2 nonmetals chemically combined make a?
- A.
Ionic Bond
- B.
Covalent Bond
- C.
Binary Compound
- D.
Sandwich
Correct Answer
B. Covalent BondExplanation
When two nonmetals chemically combine, they typically form a covalent compound or molecule. In a covalent compound, the nonmetals share electrons to achieve a stable electron configuration. This sharing of electrons allows them to bond together and create a molecule, rather than forming ionic bonds typically seen in compounds involving metals and nonmetals.Rate this question:

In binary ionic compounds, the name of the compound is derived from the:
- A.
Chemical formula of the compound.
- B.
Charge of the anion.
- C.
Charge of the cation.
- D.
Atomic number of the elements involved.
Correct Answer
A. Chemical formula of the compound.Explanation
In binary ionic compounds, the compound's name is derived from its chemical formula, which consists of a cation (positively charged ion) and an anion (negatively charged ion). The name reflects the combination of these ions, with the cation named first followed by the anion, preserving electrical neutrality.Rate this question:

- What prefix name for 2?
- A.
Zwei
- B.
Di
- C.
Penta
- D.
Tri
Correct Answer
B. DiExplanation
The prefix "Di" is the correct answer for the question "What prefix name for 2?" This is because "Di" is commonly used as a prefix to indicate the number 2 in various contexts, such as in words like "dioxide" or "dilemma".Rate this question:

What is the chemical formula for Triselenium Hexachloride?
- A.
Se3Cl6
- B.
SeCL
- C.
Se6Cl3
- D.
SeCl1
Correct Answer
A. Se3Cl6Explanation
The chemical formula for Triselenium Hexachloride is Se3Cl6. This is because "tri" indicates that there are three selenium atoms present, and "hexa" indicates that there are six chlorine atoms present. Therefore, the correct formula is Se3Cl6.Rate this question:

Which of the following is an example of a binary ionic compound?
- A.
H₂O
- B.
CO₂
- C.
NaCl
- D.
C₆H₁₂O₆
Correct Answer
C. NaClExplanation
Sodium chloride (NaCl) is a binary ionic compound consisting of sodium (a metal) and chlorine (a non-metal). Sodium donates one electron to chlorine, resulting in the formation of Na⁺ and Cl⁻ ions. The other options are covalent compounds composed of non-metals.Rate this question:

In the binary ionic compound MgO, what is the charge on the magnesium ion?
- A.
+1
- B.
+2
- C.
-1
- D.
-2
Correct Answer
B. +2Explanation
Magnesium (Mg) is an alkaline earth metal in Group 2 of the periodic table. It loses two electrons to form a Mg²⁺ ion with a +2 charge. In MgO, this Mg²⁺ ion pairs with an O²⁻ ion, resulting in a neutral compound.Rate this question:

Which of the following elements is most likely to form a binary ionic compound with chlorine?
- A.
Oxygen
- B.
Nitrogen
- C.
Sodium
- D.
Carbon
Correct Answer
C. SodiumExplanation
Sodium (Na) is an alkali metal with a tendency to lose one electron and form a Na⁺ ion. Chlorine (Cl) is a non-metal that gains one electron to form a Cl⁻ ion. Together, they form sodium chloride (NaCl), a typical binary ionic compound. The other elements listed either form covalent compounds or do not easily form stable ionic bonds with chlorine.Rate this question:

What is the formula for the binary ionic compound formed between aluminum and sulfur?
- A.
AlS
- B.
Al₂S₃
- C.
Al₃S₂
- D.
AlS₂
Correct Answer
B. Al₂S₃Explanation
Aluminum (Al) forms a +3 ion (Al³⁺), and sulfur (S) forms a -2 ion (S²⁻). To balance the charges, two aluminum ions (total +6) combine with three sulfur ions (total -6) to form Al₂S₃, a neutral binary ionic compound.Rate this question:

In the binary ionic compound calcium chloride (CaCl₂), how many chloride ions are present for each calcium ion?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
B. 2Explanation
Calcium (Ca) forms a Ca²⁺ ion with a +2 charge, and chlorine (Cl) forms a Cl⁻ ion with a -1 charge. To balance the charges in calcium chloride, one Ca²⁺ ion pairs with two Cl⁻ ions, resulting in the formula CaCl₂.Rate this question:
