Question

Suppose you are trying to find the identity of an unknown pure substance. The valence electrons of the substance's atoms feel an effective nuclear charge of +1. If this substance's atoms have larger radii than potassium (K) atoms, what other characteristics would you expect the substance to exhibit?

Answer 1

It would have higher ionization energies than K and a higher electronegativity value than K.
It would have higher ionization energies than K and a lower electronegativity value than K.
It would have lower ionization energies than K and a higher electronegativity value than K.
It would have lower ionization energies than K and a lower electronegativity value than K.

Answer 2

@Abhisar :)

Answer 3

what do u think ?

Answer 4

The second one. but idk

Answer 5

Why u think it should be B ?

Answer 6

umm cause Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. so should that be lower. And ionization energies is describes the minimum amount of energy so it would be higher. idk

Answer 7

Ionisation energy is the minimum energy required to remove most loosely bounded outermost electron in a ground state from an isolated gaseous state atom.

Answer 8

ionization Energy \(\alpha\) \(\huge\frac{1}{atomic~size}\)

Answer 9

Thank you. but i am eally confused about the question

Answer 10

I think it should be C

Answer 11

I think @Somy will xplain u better

Answer 12

thanks!

Answer 13

The valence electrons of the substance's atoms feel an effective nuclear charge of +1.
this kinda tells me that element is from group 1

Answer 14

atoms have larger radii than potassium (K) atoms
this tells that The element is below K in group 1
because atomic radii increases down the group

Answer 15

electronegativity decreases down the group
so if the element is below K then it is less electronegative

Answer 16

ionization energy also decreases down the group
so that element would have lower ionization energy then K

Answer 17

so i would say its D

Answer 18

yeah okay. Thank you berry much!:)

Answer 19

you are welcome :))
