Question

Question 1
A)
Use the periodic table to answer the question.

An illustration shows the periodic table of elements. The elements in the periodic table are arranged in groups (columns numbered 1 through 18) and periods (rows numbered 1 through 7) such that the atomic number increases along a period from left to right. The elements are divided into the following categories: · Alkali metals · Alkaline earth metals · Transition metals · Post-transition metals · Lanthanides · Actinides · Metalloids · Nonmetals · Noble gases · Unknown The elements are also classified on the basis of their physical states as follows: · Solid · Liquid · Gas · Unknown The element sulfur is enlarged with the following properties. · Chemical symbol: S · Name: Sulfur · Atomic Number: 16 · Atomic mass: 32.06 · Common oxidation states: 6, 4, 2, negative 2 · Electronegativity: 2.58 · Ionization energies: 999.589 · Electron configuration: [Ne] 3s2 3p4

Answer 1

Here are the responses to your questions based on the provided information:

**Question 1:**
The element that would most likely lose electrons to form positive ions when bonding with other elements is:
- **rubidium (Rb)**
(Rubidium is an alkali metal, which typically loses one electron to form positive ions.)

---

**Question 2:**
The correct statement about sodium chloride is:
- **The sodium atom transfers electrons to the chlorine atoms to form ionic bonds.**
(Sodium loses an electron while chlorine gains it, resulting in an ionic bond.)

---

**Question 3:**
Based on their locations in the periodic table, the two elements that are most likely to form covalent bonds with each other are:
- **nitrogen (N) and oxygen (O)**
(Both nitrogen and oxygen are nonmetals and are found in adjacent groups on the periodic table, facilitating covalent bonding.)

---

**Question 4:**
The phrase that best describes electronegativity is:
- **the relative strength with which an element attracts electrons in a chemical bond.**
(Electronegativity measures an atom's ability to attract and hold onto electrons.)

---

**Question 5:**
Based on the information in the table, the pair of elements that would likely form the least polar bonds with each other is:
- **bromine and nitrogen**
(Both bromine and nitrogen have relatively close electronegativity values (2.8 and 3.0, respectively), making the bonds between them less polar compared to other pairs listed.)
