Chemistrysmallest part of an element that can be identified as that elementsubstance that CANNOT be chemically broken down into simpler substancescenter, or core, of an atom (where the protons and neutrons are located)particle that has a positive charge - located in the nucleus of an atom. You can figure out the number of protons by looking at the atomic number of an cle that has no charge - located in the nucleus of an atom. You can figure out the number of neutrons by SUBTRACTING the atomic Ma...

Chemistry Periodic Table QuizWhat's the purpose of the periodic table? to organize the elements What two properties are the modern periodic table based upon? electron configuration and atomic number 00:12 01:22 What two men are credited with the development of the first periodic tables in 1869? Mendeleev and Meyer What was Mendeleev's table based upon? chemical and physical properties Why is the table called the periodic table? properties occur periodically What does Medeleev's periodic law s...

Chemistry 20compound a pure substance formed from atoms two or more elements with the same limited resources. ionic compound a pure substance formed by a non-metal and a metal. Covalent bond a bond formed by the simultaneous attraction of two nuclei for a shared pair of electrons. Molecular compound a pure substance form by non-metals. concentrated solution a solution containing a high ratio of solute to solution. Mole Ratio the ratio of the coefficients in a balanced chemical equation. Qualitat...

Chemistry of Lifepolar describes a molecule with opposite charges on opposite ends non-polar molecule that shares its electrons equally; does not have areas of charge acid compound that forms hydrogen ions (H+) in solution base compound that produces hydroxide ions (OH-) in solution pH scale measurement system used to indicate the concentration of hydrogen ions (H+) in solution; ranges from 0 to 14 protein macromolecule that contains carbon, hydrogen, oxygen, and nitrogen; needed by the body for...

Intro to Chemistry flashcardsmatter anything that has mass and takes up space physical property characteristic of a substance observed without changing it into another substance 00:41 01:22 solid definite shape and definite volume liquid definite volume but indefinite shape gas indefinite shape, indefinite volume plasma state of matter that occurs when energy such as electricity or heat is applied to a gas. mass amount of matter in an object volume the amount of space an object takes up density ...

Atomic Radius half the distance between adjacent nuclei or bonded nuclei *no defined edge of atom because of electron cloud- can't measure from edge Atomic Radius- Period Trend -left to right decrease -increase in number of protons and valence electrons but same energy level; no further shielding so stronger nuclear pull Atomic Radius- Group Trend -going down atomic radius increases -there are more energy levels causing more shielding and less nuclear pull Ion a charged atom; formed when giving...
