a pattern of similar properties can be seen” PERIODIC LAW • When elements are arranged by Atomic number their chemical and physical properties recur periodically TERMS • Periods: a row in the periodic table (left to right) • Groups: a column in the periodic table (top to bottom) CO...
less negative Ea In general, atoms with filled or half-filled subshells have more positive electron affinities than do elements on either side of them in the periodic table N:1s22s22p3 O:1s22s22p4 n = 2, Z eff = 5 n = 2, Z eff = 3 1s2 2s2 1s2 2s2 2p1 These 2e- repel ...
Trends in the Periodic Table Date: Per.: 1. anizationA. A horizontal row in the Periodic Table is called a .B. A vertical column in the Periodic Table is called a or .2. OrbitalsA. Identify the orbitals being filled in the following periods (period 4 is done for you as an example...
The Nitrogen family, the Carbon family and the Boron family are found in the p-block of the Periodic Table. The Nitrogen family is group 13, while the Carbon family is group 14 and the Boron family is group 15. All of the elements in the Nitrogen, Carbon and Boron families have unique...
the trend!atomic radius increaseswhy?ACROSS: electrons added to the same energy level experience increasing attraction due to addition of protonsDOWN:each period on the table adds a new energy level to the electron cloudpracticesort the following from largest to smallest:Ca, Mg, and SrSr >...

PeriodicTrends.ppt,Periodic Trends OBJECTIVES: Interpret group trends in atomic radii, ionic radii, ionization energies, m.p., b.p., electronegativity and chemical properties Trends in Atomic Size First problem: Where do you start measuring from? The ele
Periodic Trends Atomic Radius Definition: Half of the distance between nuclei in covalently bonded diatomic molecule Radius decreases across a period Increased effective nuclear charge due to decreased shielding Radius increases down a group Each row on the periodic table adds a “shell” or energy ...
The Periodic Table and Atomic Radius Example: Which is larger: a lithium atom or a fluorine atom? Example: Which is larger: an arsenic atom or a sulfur atom? Part II – Ionization Energy Ionization energy Ionization energy is the amount of energy needed to remove an electron from a gaseous...
