Lead on the Periodic Table

From the picture above, you can see that lead is main metal, located in Group 4.  It's placement in group 4 tells us that it has four electrons in its outermost (valence) shell.  Also, lead has an atomic number of 82 which places it in it's numerical order of the number of protons in each element. 

Atomic Radius (PM): 175
I have never seen the unit PM before, so after doing a little research, I discovered that PM is picometers, and 1 PM is equal to one trillionth of a meter (1/1,000,000,000,000)


Atomic Volume: 18.3


First Ionizing Energy (kJ/mol): 715.2


Electron Configuration: 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²4f¹⁴5d¹⁰6p²   
or   [Xe] 6p²4f¹⁴5d¹⁰6p²

Density at 293 K: 11.34 g/cm³

I thought that 293 was such a random number and wondered why researchers would use it.  So, I looked it up and discovered that 273.15 is the freezing point of water on the Kelvin scale.  Then, the formula K = C+273.15.  And if the temperature in Kelvins is 273.15, the temperature in Celsius is 19.85, thus giving us 293 K :)


Atomic Structure:

Electronegativity: 1.8


Melting Point: 327.5° C
Boiling Point: 1740.0° C
The melting point and boiling point are significant to this element because they help determine whether or not it is a metal. Lead is a poor metal, and the poor metals tend to have low melting and boiling points.  Although a high boiling point distinguishes lead from the metalloids.  Also, the poor metals are softer than those of the transition metals.  When burned, toxic fumes are extracted from lead.
