Q

in the nuclide notation, A,Z, and X stands for

A

A- mass number
Z- atomic number
X- element

17
Q

basic formulas for the calculation of #protons, # neutrons, #electrons

18
Q

these are the atoms of same element but differ in number of neutrons

19
Q

are atoms that have the same atomic number but different mass number

20
Q

atoms that have the same mass number but different atomic number

21
Q

atoms that have the same number of neutrons

22
Q

atoms that have the same number of electrons

A

Isoelectronic

23
Q

it is the number of protons in the nucleus of an atom

A

Atomic number

24
Q

is the total number of protons and neutrons in the nucleus of an atom

A

Mass number

25
is the weighted average of the atomic masses of the isotopes based on their percentage abundance
Average atomic mass
26
make a table with regard to the types of radioactive decay
pic
27
what are the magic numbers used for the prediction of the type of decay
2,8,20,28,50,82
28
these are considered the stable isotopes
magic numbers
29
in the prediction of type of decay, the bigger atoms means it is
electron capture
30
in the prediction of type of decay, the smaller atoms means it is
positron emission
31
what are the steps (you made this yourself) when predicting the type of decay?
1. if Z>83 2. get #p and #n 3. n/p 4. beta or positron/electron capture? 5. is it big or small?
32
these radioactive decays are first order
Kinetics of Decay
33
this is the time wherein the original amount is reduced to half
