|
If the density of Phosphorus is 1.82 g/mL, and you have 150 mL, what is the mass?
|
d= m/v
1.82=m/150 1.82*150=m m= 273g |
|
What causes an anion to form and what is the charge? Are they larger or smaller than the original element?
|
Anions are negative, and are formed when an electron is gained. That makes them larger than the original element.
|
|
What causes a cation to form and what is the charge? Are they larger or smaller than the original element?
|
cations are positive, and are formed when an element loses electrons. That makes them smaller than the original element. |
|
