Question
1. Sulfur has atomic number 16 and most sulfur atoms have an atomic mass of 32.
How many protons does the average sulfur atom have? ______
How many neutrons does the average sulfur atom have? ______
How many electrons does the average sulfur atom have? ______
2. Two other elements in the same period as Nitrogen (N) are _______, and ________.
3. Two other elements in the same group as Nitrogen (N) are _______, and ________.
4. Oxygen has _______ valence electrons. (Highlight the correct answer in each set of parentheses.)
To have a complete outer shell it will most likely (gain / lose) two electrons.
This will give it a ( +2 / -2 ) charge.
5. What is an isotope?
6. How many valence electrons do the following elements have?
Li: ______ Ca: _____ B: _____ Se: _____
7. If Lithium and oxygen were placed together - predict what most of it would form (circle or highlight one of the choices below):
LiO (Lithium monoxide) Li2O (Lithium Oxide) or Li2O2 (Lithium peroxide)
8. Explain why the choice you picked above is the correct one. Explain simply

1.
- The average sulfur atom has **16** protons.
- The average sulfur atom has **16** neutrons (32 atomic mass - 16 protons = 16 neutrons).
- The average sulfur atom has **16** electrons.
2. Two other elements in the same period as Nitrogen (N) are **Carbon (C)**, and **Oxygen (O)**.
3. Two other elements in the same group as Nitrogen (N) are **Phosphorus (P)**, and **Arsenic (As)**.
4. Oxygen has **6** valence electrons.
To have a complete outer shell it will most likely **gain** two electrons.
This will give it a **-2** charge.
5. An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons, resulting in a different atomic mass.
6.
- Li: **1**
- Ca: **2**
- B: **3**
- Se: **6**
7. If Lithium and oxygen were placed together - predict what most of it would form: **Li2O (Lithium Oxide)**.
8. I picked **Li2O (Lithium Oxide)** because lithium has 1 valence electron and oxygen has 6 valence electrons. To achieve a stable electronic configuration, two lithium atoms are needed to donate their 1 electron each to oxygen, giving it a total of 2 electrons. This results in the formula Li2O for Lithium Oxide.
