Describe Ionic Bonding
Correct Answer
D. Ionic Bonding- When a metal combines with a non metal causing the metal to give its electrons to the non metal making both more stable
Explanation
Ionic bonding occurs when a metal and a non-metal combine. In this type of bonding, the metal atom loses its electrons to the non-metal atom, resulting in the formation of positive and negative ions. This transfer of electrons allows both atoms to achieve a more stable electron configuration, similar to that of a noble gas. This electrostatic attraction between the positive and negative ions forms the ionic bond. Therefore, the correct answer is "Ionic Bonding- When a metal combines with a non metal causing the metal to give its electrons to the non metal making both more stable."

Name a Property that Alkali Metals share
Correct Answer
Good conductors of heat and electricity
Most reactive of all metals
Reacts violently with Water and Oxygen
Does not occur in nature in their elemental form
Has 1 electron in its outer energy level
Very reactive
Explanation
Alkali metals are known to be good conductors of heat and electricity. They have a single electron in their outer energy level, making them highly reactive and prone to reacting violently with water and oxygen. Additionally, alkali metals do not occur naturally in their elemental form.
3.
How many valence electrons do all of the metals in Group 2 of the Periodic table have
Correct Answer
B. 2
Explanation
All of the metals in Group 2 of the Periodic table have 2 valence electrons. Group 2 elements, also known as alkaline earth metals, have 2 electrons in their outermost energy level or valence shell. These valence electrons are involved in chemical bonding and determine the reactivity and properties of the elements.
4.
What Metal is the only metal that is Liquid at Room Temperature
Correct Answer
A. Mercury
Explanation
Mercury is the only metal that is liquid at room temperature. This is because mercury has a low melting point of -38.83 degrees Celsius (-37.89 degrees Fahrenheit), which is below typical room temperature. Other metals, such as zinc, gold, europium, and thorium, have higher melting points and are solid at room temperature.
5.
True or False: All Actinides are Radioactive and Stable
Correct Answer
B. False
Explanation
All Actinides are Radioactive BUT all of them are UNSTABLE
6.
Which Non Metal is NOT on the right side of the Periodic Table
Correct Answer
D. Hydrogen
Explanation
Hydrogen is the correct answer because it is a non-metal element that is not located on the right side of the periodic table. In fact, hydrogen is located at the top left corner of the periodic table, in the first group. It is unique because it is the lightest and simplest element, with only one proton and one electron. While most non-metals are located on the right side of the periodic table, hydrogen is an exception to this trend.
7.
Which Elements atoms makes up the majority in the universe
Correct Answer
A. Hydrogen
Explanation
Hydrogen is the correct answer because it is the most abundant element in the universe. It is found in large quantities in stars, including our own sun, and it is also a key component of gas giants like Jupiter and Saturn. Hydrogen is crucial for the formation of stars and galaxies, and it plays a significant role in the processes of nuclear fusion and energy production in stars.
8.
What is a Diatomic Molecule
Correct Answer
E. Not Listed
9.
Where does the word hydrogen come from
Correct Answer
Greek term meaning water forming
Water forming from greek term
Explanation
The word "hydrogen" comes from the Greek term meaning "water forming." This is because hydrogen is the lightest and most abundant element in the universe, and it was originally believed to be a component of water. The term "hydro" refers to water, while "gen" means forming or generating. Thus, the name hydrogen reflects its association with water formation.
10.
What halogen deposits from a gas to a solid quickly
Correct Answer
A. Iodine
Explanation
Iodine is the correct answer because it is a halogen that readily undergoes sublimation, which is the process of transitioning from a gas directly to a solid without passing through a liquid phase. This means that iodine can easily deposit from a gas to a solid quickly. Chlorine, bromine, and fluorine do not undergo sublimation as readily as iodine, making them less likely to deposit quickly from a gas to a solid.
11.
In the Iodine Demo what was the color of the gas
Correct Answer
E. Purple
Explanation
In the Iodine Demo, the color of the gas was purple.
12.
What Traits exist only with noble gases
Correct Answer
Exist as isolated atoms
Stable because outermost energy levels are filled
Do not occur naturally
Stable
Explanation
Noble gases are known for their unique properties. They exist as isolated atoms, meaning they do not form compounds with other elements. This is because their outermost energy levels are completely filled with electrons, making them stable and unlikely to form chemical bonds. Additionally, noble gases do not occur naturally in large quantities on Earth, as they are relatively rare. Overall, these traits make noble gases stable and distinct from other elements in the periodic table.
13.
True or False: Helium is useful in air blimps and balloons because it density is less than airs
Correct Answer
A. True
Explanation
Helium is useful in air blimps and balloons because its density is less than air. This means that helium is lighter than air and provides buoyancy, allowing the blimps and balloons to float.
