Nucleus
Where are neutrons found in an atom?
Nucleus
Where are electrons found in an atom?
Outside the nucleus
Do protons change the element?
Yes
Do neutrons change the element?
No
Do electrons change the element?
No
Do protons change the charge, and in what way?
Yes, positively
Do neutrons change the charge, and in what way?
No
Do electrons change the charge, and in what way?
Yes, negatively
Do protons change the mass of an atom?
yes
Do neutrons change the mass of an atom?
yes
Do electrons change the mass of an atom?
no
What is a isotope?
Same number of protons, different mass number, and different number of neutrons
Definition of isotope
Different atoms of the same element with varying mass numbers and number of neutrons
What are less common isotopes used as?
Tracers
Why are rarer isotopes used as tracers?
They react the smae because they have the sname number of valence electrons.
They can be detected from the most common isotope.
How do you differentiate between a rare isotop and a common isotope?
Through their mass and how radio active they are.
What is the job of protons in an atom?
Tells you the identity.
What is the job of a neutron in an atom?
To hold the nucleus together.
What is the job of an electron in an atom?
Responsible for reactivity; bonding.
