What is the scientific method, and how is it used in chemistry?
✔✔ The scientific method is a systematic approach to research that involves making
observations, forming a hypothesis, conducting experiments, analyzing data, and drawing
conclusions. In chemistry, it is used to investigate chemical phenomena and develop new
theories or technologies.
What distinguishes a chemical change from a physical change in matter?
✔✔ A chemical change involves a transformation that alters the chemical composition of a
substance, resulting in the formation of new substances with different properties. A physical
change affects the form or appearance of a substance without changing its chemical composition.
How are elements and compounds defined in chemistry?
✔✔ Elements are pure substances that consist of only one type of atom and cannot be broken
down into simpler substances by chemical means. Compounds are substances composed of two
or more different elements chemically bonded together in fixed proportions.

, What is the significance of the atomic number in the periodic table?
✔✔ The atomic number represents the number of protons in the nucleus of an atom and
determines the element's position on the periodic table. It also defines the identity of the element.
How do isotopes of an element differ from one another?
✔✔ Isotopes of an element have the same number of protons but different numbers of neutrons
in their nuclei, resulting in different atomic masses.
What is the role of electrons in determining the chemical properties of an atom?
✔✔ Electrons, particularly those in the outermost energy level (valence electrons), determine an
atom's chemical reactivity and bonding behavior.
How is the concept of the mole used in chemical calculations?
✔✔ The mole is a unit that quantifies the amount of substance. It is used to relate the number of
particles (atoms, molecules, ions) to the mass of a substance and to perform calculations
involving chemical reactions and stoichiometry.
What is the difference between accuracy and precision in experimental measurements?
