This is hard to show but here is how you would determine these. NOTE each dot is an electron.
<span>Question 1) </span>
<span>F-H </span>
<span>1) determine the valance electrons for each. F has 7 and H has 1 </span>
<span>2) one electron from both F and H form the bond "-" which means that you still have 6 electrons to place around F and none to place around H. Place the 6 in sets of 2 around the F </span>
<span>.. </span>
<span>F-H </span>
<span>¨ </span>
<span>Question 2) </span>
<span>2) H-O-H </span>
<span>H has 1 valence electron minus 1 used in the bond to O = 0 electrons to place </span>
<span>H has 1 valence electron minus 1 used in the bond to O = 0 electrons to place </span>
<span>O has 6 valence electrons minus 2 used in the bonds to the H's = 4 electrons to place </span>
<span>H-O-H: place two dots above and below the oxygen </span>
<span>Question 3) </span>
<span>3) O=N----H : NOTE: a double bond requires O and N to share two of their electrons each </span>
<span>O has 6 valence electrons minus 2 used in the bonds to N = 4 electrons to place </span>
<span>N has 5 valence electrons minus 3 used in the bonds to O and H = 2 electrons to place </span>
<span>H has 1 valence electron minus 1 used in the bond to N = 0 electrons to place </span>
<span>place the 2 dots on top and bottom of oxygen. </span>
<span>place 2 above the N </span>
I believe you just subtract the atomic mass and atomic number. (N= M- n)
Hey there!
The first one:
The 20 means it has 20 protons. The 42 means the sum of protons and neutrons is 42, so that means 20 protons plus 22 neutrons is 42 total. There is no charge noted, so the number of electrons is equal to the number of protons.
This atom has 20 protons, 22 neutrons, and 20 electrons.
The second one:
The 20 means it has 20 protons. The 44 means the sum of protons and neutrons is 44, so that means 20 protons plus 24 neutrons is 44 total. There is no charge noted, so the number of electrons is equal to the number of protons.
This atom has 20 protons, 24 neutrons, and 20 electrons.
Hope this helps!
Electron domain geometry takes into account the bonds and the free electrons around the atom to predict the geometry.
A tigonal planar geometry means that all the electron domains are in the plane and that they are as far away as they can. That means that there are three electron domains in the plane separated at 120 ° each other.
sp2 means that there are three hybrid electron domains, and the geometrh that leads to the minimal repulsion force is they placed at 120°, which exactly the trigonal planar geometry described up.
Then the answer is sp2
You can check in your book, that sp corresponds to two domains, located linearly, at 180°; and sp3 is four domains with the form of tetrahedral with 109.5° angles.
answer:
I think nine
explanation:
Nuclear fission : It is defined as the splitting of bigger nuclei into two smaller nuclei. During this process neutrons and some energy also released.
