What is a Proton?
Nucleus (+)- positive
Nucleus (=) - neutral
Electron (-) - negtive
None of the above
What dose the atomic # tell us about an element?
The # of protons found found in the nucleus it can also tell us identity of the element. If can also tell us the # of electrons.
There the are the same # of protons and electrons in the element . protons have a (+) charge and electrons havea (-) charge.Their charge.Their charges cancel each other out so they up with a neutral charge.
both
How can an element have a neutral charge?
There the are the same # of protons and electrons in the element . protons have a (+) charge and electrons havea (-) charge.Their charge.Their charges cancel each other out so they up with a neutral charge.
The # of protons found found in the nucleus it can also tell us identity of the element. If can also tell us the # of electrons.
both
If the # of electrons is = to the # of protons the charge will be?
= or neutral
(- )or negtive
+ postive
0%
What if the # of electrons is greater than the # of protons then the charge will be?
+ postive
(- )or negtive
= or neutral
all the above 100%
ifnthe number of electrons is less rhan the # of protons then the charge will be?
+ postive
= or neutral
(- )or negtive
n/a
The periodic tab;e is arranged by perods and groups among other things...what difference between a period and a group ?Where are they found in the periodic tabe?
Group's are arranged in columns and have similar properties
Periods are arranged in rows and have the same# of electrons in their outermost ring
+
=
-
All atoms of the same element have the same?
Atomic #
protons
If you know the # of protons then you can tell what an element is?
protons
Atomic #
What do the acronyms A.P.E. and M.A.N. stand for how their helpful?
click pass #2 is telling you
A=Atomic # =
P= Protons
E= Electrons
M= Mass # - A= Atomic # = neutrons
