Answer:
I'm just guessing/deducting here, but:
1. Because the electronegativity of silicon is much stronger causing electrons to be much less conducive.
2. Extra free electrons = is more charged particals that can move freely and thus conduct electricity. So the resistivity will be lowered.
Explanation:
Answer :C) through transferring or sharing electrons
PH = -lg[H+]
pH = -lg[6.38·10-6] = 5.2
Answer:
Here's what I get.
Explanation:
(a) F, Cl, Br, and I are called halogens (salt formers)
(i) They are placed in Group 17, the Group just before Group 18 (the noble gases), because they need just one more valence electron to get a noble gas electron configuration.
(ii) At room temperature, iodine is a lustrous, purple-black solid that melts to form a deep violet liquid at 114 °C.
