SCI6
How many electrons are shared in a double covalent bond
Four
T/F
In a covalent compounds , atoms become chemically stable by sharing their valance electron
True.
T/F
Noble gases are generally non-reactive because they already have complete valence shell
True
T/F
Electrons in a covalent bond are always shared equally between the two atoms forming the bond.
False.
T/F
All compounds with polar covalent bondss re polar molecules
False
T/F
An oxygen atom , having electron configuration1S2 2s2 2p4 , forms a single bond with another oxygen atom
False.
T/F
Carbon May form a triple bond and a single bond in the same molecule
True.
Explain how soap works
On soap the head is polar, while the tail is Nonpolar, when washing your hands the polar part attracts water which is polar and the Nonpolar tail attracts the dirt which is Nonpolar. Than are three together dirt/water/ soap goes down the drain.
Compare and contrast ionic and covalent
Ionic : whats to look like a noble gas Metals to nonmetal Transfer electrons (Na+ + Cl- = NaCl) Forms ions Stronger Covalent : whats to look like a noble gas Non metals to nonmetals Shares Cl + Cl = Cl - Cl
