Question

For which of the following properties does sodium have a larger value than rubidium? Select all that apply.

Ionization energy

None

Atomic radius

Electronegativity

Answer 1

Answer:

Ionization energy

Electronegativity

Explanation:

-due to its smaller ionic radius....the electron in the outter most shell tends to expierence a stronger nuclear attraction...which makes it harder to remove the electron from the sodium atom

-Rubidium has lesser ionization energy because its (i) affected by its larger ionic radius which tends to lessen the nuclear attraction ...hence making it easier to remove the electron...(ii)and also by the screening effect done by the inner shells, which also tends to lessen the nuclear attraction.

Sodium has a higher electronegativity than rubidium;

Electronegativity is the charge density of electrons in an atom...in which its high when the atomic radius is smaller...

So hence due to the sodium atomic radius being smaller...it tends to have a higher charge density than rubidium....which then gives it a higher electronegativity value

Answer 2

The  following properties are given below :

* Ionization energy

*Electronegativity

Electronegativity is the charge density of electrons in an atom, which increases when the atomic radius is small.

Therefore, because sodium has a small atomic radius, it tends to have a higher charge density than rubidium and has a higher electronegativity value.

What is Ionization energy?

This is the energy that an atom absorbs and emits an electron. Metals have fairly low ionization energies until they develop a noble gas electron configuration.

What is Electronegativity?

This is a chemical property that describes the tendency of an atom or functional group to attract an electron.
