Lead
Atomic number 82
Pb: plumbum
Family: Metal
Chemical Characteristic:  Lead is a soft, malleable poor metal. It is also counted as one of the heavy metals. Metallic lead has a bluish-whitecolor after being freshly cut, but it soon tarnishes to a dull grayish color when exposed to air. Lead has a shiny chrome-silver luster when it is melted into a liquid.
Biomed uses and importance:-Construction and military weapons in the ancient times.
Discovered in the nature or lab created?
-Nature
Who discovered it?
-The Romans found it in Çatalhöyük Turkey.
Industry in which it began:-Industry of construction in the Roman Economy.
Located in human body and where?
-Is a neurotoxin found in bones and soft tissues.
Can we find it in the atmosphere?
-No we cannot

Ununquadium orFlevorium
Atomic number 114
Family: Metal-stable isomer
Chemical Characteristic: Flerovium is projected to be the second member of the 7p series of chemical elements and the heaviest member ofgroup 14 (IVA) in the Periodic Table, below lead. Each of the members of this group show the group oxidation state of +IV and the latter members have an increasing +II chemistry due to the onset ofthe inert pair effect. Tin represents the point at which the stability of the +II and +IV states are similar. Lead, the heaviest member, portrays a switch from the +IV state to the +II state. Fleroviumshould therefore follow this trend and a possess an oxidizing +IV state and a stable +II state.
Biomed uses and importance:
-Recently discovered, as a metal-stable isomer it is nuclear and verydangerous.
Discovered in the nature or lab created?
-Created by which in May 2009, the Joint Working Party (JWP) of IUPAC published a report on the discovery of copernicium in which they acknowledged thediscovery of the isotope 283Cn.This therefore implies the de facto discovery of flerovium, from the acknowledgment of the data for the synthesis of 287Fl and 291Lv (see below), relating to 283Cn.
