How do you identify a During the break, I read the
packet that explains how to
solve chemistry reactions (I
take AP Chem).
I memorized most of the
special exceptions and other
stuff, but I don't get which
are spectator ions.
I thought they are ions that
are soluble, but I see some
soluble ions represented in
the equations.
Only information about
spectator ions I see in this
packet is 'Don't omit any ions
unless you're absolutely sure
that they'll be spectator
ions.'
So How do you identify a
spectator ion in chemistry
reactions?

The spectator is the one that is watching. |

When a positively charged ion For example:
A Sodium ion is positively
charged.
A Chlorine ion is negatively
charged.
When they for the ionic bond
Sodium Chloride, what is the
electrical charge?

neutral |

What is a polyatomic positive I am planning on taking AP
Chem next year and have
regretfully skipped Chem I.
Thus I am stuck teaching
myself everything in Chem I
over the summer. I encountered
these terms in my textbook and
they sound SO FAMILIAR but for
some reason I just can't find
any material to help me.
How do I tell if an ion is
positive or negative?
And what is a polyatomic
positive ion?
Thank you so much in advance;
I'm sure I'll have many more
questions!

Go get yourself Chemistry for Dummies go to websites that focus on reading the periodic table With the periodic table label the first column 1+ the second 2+ the third colume 3+ the next to last column 1- the column to the left of that 2- and one more to the left again 3- whatever column an element is in look at the sign i just stated above to determine if positive or negative ions created and with what charge - example potassium (K) is a positive ion with a 1+ charge. An ion is an element that has either lost or gained electron(s). A potassium ion lost an electron therefore; the ion now has more protons than electrons. Since protons are postive the ion has a positive charge. Look at Al (aluminum) It has a 3+ charge because the element lost 3 electrons turning it into a postive ion. , On the flip side, the flurine (F) likes to gain one electron so now has more electrons than protons. Since electrons are negative and has more of them it becomes a negative ion with a 1- charge. This is only one small part of chemistry and is hard to teach yourself (this was one small part of one chapter) find a tutor somewhere! Your smart to get a jump on it now! |
