Which of the following types of ions is positive?
- A.
Cation
- B.
Anion
Correct Answer
A. CationExplanation
Cations are positively charged ions because they have lost electrons, resulting in an overall positive charge. Anions, on the other hand, are negatively charged ions because they have gained electrons, resulting in an overall negative charge. Therefore, the correct answer is cation.Rate this question:

Which of the following ions is negative?
- A.
Cation
- B.
Anion
Correct Answer
B. AnionExplanation
An ion is an atom or molecule that has gained or lost electrons, resulting in a positive or negative charge. A cation is a positively charged ion, meaning it has lost electrons. On the other hand, an anion is a negatively charged ion, meaning it has gained electrons. Therefore, the correct answer is anion, as it is the ion that carries a negative charge.Rate this question:

Which of the following are properties of ionic compounds
- A.
Low melting temperature
- B.
High boiling point
- C.
Hard
- D.
Brittle
- E.
Electrolyte in water
- F.
Does not conduct electricity in water
- G.
Does not conduct electricity as a solid.
Correct Answer(s)
B. High boiling point
D. Brittle
E. Electrolyte in water
G. Does not conduct electricity as a solid.Explanation
Ionic compounds have high boiling points because the strong electrostatic forces between the positively and negatively charged ions require a significant amount of energy to break the bonds and convert the solid into a liquid. They are brittle because the arrangement of ions in the crystal lattice is easily disrupted, causing the lattice to shatter. Ionic compounds can conduct electricity in water because the ions dissociate in the solution, allowing for the movement of charged particles. However, they do not conduct electricity as a solid because the ions are held in fixed positions and cannot move to carry a current.Rate this question:

The goal of all atoms is to become _____
Correct Answer(s)
Stable, BalancedExplanation
Atoms strive to become stable and balanced by achieving a full outer electron shell. This is because a full outer shell is energetically favorable and leads to a more stable configuration. Atoms can achieve this stability by gaining, losing, or sharing electrons with other atoms through chemical bonding. Once an atom achieves a stable and balanced state, it is less likely to undergo chemical reactions and is considered to be in a more favorable and energetically stable state.Rate this question:

Which will have more lattice energy?
- A.
LiF
- B.
KBr
- C.
NaCl
- D.
RbI
Correct Answer
A. LiFExplanation
Lattice energy is the measure of the strength of the ionic bond in a crystal lattice. It depends on the charges of the ions and their sizes. In LiF, lithium (Li) has a +1 charge and fluoride (F) has a -1 charge. The charges are higher compared to the other compounds listed. Additionally, the size of the ions in LiF is smaller compared to the others. Both the higher charges and smaller size contribute to stronger electrostatic attraction between the ions, resulting in higher lattice energy in LiF compared to the other compounds.Rate this question:

Which would have more lattice energy?
- A.
K2S
- B.
CaO
- C.
GaN
- D.
AlCl3
Correct Answer
D. AlCl3Explanation
AlCl3 would have more lattice energy compared to the other compounds listed. Lattice energy is a measure of the energy released when ions in a crystal lattice arrangement come together to form a solid. It is influenced by factors such as the charge of the ions and their size. In AlCl3, aluminum (Al) has a +3 charge and chlorine (Cl) has a -1 charge, resulting in a strong electrostatic attraction between the ions. Additionally, the smaller size of aluminum and chlorine ions compared to the other ions listed further enhances the lattice energy in AlCl3.Rate this question:

How many Valence Electrons does Chlorine have?
Correct Answer
7Explanation
Chlorine has 7 valence electrons. The number of valence electrons is determined by the group number of the element in the periodic table. Chlorine is in group 17, also known as the halogens, which means it has 7 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom and they play a crucial role in determining the chemical properties of an element.Rate this question:

What is Zinc's oxidation number ALWAYS?
Correct Answer
+2Explanation
Zinc's oxidation number is always +2 because it is a transition metal with two valence electrons. Transition metals typically lose these two electrons to form a stable +2 oxidation state. This is because the loss of these electrons fills the d orbital, resulting in a more stable configuration. Therefore, regardless of the compound or reaction, zinc will always have an oxidation number of +2.Rate this question:
- 23.
What is Sodium's Oxidation number?
Correct Answer
+1Explanation
The oxidation number of an element represents the number of electrons that an atom can gain, lose, or share when it forms compounds. In the case of sodium, it belongs to Group 1 of the periodic table, which means it has one valence electron. Sodium readily loses this electron to achieve a stable electron configuration, resulting in an oxidation number of +1. This is because the loss of one electron gives sodium a complete outer shell, similar to the noble gas configuration of neon.Rate this question:

When drawing lewis structures what do all of the ions need to have around it?
- A.
Brackets
- B.
Charges
- C.
Full Valence Shells
- D.
The center atom always having 8 VE
Correct Answer(s)
A. Brackets
B. ChargesExplanation
When drawing Lewis structures, all ions need to have brackets and charges around them. Brackets are used to enclose the ion and indicate that it carries a charge. Charges are necessary to represent the overall charge of the ion. This helps in accurately representing the electron distribution and understanding the bonding and structure of the compound.Rate this question:
