1. Lead as in leading the pack or the most??
OR
2. Lead the toxic metal on the element table as Pbatomic weight 82?
Answer for 1. CARBON is the most abundant and leading the pack in elements. Without carbon this would be a dead planet...
Answer for 2. Lead recently was used primarily in Solder: however MERCURY the only liquid metal know has Lead like qualities.... and Mercury would be my best guess...
Please feel free to make comments on my answers; I would love to hear them..
It can't. the properties of an element determine it's group placement, without knowledge of these properties (or, indeed, the element itself) it would be impossible to place an element in it's proper place on the periodic table.
You look at trends. An element is likely to have properties somewhere between the element above it and the element below it; if there's nothing below it (or above it), then you can follow the general trend up (or down) that column and extrapolate.
It is based on the number of protons in one atom.
Least to highest
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
Atomic number most effects the placement of an element in the periodic table.The properties of the element. (Study Island) :p

There are more metals than any other type of element in the periodic table.
It is based on the number of protons in one atom.
yes
The periodic table is based on an element's number of atoms. The elements are arranged from least to most number of atoms.
Calcium
Very common - sodium is found in table salt, for instance.
