Answer from: oroman4650

There are 4 bonding electrons (2 pairs) and 16 non bonding electrons

Explanation:

Working this out if quite easy first:

Calculate the total number of valence electrons.

F=7 (Since it's in row 17)

F=7

O=6

Total number of electrons equals 20

Then calculate the number of electrons if all the elements had full valence shells

F=8

O=8

Total number of electrons equals 24

Then minus the total number of full shells by the non full shells

24-20= 4

Divide this number by 2 (Since bonds consist of 2 electrons)

The total number of bonds is 2

we can then draw this by placing the O in the middle since there are 2 Florine molecules. Then we complete the Octet rule. (each element must have a total of 8 electrons around it including the bonding electrons. If you have done it correctly then the number of non bonding and bonding electrons should equal the total number of electrons in this case 20)

In the image I drew the bonding electrons as red and the non bonding electrons as black. Sometimes the bonding electrons are drawn as lines this is the same as drawing dots.

Answer from: Quest

Mass is the amount of matter in an object. weight is the measurement of the pull of gravity on an object. say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165) now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon. however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant. in conclusion it is possible for your weight to change as your mass remains constant.
