Atomic Structure Flashcards
True or false:
Different atoms contain different atoms
True
What are the three particles in an atom
Protons, electrons and neutrons
What is the mass of an electron
0 a.m.u
What is the charge of an electron
Negative
What is the mass of a proton
1 a.m.u.
What is the charge of a proton
Positive
What is the mass of a neutron
1 a.m.u.
What is the charge of a neutron
Neutral
What location are the electrons in the atom
The shells around the atom
What is the location of the protons in the atom
The nucleus
What part of the atom are the neutrons located
The nucleus
Why is the atom neutral
Because the number of protons = number of electrons
What is the charge of the nucleus
Positive because there are only protons and neutrons in the nucleus and the protons are positive and the neutrons are neutral
How do you figure out the number of protons
Atomic number = number of protons
How do you figure out the number of electrons
Number of protons = number of electrons
How do you figure out the mass number
Number of protons + number of neutrons
How do you figure out the number of neutrons
Mass number - atomic number
In nuclide notation What does the top number mean
Mass number
In nuclide notation what does the bottom number mean
Atomic number
RAM=
RAM= (%abundance of isotope 1 x mass) + (%abundance of isotope 2 x mass)
