Perodic Table Flashcards
What’s the definition of an Isotope
Atoms with the same atomic number but a different mass number
Atomic number equals what
The number of protons
Are proton positively charged True OR False
True
Are neutrons negatively charged particles true or false
False
What charge he does electrons have
Negatively charged
What dose the mass number = to
Number of protons + neutrons
Number of neutrons = ?
Mass number - atomic number
What dose a and b represents
A
_X
B
A is Mass number
B is atomic number
Answer the question you’ll need a calculator
Find the RAM if
abundance of 35^Cl atoms, 75% compared to 25% other 37^Cl
RAM =(75x35)+(25x37)

=35.5 a.m.u
How do you fine the relative atomic mass
RAM=
(% abundance of isotope 1 x mass)+(% abundance of isotope 2 x mass)
