- E.g. Carbon dioxide is a compound
formed by a chemical reaction between
carbon and oxygen
- /its difficult to separate the 2 original elements out again
- Isotopes are the same except for an extra Neutron or Two
- Isotopes are different atomic forms of the same element which have the SAME number of PROTONS but a DIFFERENT number of NEUTRONS
- Carbon 12 and Carbon 14 are examples
- Isotopes must have the
same atomic forms of the
same element atomic
number but different mass
numbers
- If they had different atomic
numbers they would be be different
elements altogether
