iren [92.7K]

Answer:

I just did the assignment it's "decreases"

Explanation:

If you guys came from Ed-genuity (i'm writing it like that because apperantly that is a swear word?) That means the next questions are "As you move from left to right across the periodic table, electronegativity..." and "As you move from top to bottom within a group, the first ionization energy...".

for electronegativity, it's increases and for ionization energy it's decreases. Hope this helps!

Elements donate 2 electron to produce a cation with a 2+ charge
hammer [34]

Answer: alkaline earth metals (group-IIA)

Explanation:

The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.

Alkaline earth metals donate 2 valence electrons to acquire noble gas configuration.

For example: Berrylium is the first alkaline earth metal with atomic number of 4 and thus has 4 electrons

Electronic configuration of berrylium:

[Be]:4:1s^22s^2

Berrylium atom will loose two electrons to gain noble gas configuration and form berrylium cation with +2 charge.

[Be^{2+}]:2:1s^2

Thus Elements donate 2 electron to produce a cation with a 2+ charge are alkaline earth metals.
