Question

why does the reactivity of metals increase down the perioodic table ?

Answer 1

@Abmon98 @SchoolKid @taylor12344 @trueseminole @wio

Answer 2

I think you are thinking of Group 1 and 2 metals. They get more reactive as you go down the column (group), as the electropositivity increases and they are more willing to just take of their extra electrons.

Answer 3

group 1 and 2 like giving electrons
not taking

Answer 4

and that is not the reason

Answer 5

I apologise for causing any confusion...Somy came up with a far superior answer

Answer 6

reason is that as you go down the group number of shells increases thus effect of nuclear charge on electrons (meaning attraction or pull of electrons by protons (opposite charges) ) decreases as they are more away from the nucleus
valance electrons are pretty much away from nucleus thus they can be lost easily

Answer 7

thank u @Somy

Answer 8

u are welcome :)

Answer 9

@SchoolKid btw electronegativity decreases down the group :)

Answer 10

@Somy oops. looks like I need to review my stuff on the Periodic table! Thank you

Answer 11

you are welcome :))) its easy to remember if you know about Florine
Florine is THE MOST electronegative element in periodic table

Answer 12

so if you look at periodic table you can guess by looking at the period, since Florine is at the end of the period and You knot its the most electronegative, that must mean electronegativity increases as you go across the period
now when you look at groups, and again you know that Florine is most electronegative - so that must mean anything below Florine should be less electronegative so that means electronegativity decreases down the group

Answer 13

know*

Answer 14

Yes, it does make more sense now! Thank you. Couldn't have asked for better help

Answer 15

you are welcome :))) @SchoolKid

Answer 16

somy is too smart

Answer 17

^^Cant disagree with that

Answer 18

lol @hari5719 im not lmao i just had to deal with electronegativity a lot so it stayed in my brain lol

Answer 19

ok i think i have another question

Answer 20

reason why reactivity of non metals decrease down the group

Answer 21

@Somy

Answer 22

lol

Answer 23

wat the heck is lol for @chmvijay sry if i am rude

Answer 24

for non metals its what @SchoolKid said but the opposite way round
non metals prefer to Take electron rather then Give

Answer 25

man ure awsome somy

Answer 26

lol thnx

Answer 27

can i get an clear answer for the second one i dont understand

Answer 28

concept is same for both Metals and non metals btw
in case of metals they like Giving
while non metals like Taking
now look
as i said
as we go down the group there are More shells
thus pull of proton in the nucleus is weaker as there are more shells
thats why we can loose electron easily in metals

in case of non metals
because attraction is sooo week between nucleus and valance electrons its hard to pull the other electron from something else to itself
that is why as we go down the group in case of non metals
electronegativity decreases

Answer 29

i hope its clear :D

Answer 30

very clear thank u

Answer 31

you are welcome :DD
