A visual representation showing the different parts of a Bunsen burner, such as the air hole, barrel, collar, and gas inlet.

The process of safely lighting a Bunsen burner by first ensuring the air hole is closed, then slowly turning on the gas and using a striker or match to ignite the gas at the top of the barrel.

The blue flame is small and very hot, while the safety flame is larger and yellow.

An atom consists of three components: protons (positively charged), neutrons (neutral charge), and electrons (negatively charged).

The number of protons in the nucleus of an atom, which determines the element’s identity in the periodic table.

A substance composed of only one type of atom, and its symbol is used to represent it in the periodic table.

Metals are typically shiny, malleable, good conductors of heat and electricity, while non

A visual representation of all known elements, where metals are located on the left and center, and non-metals are on the right.

Elements can exist as single atoms (monatomic), in clusters forming molecules (molecular), or in repeating patterns forming lattices (metallic/non-metallic). For example, noble gases are monatomic, oxygen is molecular, and sodium is metallic.

A substance composed of two or more different types of atoms chemically bonded together, forming a new substance with unique properties.

Molecular compounds consist of molecules formed by covalent bonds, while compound lattices are made up of ions held together by ionic bonds.

A representation of the type and number of atoms in a compound, such as H2O for water.

The physical forms in which all matter exists: solid, liquid, and gas, based on the arrangement and energy of particles.

A scientific concept that describes the behavior and properties of particles in different states of matter, including volume, shape, compressibility, flow, and pressure.

The measure of mass per unit volume of a substance, often expressed in grams per cubic centimeter (g/cm3).

Using the displacement method, where the irregular substance is submerged in a known volume of water, and the change in water level is used to calculate the volume of the irregular substance.
