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
How many valence electrons are shared, gained, or lost by each atom of the six compounds?
• N2 • CCl4 • SiO2
• AlCl3 • CaCl2 • LiBr
12 answers
so does that mean that Li will lose 1 electron and Br will gain 1 electron
Yes, that leaves them both with full shells. This has to be in your book!
or google ionic bond and covalent bond

so Cl gain 7 electrons right
would N2 have to gain 3 electrons to have a full shell?
oh wait will Cl gain 1 electron to have a full shell?
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.
none of this makes any sense to me ;-;
same Lyssa
how does this apply to my everyday life day life
