Answer:
C
Explanation:
As the temperature increases, the kinetic energy of the molecules increases.
Answer:
Although atoms are the smallest units that can be found in all matter, these atoms have a complex structure when experimentally analyzed. In order to understand almost all concepts in chemistry, it is essential to clearly understand the basic structure of an atom. Crystals are solid compounds made out of a number of atoms or molecules. There are particular arrangements in crystals. These arrangements are called crystal structures. Examining the crystal structure is very important in determine
Explanation:
B,Si,Ge,As,Sb,Te, and At are all the metalloids on the periodic table of elements.
From the periodic chart the only element between F and Na is Neon. Neon has one more valence electron 8 than fluorine 7, and is one energy level shy of Na.<span>
