<span>One atom of silicon can properly be combined in a compound with two atoms of oxygen.</span>
Explanation:
Element Abundance percent by weight Abundance parts per million by weight
Oxygen 46.1% 461,000
Silicon 28.2% 282,000
Aluminum 8.23% 82,300
Iron 5.63% 56,300
<span>Answer:
Iron triad are used in the process to create steel and other metal mixtures.
Coinage Metals are used for much more than just coins, and many other elements besides these are made into coins.</span>
It was due to the metal foil in which the alpha particles can't even pass through. This experiment conducted by Rutherford led to the discovery of protons.
Answer:
Explanation:
As can be seen in the Figure in a face-centered cubic unit cell you have:
- Six halves of atoms
- Eight 1/8 of atom (1 in each corner)
In total:
Now, each side of the cell is 234 picometers (2.34e-8 cm) long
Atoms per cm3:
Expressing in mass:
