100
outer most shell that contains electrons
What is valence shell?
100
An atom that has a net electric charge
What is an ion?
100
electric force of attraction between two oppositely charged ions
What is an ionic bond?
100
this type of electrical attraction in which atoms are held together by their mutual attraction for shared electrons
What is a covalent bond?
100
a separation of electric charge that occurs in a chemical bond because of differences in the electronegativities of the bonded atom
What is a dipole?
200
notation used to represent electrons in the outer shell
What is electron dot structure?
200
a neutral atom that loses electrons
What is a positive ion?
200
a chemical compound that contains two or more ions

What is hydrogen?
200
when two atoms have the same electronegativity, no dipole is formed and the bond is classified as this
What is a nonpolar bond?
300
when 2 electrons refuse to form a chemical bond they are called this
What is a nonbonding pair?
300
a neutral atom that gains electrons
What is a negative ion?
300
when an atom that tends to lose electrons comes in contact with an atom that tends to gain them, this occurs
What is an electron transfer?
300
this occurs when atoms bond to each other in 4 different directions
What is covalent crystal?
300
when the electronegativity of the atoms differs, a dipole may form and the bond is classified as this

400
how strongly an atom is able to tug on bonding electrons has been measured experimentally and quantified as the atom's ______________.
What is electronegativity?
500
atoms tend to lose or gain electrons so that they end up with an outermost occupied shell that is filled to capacity
What is shell model?
500
chemists use this to the right of an atomic symbol to show magnitude and sign or an ion's charge

a group 2 element and a group 16 element combine to form MgO which is more commonly known as this
What is magnesium oxide?
500
another name for a double covalent bond
What is a double bond?
500
the greater the difference in their electronegativities, the farther apart two atoms are in the _________________.
