Question

How many valence electrons are shared, gained, or lost by each atom of the six compounds?
• N2 • CCl4 • SiO2
• AlCl3 • CaCl2 • LiBr

Answer 1

I bet you can do LiBr without our help and you can probably do the others as well. You know that Li will be +1 (loses electron) and Br will be -1(gains electron)
Google valences of each or look in your book

Answer 2

so does that mean that Li will lose 1 electron and Br will gain 1 electron

Answer 3

Yes, that leaves them both with full shells. This has to be in your book!
or google ionic bond and covalent bond

Answer 6

so Cl gain 7 electrons right

Answer 7

would N2 have to gain 3 electrons to have a full shell?

Answer 8

oh wait will Cl gain 1 electron to have a full shell?

Answer 9

Of course Cl will gain 1 e to have a full shell which give it a -1 charge.However, if combined with C it will share electrons with Cl to form four covalent bonds. SiO2 is covalent as is N2.

Answer 10

none of this makes any sense to me ;-;

Answer 11

same Lyssa

Answer 12

how does this apply to my everyday life day life
