Misc.

100

This is the force of attraction that holds two atoms together as a result of the rearrangement of electrons. 

Chemical bond

200

All compounds are made up of two or more of these 

elements 

300

On the periodic table, elements within the same _____ have the same number of VE

Group 

400

This is the number that represents the ratio of atoms in a compound

subscript 

500

In order to determine the number of valence electrons an atom contains, you must look at this number on the periodic table 

group number

Atomic Structure and Models

100

The nucleus of an atom has a positive charge because the nucleus contains these subatomic particles 

protons and neutrons

200

This English scientist proposed the first atomic model is 1803

John Dalton 

300

This subatomic particle exists in a cloud like region surrounding the nucleus as proposed by the modern atomic model. 

Electrons 

400

These are the outermost electrons of an atom which participate in bonding

Valence electrons 

500

Earnest Rutherford discovered this atomic structure following his gold foil experiment.  

The nucleus 

Ionic Bonds

100

An atom who gains or loses an electron become this 

an ion 

200

in order for an atom such as calcium to become a Ca²⁺ ion, it must do this with it's VE

Lose 

300

This is an ion which contains more than 1 element

polyatomic ion 

400

This is the name of the following compounds

Al₂O₃

Aluminum Oxide

500

This property of ionic compounds explains why salt water can carry electricity 

what is conductivity 

Covalent Bonds

100

This is the bond which contains 1 pair of shared electrons 

single bond

200

Carbon dioxide is a compound which contains 2 of these bond types 

double bond

300

Oxygen is an electronegative element, meaning it typically forms this type of covalent bond as seen in water. 

polar 

400

If two atoms are sharing electrons equally, the bond is said to be this

nonpolar

500

The number of these determines the number of bonds two elements can form 

valence electrons

Metallic Bonding

100

The ability to be hammered into thin sheets is this property 

malleability 

200

This property of metals refers to the ability to absorb and reflect light 

luster

300

This property of metals allows them to work as conductors in light bulbs

conductivity

400

Flowing electrons in a metallic bond allows for the transfer of this as seem in cooking pans

heat

500

this property allows metals to be used as wires in electronics

ductility
