QuestionAnswer
The filled outer electron level configuration can be written as what? ns(superscript 2)np(superscript 6)
The eight electrons in the outer energy level fill what orbitals? s and p
In most chemical reactions, atoms tend to match the s and p electron configurations of the noble gases. What is this tendency called? The octet rule
Based on the octet rule, an atom whose outer s and p orbitals do not match the electron configurations of a noble gas will do what? They will react to lose or gain electrons so the outer orbitals will be full
Alakai metals are in what group? Group 1
Alakine-earth metals are in what group? Group 2
Transition metals are in what groups? 3, 4, 5, 6, 7, 8, 9, 10, 11, 12
Noble Gases are in what group? 18
The Halogens are in which group? 17
Are the Halogens reactive? yes
After reacting, an element becomes what? stable
The superscripts in an electron confiuration ([Mg] + [Ne]3s (superscript 2) ) added together tell how many ________ an atom has. valence electrons
A potassium will lose one valence electron to have the electron configuration of a noble gas instead of gaining 7 valence electrons because ...? it requires less energy
All atoms are uncharged because they have...? equal numbers of protons and electrons
After giving up an electron to become stable, an atom will have an uneven number of protons and neutrons, causing there to be a...? net electrical charge
An atom, radical, or molecule that has gained or lost one or more electrons and has a negative or positive charge is called a(n) ion

Group 1 metals are extremely ______? reactive
when an ionic bond is formed, what two things attract one another? cations and anions
The energy released when ionic bonds are formed is called the ...? lattice energy

Salts are excellent ________ conductors. Electrical
____ means that the crystal is able to resist a large force applied to it. Hard
_________ means that when the applied force becomes too strong to resist, the crystal develops a widespread fracture rather than a small dent. brittle
hardness and brittleness can both be attributed to the way ______ and _______ are arranged in all salt crystals. cations and anions
a ________ ___________ is the regular pattern in chich a crystal is arranged. crystal lattice
