Resume of Fakhruddin Ar-razi
a. Definition Atom
Atom defined as particle The smallest from something Theory that no could be dividedfor again, will but from result invention next evidently atom still consist on particles that more
small again that called particle subatomic. Particle The sub-atomic is:
1. Proton
2. Neutron
3. Electron.
From the findings, it turns atom consists of particles Its simple, the so-called sub-atomic
particles. Subatomic particles are: protons, electrons,and neutrons. Electrons are atomic particles
were first discovered, the electrons found By Joseph John Thomsona British scientist.Proton
constitute particle charged positive, position located in the nuclei. The existence of protons in the
atomic nucleus was not alone.
b. Struktur Of Atom
With the discovery of the structure of atoms, then the difference between the atoms one by
others can be explained. The difference is caused by differences in composition, ie the number of
protons, electrons, and neutrons. In connection with the arrangement of atoms, we need to
understand some terms, namely:
1. Atomic Number
2. Number Mass
3. Natation Atomic Strukture
A question from fahrian bachri to fahruddin arrazi is how to calculated the number of electron
and neutron of O2I as a participant only answered greetings and helped Razi in reading one ofe the slides.
Resume of Mar’Atus Sholeha
Alcene is a hydrocarbon coumponds that have a double bond (C=C) and are usually also
called an unsaturated coumpound. As For the Structure of the alkenes is brounched structure
alkenes, and unbranch alkene structure
Characteristic of unsaturated hydrocarbon coumbonds:
a. Alkene Contains a double bond between the carbon atoms
b. Very reactives, and
c. having Addiction reaction
Liquid bromine test can distinguish saturated or unsaturated hydrocarbonds: Alkenes,
don’t react with liquid bromine, alkene and alkyne react with liquid bromine is characteristic by
the appearance.
A question from Fahrian Bachri is what is the differences between alkane, alkene, and akune?
Mar’Atus Sholeha answer :
Alkane is a saturated hydrocarbon which means they are coumpounds with a single bond
between, alkenses are unsaturated hydrocarbonds which means they are coumpounds with one or
more double bonds between carbon atoms, while alkuna is also unsaturated hydrocarbonds, they
have one or more threefold bonds between carbon atoms
