where are the neutrons and the protons located? |
in the nucleus |
|
|
where are the electrons located? |
outside the nucleus orbiting |
|
|
what is the difference between cloud and orbit view? |
the cloud view is more 3d and more realistic while the orbit view helps show different distances away from the nucleus |
|
|
what is an ion? |
atoms with unequal number of protons and electrons giving a post or neg charge |
|
|
how do electrons effect the mass number? |
they don't they are 2000 x's smaller |
|
|
what makes an atom unstable? |
when protons and neutrons are not balanced |
|
|
is it possible to make 2 different atoms of the same element if so how? |
yes, by changing the number of neutrons |
|
|
how do protons and neutrons effect the mass number? |
each have a mass of 1 AMU ; raise or lower mass by 1 |
|
|
what changes an atom from one element to another |
# of protons |
|
|
if you put all the electrons in the model are they the same distance away from the nucleus? |
no up to 2 electrons can be in first orbit and then 8 |
|
|
if you want an atom to be neutral? |
equal # of electrons/neutrons |
