Answer:
divide the # of molecules by avogadros number and get 3.48 x 10^-6
Explanation:
Ionic bonds \
The result is a bond where the electron pair is displaced toward the more electronegative atom.
Earthquakes along the San Andreas fault in California.
<u>Explanation</u>:
- When the two plates collide with each other, earthquakes occur. The contact between them makes this earthquake possible. The contact forces are responsible for the earthquakes as there is contact between two plates.
- The gravitational force is a force that is responsible for elevated tides happening on the east coast or the Jupiter's moons to remain in orbit. But this is not a contact force as there is no contact between them
- Moreover, Without any contact, the magnetic force is a non-contact as it attracts the pins from a distance.
System is said to have achieved noble-gas configuration, when it's valance shell is completely filled.
Atomic number of carbon is 6. Thus, it has 6 electrons.
The electronic configuration of carbon is 1s2 2s2 2p2
Now, the inert gas closest to C is Ne, whose atomic number is 10.
Thus, there are excess of 4 electrons in Ne as compared to C.
Hence, carbon must gain 4 electrons to achieve noble-gas configuration.
Alternatively, C can also lose 4 electron to achieve noble gas configuration of He.
Isotopes have different amount of neutrons.
So you can tell what is an isotope by it neutrons.
