In chemistry, the first rule is especially important and is often referred to as simply Hund's Rule.Periodic Law - noun (chemistry) the principle that chemical properties of the elements are periodic functions of their atomic numbersMetals: this is a term that is heard very commonly. Test. Study Flashcards On Chemistry Chapter 1 Notes 1: Introduction to Matter and Measurement at Cram.com. Key Concepts: Terms in this set (30) Atoms consist of - protons (positive)-neutrons (neutral)-electrons (negative) Orbital. Test.
Learn. This number divides the subshell into individual orbitals which hold the electrons; there are 2l+1 orbitals in each subshell.
They can be said to have properties that are quite opposite to that of metals.
Electron is transferred to another atom (breaks easily in water)It's an attraction between two water molecules of opposite attraction, not a bond Created by.
refer to a set of rules formulated by German physicist Friedrich Hund around 1927, which are used to determine the term symbol that corresponds to the ground state of a multi-electron atom. Region of space where an electron can mostly be found . Chemistry Notes. Terms in this set (17) List four quantum numbers and tell the information that each provides about atomic orbitals.

Write. Region of space where an electron can mostly be foundWhen one number is written to the left of the decimal pointAtoms of the same elements that differ in number of neutrons-Because number of protons differs from the number of electronsDepends on instrument, this determines the significant figuresMeasure of how strongly an atom attracts extra electrons to itselfNext strongest bonds, formed when an electron is transferred to another atom. Thus the s subshell has only one orbital, the p subshell has three orbitals, and so on.Specifies the orientation of the spin axis of an electron. Log in Sign up.
Created by. Mass. Nonmetals: non metals are those without the properties of metals. An electron can spin in only one of two directions (sometimes called up and down).The Pauli exclusion principle (Wolfgang Pauli, Nobel Prize 1945) states that no two electrons in the same atom can have identical values for all four of their quantum numbers. They include poor ability to conduct electricity and heat, and are brittle. Cram.com makes it easy to get the grade you want! Learn chemistry notes chapter 2 with free interactive flashcards.

What this means is that no more than two electrons can occupy the same orbital, and that two electrons in the same orbital must have opposite spins.1.theory of element creation: a principle that each successive chemical element in a sequence can be created by adding a proton to the nucleus and an electron to an orbital of the preceding elementthe distance between two points on adjacent waves that have the same phaserate of occurrence: the number of times that something happens during a period of timeaccording to custom or rule or natural law.
Quickly memorize the terms, phrases and much more. The answer is basing on the some of the common properties that are defined for metals.
