What would be the properties of an atom with a really high ionization energy?

Not sure how many you’re looking for, but it has a high effective nuclear charge and its valence electrons are close to the nucleus. As a result, its atomic radius is generally small in comparison to other elements.

Kinda what I was looking for. I was looking for the really simple answer of that atom not wanting to give away its electron but I probably should have specified. Your turn to ask a question!

1. What is the trend of the atomic radius in the period of a periodic table? Why is this so?
2. Briefly explain why elements like oxygen and fluorine have high electronegativity.
3. When balancing a redox reaction in an acidic solution, what do you balance H2O with?

I can answer the first two for now
1. As atomic radius goes across a period, it decreases because of the stronger pull on the electron cloud but increases across due to shielding effect or more shells.
2. Elements like Oxygen and Flourine tend to have high electronegativity because of their desire to gain more electrons and act like noble gases with a full valence shell(8).
* hope this helps*

In the future, make sure to hide your answers. Your first two answers are correct, though!
