Elements in Group 14

Carbon

Silicon

Germanium

Tin

Lead

Carbon

a) Name of element= Carbon

b) Symbol of element= C

c) Atomic Number of element= 6

d) Atomic Mass of element= 12

f) How many valence electrons does this element have? =4

g) What are the uses for this element?= Carbon is also the basis of fuels such as coal and oil since both coal and oil are rich in carbon. Carbonas graphite is a good lubricant. Carbon is a key component of steel.

h) Who discovered this element? =it was known since ancient times.

Silicon

a) Name of element= silicon

b) Symbol of element= Si

c) Atomic Number of element= 14

d) Atomic Mass of element =28

f) How many valence electrons does this element have? =4

g) What are the uses for this element?= Hyperpure silicon can be doped with boron, gallium, phosphorus, or arsenic to produce silicon for use in transistors, solar cells, rectifiers, and other solid-state devices which are used extensively in the electronics and space-age industries.

h) Who discovered this element?= Jöns Jacob Berzelius

Germanium

a) Name of element= Germanium

b) Symbol of element= Ge

c) Atomic Number of element =32

d) Atomic Mass of element =72.6

f) How many valence electrons does this element have?= 4

g) What are the uses for this element?=The largest use of germanium is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices.

h) Who discovered this element?=Clemens Winkler

Tin

a) Name of element-Tin

b) Symbol of element Sn

c) Atomic Number of element- 50

d) Atomic Mass of element-118.710

f) How many valence electrons does this element have? 4

g) What are the uses for this element? Tin has many uses. It takes a high polish and is used to coat other metals to prevent corrosion, such as in tin cans, which are made of tin-coated steel. Alloys of tin are important, such as soft solder, pewter, bronze and phosphor bronze. A niobium-tin alloy is used for superconducting magnets.

h) Who discovered this element? Ancient times/ Romans

Lead

a) Name of element-Lead

b) Symbol of element-Pb

c) Atomic Number of element- 82

d) Atomic Mass of element-207

f) How many valence electrons does this element have?4

g)what are the uses for this element? The single most important commercial use of lead is in the manufacture of lead-acid storage batteries (see battery, electric). It is also used in alloys such as fusible metals, antifriction metals, solder, and type metal. Shot lead is an alloy of lead, antimony, and arsenic

h)Who discovered this element? Ancient times/ Romans
