Question

umm.. again a question to thomaster
i can't find the Atomic radius of Berkelium..

Answer 1

:P

Answer 2

yah.. pls explain this weird variation..

Answer 3

188, 180, 161, 138, 130, 151, 173, 299, 170, 295, 186, 290, 287, 285, 282

Answer 4

this is the sequence for the entire Actinide atomic radius.. the 200+ pm is worrying me.. it's erratic.

Answer 5

only 170 is given by u, the rest is from chemistry.about

Answer 6

I have no idea.. I guess there are some outliers

Answer 7

eh.. that's just wrong.. or printing mistake.. an outliner with a jump of 100+ ?? (Americium 173 -> curium 299)

Answer 8

If any of this info comes out to be false, i'm XP for chem's project..

Answer 9

Another source says that the atomic radius of curium = 174

Answer 10

lol..

Answer 11

http://www.chemicool.com/elements/curium.html

Answer 12

Don't know why chemistry.about says 299 0.o

Answer 13

I'll check all the actinides. give me a sec

Answer 14

okay, then i need the other source atomic radius for Californium, Fermium, Mendelevium, Nobelium and Lawrencium.

Answer 15

lol..

Answer 16

actinium = 195 pm
thorium = 179 pm
protactinium = 163 pm
uranium = 175 pm
neptunium = 175 pm
plutonium = 175 pm
americium = 173 pm
curium = 174 pm
berkelium = 170 pm
californium = 186 pm
einsteinium = 186 pm
fermium = ??
mendelevium = ??
nobelium = ??
lawrencium = ??

Does that make more sense?

Answer 17

That's from http://www.chemicool.com/
But i cannot guarantee that it's correct

Answer 18

ah, i just don't seem to find Fermium, Mendelevium, Lawrencium and Nobelium

Answer 19

maybe they're unknown

Answer 20

Maybe @chmvijay knows

Answer 21

ookay..

Answer 22

Atomic radius 170 pm

Answer 23

see the left measurements of this link
http://www.chemicool.com/elements/berkelium.html

Answer 24

chmvijay?? have u any records of the estimated atomic radius of these 4 elements?
Fermium, Mendelevium, Nobelium and Lawrencium..

Answer 25

u find that to in that above link all elements are there on the right side of that link just check

Answer 26

the atomic radius of Fermium, Mendelevium, Nobelium and Lawrencium are unknown on that site

Answer 27

yah, i checked that.. some ionic radii are mentioned.. but i require Atomic radii..

Answer 28

LOL sory i will get them soon
i am going for dinner hungry ..........
give u later or just Google u will definitely get it :)
@thomaster canu have look at this and give him all the atomic radius including his too :P

Answer 29

i already did :P but i can't find the radius of the last 4 actinides

Answer 30

lol, yeah.. same here..

Answer 31

sorry guys u haven't found them yet

Answer 32

nah..
