Elements, Compounds & Mixtures + Chemical Formulas Homework 🧪

📅 Assigned: February 3 | Due: February 4

This assignment focused on understanding elements, compounds, and mixtures, as well as how to read and interpret chemical formulas using subscripts, coefficients, and element symbols.

What You Did:

1️⃣ Elements, Compounds & Mixtures Homework

• Defined the terms element, compound, and mixture.

• Compared and contrasted their similarities and differences.

• Created visual models to represent each using shapes.

2️⃣ Lewis Dot Diagrams Homework

• Explained what a Lewis Dot Diagram represents.

• Identified valence electrons and which elements have a full outer shell.

• Drew Lewis Dot Diagrams for elements like oxygen, silicon, lithium, and boron.

3️⃣ Writing Chemical Formulas Homework

• Completed sentences using terms like formula, letters, numbers, parentheses, and structure.

• Identified elements and the number of atoms in common chemical formulas such as fructose, caffeine, and magnesium bicarbonate.

• Explained how two different substances (fructose and glucose) could have the same chemical formula but different structures.

4️⃣ Counting Atoms & Color Activity

• Reviewed key vocabulary including subscripts, coefficients, and parentheses in chemical formulas.

• Determined the number of atoms in various formulas.

• Used these values to color a coded image based on correct answers.

Why This Matters:

These concepts are essential for understanding chemical reactions, molecular structures, and the properties of different substances. By practicing these skills, you are building a strong foundation for more advanced chemistry topics! 🧬🔥
