-
From: GradeBuddy Pages: 2A region of characteristic shape and energy where electrons in a molecule are located.
-
From: GradeBuddy Pages: 2A model predicting the arrangement of valence electron electron pairs around a central atom that minimizes their mutual repulsion to produce the lowest energy orientations.
-
From: GradeBuddy Pages: 2VSEPR applies this principle by assuming that pairs of valence electrons are arranged about central atoms in ways that minimize repulsion between the pairs
-
From: GradeBuddy Pages: 2An odd-electron molecules with an unpaired electron in its Lewis Structure.
-
From: GradeBuddy Pages: 2The octet rule and Lewis structures to explain the composition of many common ionic compounds.
-
From: GradeBuddy Pages: 2Lewis developed a system of symbols to explain the number of chemical bonds an atom typically forms to complete its octet.
-
From: GradeBuddy Pages: 2Elements that make up all the matter in our world.
-
From: GradeBuddy Pages: 3The size of the atoms or ions making up any substance influences both physical and chemical properties of the substance.
-
From: GradeBuddy Pages: 2The principle quantum number n is like Boher's quantum number n for the hydrogen atom in that it is a positive integer that indicates the relative size and energy of an orbital or a group of orbitals in an atom.
-
From: GradeBuddy Pages: 5This is a cooperative assignment to work with other students. It will not be collected or graded. You should be able to answer all questions on this worksheet without reference to your text, lab manual, or notes. But this worksheet should not be your sole study material.
-
From: GradeBuddy Pages: 2An electron will preferentially occupy the lowest energy orbital available. The single electron in a hydrogen atom occupies the orbital with n=1, l=0, m=0 (the 1s orbital).
-
From: GradeBuddy Pages: 4If a substance absorbs light energy, it has to absorb a whole number of photons. If a substance emits light energy, it has to emit a whole number of photons. The energy is quantized.
-
From: GradeBuddy Pages: 2Describe the wavelike and particle like properties of electromagentic radiation.
-
From: GradeBuddy Pages: 2A model that describes the behavior of gasses, all equations defining relationships between pressure, volume, temperature, and number of moles of gases can derived from the theory.
-
From: GradeBuddy Pages: 2Enthalpy values referenced to this zero point are the standard enthalpies of formation (ΔH°f ).
-
From: GradeBuddy Pages: 2The experimental method of ,measuring the quantities of energy associated with chemical reaction and physical changes.
-
From: GradeBuddy Pages: 2the substances currently under examination. In chemistry, it is the reactants and products of a chemical reaction.
-
From: GradeBuddy Pages: 2Energy basic concepts and definitions work, potential energy and kinetic energy.
-
From: GradeBuddy Pages: 2Balancing Redox reactions that involve hydroxide ions.
-
From: GradeBuddy Pages: 2One of the two halves of an-oxidation-reduction reaction; one half-reaction is the oxidation component, and the other is the reduction component.
