You find the atoms with the largest atomic radius in the **bottom left corner** of the periodic table. This is because atomic radius generally increases as you move down a group and decreases as you move from left to right across a period.
Answer
A) Which has a higher ionization energy: chlorine (Cl) or magnesium (Mg)? Why? Select the
best answer. (1 point)
Mg; magnesium has more valence electrons than chlorine.
Mg; it takes more energy to pull two electrons away from magnesium(Mg) than it does to take
them from chlorine(Cl).
Cl; it takes much more energy to pull an electron away from a valence shell that is nearly full.
Cl; it takes less energy to add an electron to a valence shell that is nearly full

The correct answer is: **Cl; it takes much more energy to pull an electron away from a valence shell that is nearly full.**
Chlorine (Cl) has a higher ionization energy than magnesium (Mg) because chlorine has a nearly full outer shell with 7 valence electrons, making it more energetically favorable for it to resist losing an electron. In contrast, magnesium has 2 valence electrons and is more willing to lose them to achieve a stable electron configuration. Therefore, it takes more energy to remove an electron from chlorine than from magnesium.

You find the atoms with the strongest metallic properties in the **lower left** corner of the periodic table. Metallic properties are generally strongest in this region because atomic size increases and ionization energy decreases as you move down and to the left, resulting in better conductivity and reactivity typical of metals.
Answer
A) What is unique about how the periodic table of the elements is organized? (1 point)
Elements are in order so that each element has an atomic mass that is 1 greater than the
previous element.
Elements with similar properties are grouped together in a pattern.
Elements are in order according to the number of neutrons in their nucleus.
Elements are grouped by multiples of atomic number.

The unique aspect of how the periodic table of the elements is organized is that **elements with similar properties are grouped together in a pattern.** This organization allows for the prediction of the chemical properties and behaviors of elements based on their position in the table, particularly for elements in the same group or column.

The correct statement about how the Coulomb force affects charge interactions is: **Like charges repel, and opposite charges attract.**
This reflects the fundamental principles of electrostatics, where objects with the same charge (positive or negative) repel each other, while objects with opposite charges attract each other.
