What all periodic trends are based on
What is attraction between the nucleus (protons) and electrons
100
The ion formed when an atom gains an electron

Organized by increasing atomic number
What is the modern periodic table
200
The "B" group elements
What is the Transition Metals
200
The element with the configuration ending in 2s1
What is Lithium
200
An atom or group of atoms that has a positive or negative charge
What is an ion
200
The ion formed when at atom loses an electron
What is a cation
300
What groups of elements share
What is similar chemical and physical properties
300
Group 1A, 2A, 7A
What is Alkali metals, Alkaline earth metals, Halogens
300
The group of elements ending in the configuration np6
What is the Noble gases
300
The ability of an atom of an element to attract electrons when the atom is in a compound
What is electronegativity
300
The energy required to remove an electron
What is ionization energy
400
Corresponds to a principal energy level
What is each period
400
For these elements the group number equals the number of electrons in the highest occupied energy level
What is the Representative Elements
400
The element ending with the configuration 5s24d8
What is Palladium
400
Based on their position on the periodic table, between chlorine and bromine, which atom has the smaller atomic radius ?
What is chlorine
400
Based on their position on the periodic table, between lithium and sulfur, which atom has the highest first ionization energy?
What is sulfur
500
DAILY DOUBLE!! When elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties
What is Periodic Law
500
For these elements the highest occupied s sublevel and a nearby d sublevel contain electrons
What is the Transition Elements
500
The element ending with the configuration 7s25f11
What is Einsteinium
500
The reason ionization energy for representative elements tends to increase from left to right across a period.
What is as you add electrons to the same energy level, electron shielding remains the same and there is an increase in the attraction of the nucleus for electrons
500
The reason electronegativity decreases from top to bottom within a group
What is as atomic size increases, electron shielding increases and there is a decrease in the attraction of the nucleus for electrons
