The 4H is the lightest pencil.
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
The lightest 'non-metal' could be Hydrogen and Helium! Both are gases, and therefore, not a metal.
Protium (Hydrogen-1) is the lightest and by far the most common isotope of hydrogen.
Pencil "lead" is actually made of graphite, which is a form of carbon. The graphite is mixed with clay to give it form and strength. These mixture of graphite and clay are then encased in wood to create a pencil.
The lightest alkaline earth metal is Beryllium(Be) having atomic mass 9.012 dalton. The heaviest element in this family is radium.
The shades of graphite pencil from lightest to darkest are typically categorized as 9H (lightest), 8H, 7H, 6H, 5H, 4H, 3H, 2H, H, F, HB, B, 2B, 3B, 4B, 5B, 6B, 7B, 8B, 9B (darkest). The 'H' pencils are harder and lighter, while the 'B' pencils are softer and darker.
You would use a pencil sharpener to sharpen a pencil.
in the pencil uses lead
in the pencil uses lead
pencil is use in chromography because the pencil is made from lead
we use the pencil, protractor and a compass. we use the pencil, protractor and a compass.
you have to talk to the porter and she will tear the orders out. then you have to use the pencil to rub on the tablet and that's where you use the pencil. Hope this helps! :D
The opposite of lightest is heaviest.
the lightest elements are gases and the lightest of these are hydrogen and helium.
it differs really on how much you use the pencil and how hard you use it.

An unsharpened pencil is often referred to simply as a "pencil." In some contexts, it might be called a "new pencil" or a "blunt pencil," indicating that it has not yet been sharpened for use.
