Part One: Bonding and Lattices
Elements, such as minerals, consist of molecules and atoms. Atoms may exist independently, such as in noble gases, or interconnected, such as in solids. Minerals are solid elements that are composed of chemically bonded atoms known as lattices (Stile Education, 2016). For instance, salt is a mineral that consists of lattices made of Na+ and Cl- atoms (Holton, 2016). Additionally, mineral lattices are made of particles that can be grouped as ions and cations (Khan Academy, 2016). In your opinion, what are minerals crystals made of scientifically? How can one transform minerals from their solid nature to other forms?
Part two: Properties of minerals
Minerals have various unique properties that distinguish them from other solids. First, they are inorganic and must exist naturally in solid form. Additionally, they have fixed chemical formulas that are arranged in orderly crystalline structures (Sammartano, 2013). Minerals also have a varying degree of hardness that is measured on a scale of 1 to 10. For instance, talc has a hardness scale of 1, while diamonds have a hardness measure of 10 (Janux, 2014). Finally, minerals have unique colors that form different streaks when scratched on hard surfaces (Sammartano, 2019). In your opinion, how would you use the properties of minerals to identify their uses?

Part 3: Code of Ethics
Codes of ethics are essential in the medical field to regulate the behaviors of practitioners and researchers. A researcher would execute accountability, integrity, professional commitment, and respect for the dignity, worth, equality, diversity, and privacy of individuals when conducting a study that requires patient participation (World Health Organization, n.d.). For instance, if a scientist who used patient data without disclosing the source observed the ethical guidelines provided by WHO. Where else would a scientist need to act ethically?
