Carbon
By: Devin Desir
Who discovered carbon?
• The answer to this question would be no
one really knew who discovered carbon,
but in the late 18th century Antoine
Lavoisier discovered that diamonds were
made from carbon, and René Antoine
Ferchault de Réaumur discovered how to
make steel using a mixture of Iron and
carbon.
When was it discovered?
• Carbon was discovered in 3750 BC.
Atomic Symbol
Atomic Number
Atomic Mass
• 12.0107 ± 0.0008 Amu
Number of protons, neutrons, and
electrons.
• Protons: 6
• Electrons: 6
• Neutrons: 6
Is carbon a metal, metalloid, or
nonmetal?
• Carbon is a non-metal, all elements on the
right side of the periodic table are nonmetals.
Is carbon a solid, liquid, or gas at
room temperature?
• At room temperature (25 C), carbon is a
solid. Carbon has the highest melting
point of all the elements.
Melting Point: 3823 K (3550°C or
6422°F).
Boiling Point: 4098 K (3825°C or 6917°F).
What Group is carbon in?
• The carbon family is element group 14 of
the periodic table because it was founded
way before any other element.
What period is carbon in?
• Period 2
What types of isotopes does carbon
have?
• Carbon has three naturally occuring
isotopes: C-12 (98.89%), C-13 (1.11%),
and C-14 (about 1 part per trillion).
C-14 is not stable, and decays by emitting
an electron (beta minus decay) into N-14,
with a half-life of 5730 years.
There have been fifteen total isotopes of
carbon observed, with mass numbers
ranging from 8 to 22 inclusive.
What is carbon’s electron
configuration?
• The electron configuration of carbon is
1s2 2s2 2p2. The shorthand version is [He]
2s2 2p2.
•
Ionization
• the condition of being dissociated into ions
(as by heat or radiation or chemical
reaction or electrical discharge)
• The ionization energy of carbon is CN+ ->
C(N+1)+ + e-
What ion is carbon
• The charge of C ion should be 4-. Only
metals and hydrogen in an acid form
positive ions.
•
Atomic radius of carbon
• Atomic radius of carbon is70 pm.
Electro negativity
• The electro negativity of carbon is 2.55.
• Define Electro Negativity: the tendency of
an atom or radical to attract electrons in
the formation of an ionic bond.
3 Interesting facts
• Pure carbon exists free in nature and has
been known since prehistoric time.
• Carbon is the fourth most abundant
element in the universe.
• Carbon has the highest
melting/sublimation point of the elements.
