Final answer:
The element in Group 4A (14), Period 2, is Carbon, with the symbol C. Carbon is an essential element in many biological and material sciences due to its tetravalent bonding patterns.
Step-by-step explanation:
The element described by Group 4A (14), Period 2 is Carbon (C). In the Periodic Table of the Elements.
Group 4A (or Group 14 using the IUPAC numbering system) corresponds to the carbon family, and Period 2 refers to the second horizontal row.
Carbon is well known for being the fundamental building block of all known life, and its versatile bonding patterns make it incredibly important both in biology and material sciences.
Within its group, carbon is the first element and has the feature of typically forming tetravalent bonds, thereby exhibiting a valency of four.
