Ions
Describe an Ion!
A charged atom or group of atoms formed by the addition or removal of one or more electrons
To have a full octet means to..
Have a full shell of valence electrons, which is 8 (except Hydrogen and Helium)
What is the mass of Na?
2NaN3 ----> 2Na + 3N2
(500g) (?) (323g)
177 grams!
These elements are metals or non metals?
Rn, Xe, Br, I, At, & H
Non Metals!
In a gas how do the particles move?
In a rapid motion, colliding with the walls of the container/space
An atom gives away an electron to another atom during the bonding process, would it be positive or negative?
Positive!
The bond that SHARES electrons
Covalent Bond
Is this balanced?
H2O + CO2 ---> H2CO2
YES!
An example of a common compound that is made...?
H2O WATER!
CO2 Carbon Dioxide!
NaCl Table Salt!
C6H12O6 Glucose!
CO2 does not go through the typical states of matter from a solid, to a liquid, to a gas, what do we call it when an object goes from a solid straight to a gas?
Vaporization!
This type of ion typically takes electrons from other atoms and has a negative charge, what am I?
An Anion!
A chemical bond that involves the complete transfer of electrons between atoms is...
Ionic Bond
A chemical equation is balanced by changing....
The coefficients
These elements are metals or nonmetals?
Nb, Rb, Pt, Sr, & Li
Metals!
Changing states from a liquid to a solid, those atoms begin to...
(Move together, Move Apart, or Vibrate against each other)
AND
(have more kinetic energy or less kinetic energy)
Mover together and less kinetic energy!
This type of ion loses electrons and has a positive charge what am I?
A cation!
This bond GIVES or TAKES electrons
Ionic Bond
C2H + O2 ---> CO2 + H2O
Balance it!
2C2H + 7O2 ---> 4CO2 + 6H2O
NaCl is common for which compound?
Table Salt!
Which state of matter do the molecules vibrate tightly against each other?
A solid!
At atom takes away an electron from another atom during the bonding process, is it positive or negative?
Negative!
Bond between a nonmetal and a nonmetal
Covalent Bond
The Law of Conservation of Mass States....
That mass/matter cannot be created nor destroyed
This group of elements are VERY stable, have a FULL outer shell, and have been referred to as "the snobs" of the periodic table...
Group 18 (Noble Gases)
When ice melts, water molecules begin to...
(Move freely, break apart, or release heat)
Move Freely!
