100
The energy change associated with the gaining of an electron by the atom or ion in the gaseous state.
What is electron affinity?
100
An ion with a positive charge.
What is a cation?
100
This bond involves the sharing of electrons between two nonmetals.
What is a covalent bond?
100
Factors effecting potential energy.
What is ionic charge and distance between nucleus's?
100
In order of increasing metallic character: Si, Cl, Na, Rb.
What is Cl<Si<Na<Rb
200
Elements that are good conductors of heat and electricity, are malleable, ductile, and shiny, and tend to lose electrons in chemical reactions.
What are metals?
200
A nonmetal bonded to a metal becomes this type of ion.
What is an anion?
200
This bond involves a metal and a nonmetal and the transfer of electrons.
What is an ionic bond?
200
Which compound has the lattice energy of greatest magnitude, NaCl or MgCl2?
What is MgCl2?
200
Reason SrO has a more exothermic lattice energy than KBr.
What is ionic charge?
300
As you move down column 1A on the periodic table the number of energy levels increases, increasing the distance of the outermost electron from the nucleus. This causes certain properties to decrease.
What is electron affinity and ionization energy?
300
An element that will tend to lose exactly 2 electrons. (Name any)
What is (anything from group 2)?
300
The sharing or transfer of electrons to attain a stable electron configuration.
What is a chemical bond?
300
Correct formula for compound formed between Calcium and Chlorine.
What is CaCl2?
300
Largest Radius: Cl- , K+, S-2, Ca+2
What is S2- ?
400
A property responsible for the decrease in atomic radius as you move to the right of the periodic table.
What is the effective nuclear charge?
400
The potential energy of two bonded atoms will be negative and will become more negative as they get closer together (r decreases) when they are of these charges.
What are opposite charges?
400
The most stable number of electrons in the outermost shell for most atoms is defined by a rule.
What is the octet rule?
400
Formula for compound that forms between magnesium and nitrogen?
What is Mg3N2?
500
An increased ionic radius will have this affect on the lattice energy.
What is less exothermic/less negative?
500
The energy associated with the forming of a crystalline structure from alternating cations and anions.
What is lattice energy?
500
Electronic configuration of O-2.
What is 1s2s2p6?
500
Your SI leader's name.
