True or False: The proccess of when an atom GAINS electrons to become an ion, is called Ionization.
-
True
-
False
Correct Answer
A. FalseExplanation
The process of when an atom GAINS electrons to become an ion is actually called reduction, not ionization. Ionization refers to the process of when an atom or molecule loses or gains electrons to form ions.Rate this question:

Ionization energies generally _____________ as you move from left to right across a _________
Correct Answer
Increases
PeriodExplanation
As you move from left to right across a period, the ionization energies generally increase. This is because the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons in the outermost energy level. As a result, more energy is required to remove an electron, resulting in higher ionization energies.Rate this question:

Nuclear charge is ....
-
The increased hold on the valence electrons
-
The energies that generally increase as you move from left to right on a period
-
When electricity is plugged in a nuclear plant and charged until 100%
-
The total charge of all protons in the nucleus
Correct Answer
A. The total charge of all protons in the nucleusExplanation
Nuclear charge refers to the total charge of all protons in the nucleus of an atom. Protons carry a positive charge, and their total charge determines the overall charge of the nucleus. This charge influences the behavior of the valence electrons and the energies of the electrons in an atom. As the number of protons increases, the nuclear charge also increases, leading to a stronger attraction between the nucleus and the valence electrons. This increased hold on the valence electrons is responsible for the energies that generally increase as you move from left to right on a period in the periodic table.Rate this question:

As you go down a group, atoms have more total _________electrons, so they don't really care that much about their outermost ones.
Correct Answer
inner, InnerExplanation
As you move down a group (vertical column) in the periodic table, atoms have more electron shells, increasing the distance between the outermost electrons (valence electrons) and the positively charged nucleus. This greater distance reduces the attractive force between the nucleus and the valence electrons, making them less tightly held and more likely to participate in chemical reactions.Rate this question:
