Atomic number = number of protons

mass number = number of protons + number of neutrons

using atomic number we can identify the element from periodic table

part 1

number of protons = 12

number of neutrons=13

atomic number = 12

mass number = 12+13 =25

element with atomic number 12 = Magnesium

Magnesium- 12

$_{12}^{25}\\textrm{Mg}$

********************************************

number of protons = 7

number of neutrons= 7

atomic number = 7

element with atomic number 7= Nitrogen

Nitrogen -7

mass number = 14

$_{7}^{14}\\textrm{N}$

*******************************************

number of protons = 17

number of neutrons= 20

atomic number = 17

mass number = 37

element with atomic number 17 = Chlorine

$_{17}^{37}\\textrm{Cl}$

*************************************

number of protons = 19

number of neutrons= 20

atomic number = 19

element with atomic number 19 = K

mass number Z= 39

$^{_{19}^{39}\\textrm{K}}$

Thank you
