yes
the alkaline earth metals
Yes it is from my knowledge but I am not sure so look it up on Google
Because calcium is a soft metallic element, and a hammer (presumably made of iron) is harder and more dense than the calcium.
Depending on the minerals in their composition, some rocks are harder than others. Rocks that contain minerals with higher ratings on the Mohs scale are harder, and would erode more slowly than other rocks.
The bigger the grain, the harder it is for wind to move it.
it is where pressure increases and gets harder to travel through
nanodiamonds
the harder one
The lazy element is when you lay on your back slash side and take your left and right hand and start to move it slowing then gain speed as you get harder and harder
No. No substance known to exist is harder than diamond and especially no other element.
it is silver
neither its tungsten, a diamond is harder but it is not an element since it is not in the periodic table.
Typically copper, but it is much harder than copper.
You use the choke tube which is appropriate to the use of the shotgun. Choke tubes are short sections of tube which screws into the muzzle end of the shotgun barrel. Different tubes hve different amounts of constriction (full, modified, improved, cylinder bore, etc). The tighter the constriction, the more the shot column is kept together and thus the more dense the shot column. This keeps the column together longer as it flies down range and thus will put more pellets into the target. Tighter shot column also means that the pattern doesn't spread out as much and thus it's harder to hit a given target.
~High Boiling point ~2nd column of Periodic Table ~ has awesome name
you need silvery bars and harder cars get titanium
