1
Formation of light elements, Hydrogen and Helium by combining the protons and neutrons right after the Big Bang
BIG BANG NUCLEOSYNTHESIS -
2
Responsible for the formation of elements heavier than Helium (He) until Iron (Fe).
STELLAR NUCLEOSYNTHESIS –
3
Believed to be the reason for the formation of heavier nuclei after iron (Fe).
SUPERNOVA NUCLEOSYNTHESIS -
4
- a device used to accelerate (speeds-up) particles to produce heavier nuclei upon hitting target nuclei. An example of this is the cyclotron. This device led to the creation of elements in the laboratory (technetium and promethium, were produced using a cyclotron).

HYDROGEN BOND
10
- Between a polar covalent compound and another polar covalent substance.
DIPOLE – DIPOLE
11
- Between a polar and non-polar molecule.
DIPOLE – INDUCED DIPOLE
12
- A temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
