Question 2
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

Here are the correct answers to your questions:
**Question 1:**
A) **Which property do the elements in each column of the representative elements series of the periodic table have in common?**
- **Response:** **number of valence electrons**
**Question 2:**
A) **Which element has six valence electrons?**
- **Response:** **sulfur (S)** (None of the provided answers were correct based on the question statement; the correct response would be sulfur, but since it's not listed, the closest would be oxygen (O) which has 6 in its outermost shell.)
**Question 3:**
A) **Which of the following defines the atomic number of an atom?**
- **Response:** **the number of protons**
**Question 4:**
A) **Potassium’s atomic number is 19, and its atomic mass is approximately 39. How many neutrons does potassium have?**
- **Response:** **20** (Calculated as Atomic mass - Atomic number = 39 - 19 = 20)
**Question 5:**
A) **Which element does not have the same number of electrons in its outermost shell as the other elements in its group?**
- **Response:** **hydrogen (H)** (Hydrogen is in group 1 but only has one electron, while all other alkali metals have one electron in their outer shell too, but this question can depend on the specific group being referenced.)
If you need further clarification or additional information, feel free to ask!
