Question

which of the following elements is most electronegative?

A) Ununoctium (Uuo)
B) Francium (Fr)
C) Hydrogen (H)
D) Helium (He)

Answer 1

well first look for the number of electrons and protons

Answer 2

i know the answer just wanna make sure im right

Answer 3

electrons are negative and neutrons are positive
if you have more electrons than neutrons it will be negative

Answer 4

which one is it tho

Answer 5

youll have to figure it out i gave you the material now its up to you to solve it

Answer 6

its D lmao all i said was i wanted to make sure i was right

Answer 7

Well, Ununoctium is unknown for its electronegative.

Answer 8

every question im posting i have the answer right in front of me just gotta make sure im not second guessing myself

Answer 9

And Hydrogen is bad at electronegative.

Answer 10

lol i know i got in trouble for answering directly so

Answer 11

I'd say your correct.

Answer 12

wait... there isnt chlorine

Answer 13

no

Answer 14

the info he/she put in is useless then lmao

Answer 15

who that one dude

Answer 16

"corey777"

Answer 17

exactly im happy im not the only one who caught that

Answer 18

jeez corey good job tho

Answer 19

but good job corey

Answer 20

lol sorry wrong answer for this

Answer 21

its okay

Answer 22

I'm going to do some LaTex practicing.

It's not Helium because noble gases have their valencies full, so they are typically unable to form a compound. Noble gases other than Xe and Ar do not have electronegativities (it is 0)

C - Hydrogen would be the best answer. Looking at the other options here is why:

-Francium has a very large atomic radius, in fact, it has the largest atomic radius. This means that the Electronegativity of Fr would be the lowest.

-Also, even though Uuo's electronegativity is unknown because it's manmade, it would still have a low electronegativity. This is because the atomic radius is larger, which lowers the electronic forces of attraction.
