Valency of the last 5 transitional metals |
+3, +3, +2, +1, +2 |
|
|
Iron has a valency of 2, and reacts with oxygen, what is its compoud. |
FeO2 |
|
|
ACID + BASE = |
SALT + WATER |
|
|
ACID + METAL = |
SALT + HYDROGEN GAS |
|
|
ACID + CARBONATE = |
WATER + SALT + CARBON DIOXIDE |
|
|
Alkali Metal properties and why? |
Very reactive, soft metals Very reactive because only need to gain one electron to react. |
|
|
alkaline earth metal properties |
Reactive metals common in rocks |
|
|
Noble gas properties and why |
stable, very un-reactive don't react because they already have a perfect electron configuration |
|
|
Halogen properties and why |
Very reactive and dangerous non-metals very reactive because they only need to loose one electron to react |
|
|
Neutron Properties |
Neutral charge, mass of 1 |
|
|
Electron properties |
Negative charge, very small mass |
|
|
Proton properties |
Positive charge, mass of 1 |
|
|
Atomic number = |
# of protons/ # of electrons |
|
|
Mass number = |
# of protons + # of neutrons |
|
Protons = neutrons = electrons= |
Protons = 2 neutrons = 4 electrons = 2 |
|
Protons =
neutrons = electrons= |
Protons = 11
neutrons = 12 electrons= 10 plus one electron makes it positive |
|
Protons =
neutrons = electrons= |
Protons = 17
neutrons = 20 electrons= 81 minus one electron makes it negative |
