2. What is the name of the compound NaBr?

Explanation

The correct answer is Sodium Bromide. NaBr is the chemical formula for Sodium Bromide, a compound made up of sodium (Na) and bromine (Br) atoms. Sodium bromide is a white crystalline solid that is commonly used in various industries, including pharmaceuticals, photography, and oil drilling.

Submit
3. What is the formula for Sodium Fluoride?

Explanation

The correct answer is NaF, which represents the chemical formula for Sodium Fluoride. Sodium Fluoride is an ionic compound consisting of one sodium ion (Na+) and one fluoride ion (F-). The symbol Na represents the element sodium, while F represents the element fluorine. When these two elements combine, they form Sodium Fluoride, which is commonly used in toothpaste and water fluoridation to prevent tooth decay.

Submit
4. What is the name of the compound KCl?

Explanation

The name of the compound KCl is Potassium Chloride. This is because K represents the element potassium, and Cl represents the element chlorine. When these two elements combine, they form a compound called potassium chloride.

Submit
5. What is the name of the compound CaO?

Explanation

Calcium Oxide is the correct name for the compound CaO. Calcium is a metal and oxygen is a non-metal, so the compound is formed by the combination of these two elements. The name "Calcium Oxide" follows the naming convention for binary compounds, where the name of the metal element (calcium) is followed by the name of the non-metal element (oxide).

Submit
6. What is the formula for Magnesium Oxide?

Explanation

The formula for Magnesium Oxide is MgO. This is because Magnesium (Mg) has a +2 charge, while Oxygen (O) has a -2 charge. In order to balance the charges, one Mg atom combines with one O atom, resulting in the formula MgO.

Submit
7. A crystal of sodium chloride is held together by:

Explanation

Sodium chloride is ionic since sodium is a metal and chlorine is a non-metal. Sodium will transfer one electron to chlorine, forming Na+ and Cl- ions. Ionic compounds are held together by the strong electrostatic forces of attraction between the negative and positive ions.

Submit
8. Which pair of elements will combine to form an ionic compound?

Explanation

An ionic compound is formed between a metal and a non-metal.

Submit
9. Element X has an electronic structure 2, 8, 8, 1. Element Y has an electronic structure of 2, 8, 6. What is the chemical formula of the compound formed between X and Y?

Explanation

Element X can give away 1 electron each. Y needs to gain 2 electrons. Hence, Y needs 2 of element X. Hence, the formula is X2Y.

Submit
10. What is the formula for Lithium Iodide?

Explanation

The formula for Lithium Iodide is LiI.

Submit
11. The atomic number of magnesium is 12. When magnesium reacts to form an ionic compound, the electronic configuration of the magnesium ion formed is

Explanation

Initially, Mg has 12 electrons. When it forms a Mg ion, it loses 2 electrons to achieve a noble gas configuration of 2, 8.

Submit
12. What is the name of the compound HI?

Explanation

The compound HI is named Hydrogen Iodide. This is because it consists of one hydrogen atom bonded to one iodine atom. In chemical nomenclature, the name of a compound is determined by the elements it contains and the ratio in which they are combined. In this case, the compound contains hydrogen and iodine, so it is named Hydrogen Iodide.

Submit
13. How does a magnesium atom form a bond with an oxygen atom?

Explanation

Magnesium will transfer two electrons from itself to an oxygen atom. So that Mg and O both achieve noble gas configuration of 2, 8.

Submit
14. What is the formula for Mercury Oxide?

Explanation

Mercury Oxide is represented by the chemical formula HgO. In this compound, one atom of mercury (Hg) is combined with one atom of oxygen (O). The symbol "Hg" represents the element mercury, while "O" represents oxygen. The subscript "1" is not shown in the formula, as it is understood that there is only one atom of each element in the compound. Therefore, the correct formula for Mercury Oxide is HgO.

Submit
15. What is the formula for Aluminum Nitride?

Explanation

The formula for Aluminum Nitride is AlN.

Submit
16. What is the name of the compound Mg3N2?

Explanation

The compound Mg3N2 is named magnesium nitride because it consists of three magnesium (Mg) atoms and two nitrogen (N) atoms. In chemical nomenclature, the name of an ionic compound is derived from the names of its constituent elements, with the cation (in this case, magnesium) named first and the anion (nitride) named second. Therefore, the correct name for Mg3N2 is magnesium nitride.

Submit
17. What is the name of the compound AlCl3?

Explanation

AlCl3 is the chemical formula for Aluminum Chloride. It is a compound composed of one aluminum atom and three chlorine atoms. Aluminum Chloride is commonly used in various industrial processes, such as in the production of dyes and pharmaceuticals. It is also used as a catalyst in organic reactions and as an electrolyte in batteries. Therefore, the correct answer for the name of the compound AlCl3 is Aluminum Chloride.

Submit
18. What is the formula for lithium hydroxide?

Explanation

The formula for lithium hydroxide is LiOH. The symbol Li represents lithium, and the symbol OH represents the hydroxide ion. The hydroxide ion consists of one oxygen atom and one hydrogen atom, so the correct formula for lithium hydroxide is LiOH.

Submit
19. What is the name of the compound NiO?

Explanation

The correct name for the compound NiO is Nickle (II) oxide. This name follows the naming conventions for binary compounds, where the name of the metal (nickel) is followed by the oxidation state of the metal in parentheses (II) and then the name of the non-metal (oxide).
