4. Which of the following elements is most likely to form a binary ionic compound with chlorine?

Oxygen

Nitrogen

Sodium

Carbon

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.

Explanation

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.

5. In the binary ionic compound MgO, what is the charge on the magnesium ion?

+1

+2

-1

-2

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.

Explanation

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.

6. In the binary ionic compound calcium chloride (CaCl₂), how many chloride ions are present for each calcium ion?

1

2

3

4

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.

Explanation

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.

7. Which of the following is an example of a binary ionic compound?

H₂O

CO₂

NaCl

C₆H₁₂O₆

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.

8. What is the formula for the binary ionic compound formed between aluminum and sulfur?

AlS

Al₂S₃

Al₃S₂

AlS₂

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.

Explanation

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.

9. In binary ionic compounds, the name of the compound is derived from the:

Chemical formula of the compound.

Charge of the anion.

Charge of the cation.

Atomic number of the elements involved.

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.

10. 2 nonmetals chemically combined make a?

Ionic Bond

Covalent Bond

Binary Compound

Sandwich

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.
