valancey is something or the spots left to be filled by electrons in a the last shell

ok. nubeer what is the valency of mg

Areesha.1D Group TitleBest ResponseYou've already chosen the best response.0
1) Find out the electronic configuration. That is the number of electrons for that ion. Electronic config. for Mg is 2,8,2. 2) Now see how many electrons you get in the last orbit. 3) That number become your valency. Mg is +2. If the last is more than four then it means it is the negative ion and hence check how many electrons are needed to stabilize that ion. For eg. Chlorine is 2,8,7. Therefore to complete the octet, it needs 1 electron and hence valency of chlorine is 1. You need to see weather the number of electrons in last orbit is more than, less than or equal to 4. If more than it is a negative ion and its valency can be 1,2,3. If less than 4 than valency can be +1,+2,+3. And if equal to 4 than it is a metalloid which acts as a metal as well as a nonmetal. Eg. silicon. Valency of Na is +1 coz its electronic config. is 2,8,1. And now you find out for V as a practice. Valency is the combining capacity of an element and valence electrons are the number of electrons in the last orbit which are lost, gained or shared during the course of a reaction.

@mayankdevnani yeah, i brought you information you needed, yet were incapable of finding yourself.

lol what she is said is right.. ok few things you should know is The valency of an element is the measure of electrons it needs or needs to loose to obtain a stable structure.. what is stable structure.. stable structure is when any atom have 8 electrons in the last shell.

nubeer Group TitleBest ResponseYou've already chosen the best response.3
so if we take Mg.. it has configuration 2,8,2 means it has 2 electrons in the outer most shell.. whether Mg can loose 2 electrons or gain 6 more.. it's easy to loos 2 rather then gaining 6 electrons so Mg preferes to loose.. so when Mg loose it will get a charge of+2 on it.

nubeer Group TitleBest ResponseYou've already chosen the best response.3
group 1 to 3 looses electrons these groups also called metals.. and the nonmetals looses electrons.

ok..so what is the valency of cl
 one year ago

nubeer Group TitleBest ResponseYou've already chosen the best response.3
Cl.. 2,8,7.. tell me what u think its easy for him to loose or gain to achieve it's outer shell to be filled by 8 electrons.?

@nubeer let him figure it out.

looseing right!!

nubeer Group TitleBest ResponseYou've already chosen the best response.3
yes @Areesha.1D i have told him all the details won't tell answer will just walk him through..
 one year ago

nubeer Group TitleBest ResponseYou've already chosen the best response.3
hmmm nooo.. do u think he will just break 7 parts of it structure and not just having 1 more electron.. llook u have to think loosing and gaining is same it's not about tough.. think which is easier way to have 8 electrons in outer shell.. whther he can just gain 1 and have 8 or loose 7 electrons.

@nubeer exactly! have fun llol

mayankdevnani Group TitleBest ResponseYou've already chosen the best response.1
hmmm, he can just gain 1 and have 8 .right
 one year ago

nubeer Group TitleBest ResponseYou've already chosen the best response.3
yes.. so its easy and when any atom gain an electron it get's a positive charge.. so what charge you think Cl will get?
 one year ago

mayankdevnani Group TitleBest ResponseYou've already chosen the best response.1
i don't know!!! plz tell me and give me another example and i can do this..k
 one year ago

nubeer Group TitleBest ResponseYou've already chosen the best response.3
look when electron is loose positive charge appears and when gains a negative charge appears.. so Cl gain 1 electron so it will get 1 charge.. u can take any if by any chance hypothetcially Cl gains 4 electron then it gets 4 charge and if it loose 7 electron so will get +7 charge.. get it? do for Al.

have to make 8 in last shell.. so right now 3 in last shell so easy to loose or gain?
 one year ago

mayankdevnani Group TitleBest ResponseYou've already chosen the best response.1
gain
 one year ago

nubeer Group TitleBest ResponseYou've already chosen the best response.3
hmm how much have to gain to get 8? it would have to take 5 more .. so no.. its better to loose look group 13 will loose electrons.. and group 58 gains electrons.. made more easy for u.
 one year ago

nubeer Group TitleBest ResponseYou've already chosen the best response.3
now look in which group Al is in the periodic table.

but howz that...it loose its electrons
 one year ago

nubeer Group TitleBest ResponseYou've already chosen the best response.3
yes how many it loose? 3 .. and when any atome looses it gets a positive charge..
