There are several career paths for chemists including biochemists, analytical chemists, and forensic chemists. Biochemists study chemical processes in living organisms and work in fields like biotechnology, medicine, food/drug industries, and agriculture. Analytical chemists use various techniques to identify and quantify substances and may work in chemical analysis, product development, and quality control. Forensic chemists apply chemistry to law enforcement by solving crimes through analyzing evidence and remains.

1. The document discusses the contributions of several important scientists to the development of chemistry and the periodic table of elements.
2. Key scientists mentioned include Antoine Lavoisier who established modern chemistry through discoveries like the law of conservation of mass and the role of oxygen, John Dalton who developed atomic theory and proposed that elements are made of atoms, Henry Moseley who helped organize the periodic table based on atomic numbers, Ernest Rutherford who discovered the nuclear model of the atom.
3. Other scientists summarized are Dmitri Mendeleev who created one of the first versions of the periodic table and predicted properties of undiscovered elements, Lothar Meyer who developed one of the first periodic tables organizing elements by atomic weightCareers in chemistry

Molecular formulaMoshe Lacson
Ìý
This document discusses concepts related to stoichiometry including empirical formulas, molecular formulas, percentage composition, and hydrates. It provides examples of calculating empirical formulas from mass percentages of elements in compounds and using mole ratios. It also distinguishes between empirical formulas that give the lowest whole number ratio of atoms in a compound and molecular formulas that give the actual ratio in compounds.Electronic configuration
Electronic configurationMoshe Lacson
Ìý
The document discusses the electronic configuration of atoms, which is the arrangement of electrons in an atom's orbitals. It defines the key terms of energy levels and sublevels, which are the orbitals where electrons are arranged. Examples of electronic configurations are given for several elements, such as iodine and silicon. Rules for determining electronic configuration, such as Aufbau's principle, Pauli's exclusion principle, and Hund's rule are also outlined.

Branches in chemistryMoshe Lacson
Ìý
There are several main branches of chemistry including analytical chemistry, organic chemistry, inorganic chemistry, physical chemistry, biochemistry, nuclear chemistry, and materials chemistry. Analytical chemistry involves the separation, identification, and quantification of chemical components. Organic chemistry is the study of carbon-containing compounds. Inorganic chemistry covers non-organic compounds including minerals, salts, and water. Physical chemistry examines the physical and theoretical properties of chemical systems. Biochemistry studies chemistry in living organisms. Nuclear chemistry deals with radioactive elements and processes. Materials chemistry prepares and analyzes functional substances.Introduction to chemistry
Introduction to chemistryMoshe Lacson
Ìý
Chemistry is the science of matter and the changes it undergoes during chemical reactions. It studies the composition, behavior, structure and properties of matter. The origins of the term chemistry come from various ancient words related to casting, alloying metals, and transmuting earth. Chemistry is a natural science that includes branches like organic chemistry, inorganic chemistry, biochemistry, physical chemistry, and analytical chemistry. Ancient civilizations like Greeks, Indians and Egyptians applied early forms of chemistry as early as 1000BC by purifying metals, dyeing cloth, brewing wine, and making medicines and alloys, though they did not realize it as chemistry. The discovery of alloys marked the start of the Bronze Age around 3300BCMore Related Content
